How to make your USB drive Write-protected under Windows

Many of you may be aware that recent versions of Diskpart (after WinXP) have the ability to set 'Read-Only' attributes on a disk or volume. I decided to investigate this feature a bit more thoroughly and this is what I have found. If you already know about this feature then don't stop reading, what I discovered may surprise you!

First, we have to distinguish between the two types that Windows separates 'disks' into - namely 'Removable' and 'Fixed'.

Now in the case of USB Flash Drives (UFDs), most of these are classed as 'Removable'. In the case of USB Hard Disks (UHDs) these are all (??) classed as 'Fixed' (or 'Local' in Explorer). RMPrepUSB will indicate which type of disk it is when you select it. Diskpart will list the types if you use the 'LIST VOLUME' command - you will see either 'Removable' or 'Partition'...

DISKPART> list volume

  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     E                       DVD-ROM         0 B  No Media
  Volume 1     I                       DVD-ROM         0 B  No Media
  Volume 2     G                       DVD-ROM         0 B  No Media
  Volume 3     D   HDD DRIVE_D  NTFS   Partition     10 GB  Healthy
  Volume 4     C   HDD DRIVE_C  NTFS   Partition    222 GB  Healthy    System
  Volume 5     Z   HDD1_500GB   NTFS   Partition    465 GB  Healthy    Pagefile
  Volume 6     F   SSD HARD DI  NTFS   Partition    111 GB  Healthy    Pagefile
  Volume 7     H   LEXAR JD     FAT    Partition     15 MB  Healthy
  Volume 8     J   USBPEN       FAT32  Removable   1992 MB  Healthy


We can list disks in Diskpart using;
LIST DISK
We can list volumes in Diskpart using:
LIST VOL
We can select a disk or volume using:
SEL VOL 8   or    SEL VOL J   or
SEL DISK 3
We can see what the RO status is using
DETAIL DISK or DETAIL VOL

Current Read-only State : Yes
Read-only  : Yes

Note that the Current Read-only State signifies the current state in Windows and not the state of the disk - for instance, if there is a physical write-protect switch on the USB drive which is set to 'Lock', then the Current Read-only State may be Yes, even if the actual disk state is write-enabled (Read-only : No).

Once we have selected a disk or volume, we can set or clear the Readonly attribute.

Attribute disk set readonly
Attribute disk clear readonly
Attribute vol set readonly
Attribute vol clear readonly

So under Diskpart we have two options when setting 'ReadOnly' status and we have two types of 'disk'.

Here is what happens in each of these 4 cases:

1. Type=Removable, Set Disk=RO
Diskpart makes a change to the Windows Registry - no change is made to any sectors on the disk.

2. Type=Removable, Set Volume=RO
N/A - Diskpart will refuse to run as the disk is removable.

3. Type=Fixed, Set Disk=RO
Diskpart makes a change to the Windows Registry - no change is made to any sectors on the disk.

4. Type=Fixed, Set Volume=RO
Diskpart makes a change to the Windows Registry AND changes the disk contents.
If the drive is an MBR type (not GPT) then all volumes are marked as write-protected.
The MBR and all sectors up to the Partition Boot Record are not protected by Windows however.
If you connect the USB drive to a different Windows system (even a WinXP system), you will not be able to copy files to any volume on the drive. This also applies to UFDs that appear as 'Fixed' disks to Windows.

Now you may be already aware of this behaviour. However, I decided to investigate what disk contents were changed in Scenario 4 above. This was quite easy using RMPrepUSB. I simply made a single 20MB FAT16 partition on a Lexar Jumpdrive UFD that had it's Removable Media bit flipped using the Lexar BooIt.exe utility so that appeared as a Fixed Disk, and then used the RMPrepUSB - Drive->File button to save an image of all sectors up to the end of the partition. I then used Diskpart to set the Volume to Read-only and saved another image and then compared the two images.

The results were rather surprising. Diskpart had completely overwritten the contents of LBA2 (the 3rd sector) of the UFD! It had written 24 bytes of data followed by 488 bytes of 0's to fill the sector. Even if you have boot manager code in this sector, it is overwritten by Diskpart! Luckily this does not seem to stop grub4dos from booting if it was already installed to the MBR and pre-PBR disk sectors.

The bytes that were written were: 
0000 A2 A0 D0 EB E5 B9 33 44 - 87 C0 68 B6 B7 26 99 C7  ¢ Ðëå¹3D ‡Àh¶·&™Ç
0010 00 00 00 00 00 00 00 10 - 00 00 00 00 00 00 00 00  ....... ........
0's etc. etc.

These bytes don't seem to vary, even when Diskpart sets Volume RO status on a 2TB NTFS multi-partition UHD.

However, I found that if you write-protected a 'Fixed' disk Lexar UFD in this way and then 'flipped' the Removable Media Bit to make it a 'Removable' drive again, Windows XP-Win8 no longer treats the volume as write-protected. So this special read-only marker sector only works on 'Fixed' disks and not on 'Removable' disks. :-(

So what if we format a 'Fixed Disk' UFD with RMPrepUSB, install grub4dos to the MBR, and then 'blat' LBA2 with the 'write-protect' sector data... Yep - works fine! The volume is write protected and we cannot copy files to it. If you try to format it in Windows then it won't format it:



However, as the MBR and early sectors are not protected by Windows, we get a strange result if you try to re-partition it using RMPrepUSB. RMPrepUSB erases the early sectors, but then Windows prevents it from erasing the Partition Boot Record and RMPrepUSB returns an error. The volume, PBR and all files are still present. However, if you unplug the USB drive and re-connect it, because LBA2 is now wiped by RMPrepUSB, the USB drive is no longer 'Read-only' and so we can partition and format it using any utility.
You get similar strange results in Disk Manager, which can seem to unformat the partition and return it to 'RAW' status, but not re-format it until the Read-only status has been removed using Diskpart!

So it seems we cannot use this Diskpart Attribute feature to write-protect Removable UFDs... what a pity! If however, you have a UFD that is of the 'Fixed' disk type or you 'flip-the-RMB-bit' using a utility like BootIt (which only works on some Lexar and Netac UFDs and a few other types), then you can have a protected volume using this feature.

P.S. If you have a 'Removable' USB drive, you can hide a partition containing your files by making a drive with two Primary partitions using Easeus Partition Master and then use the RMPrepUSB - Ctrl-O feature to swap Windows access between the two partitions. This does not stop someone from re-partitioning it however and modern Win10 systems can now access all partitions on a Removable drive anyway.

You can write-protect some SD cards and Flash drives if you use the correct special factory utility to reprogram it. This process is not without risk however, and you could end up 'bricking' your flash drive or SD card. You must always use the correct tool. See here.

File Permissions (NTFS)

To protect all files from alteration under Windows, you can change the Windows file permissions on all files on a USB drive.

First select the USB drive in Windows Explorer - right-click and select Properties and then the Security tab. Now click the Edit button and untick the Full Control, Modify and Write boxes - then click on OK. All files on the drive will have their permissions changed. Windows can still add new files but cannot modify or delete any of the existing files. Unfortunately, these permissions are ignored by (most?) linux distros and grub4dos.



Note: If you have a USB HDD with multiple partitions, you can hide any of them from Windows (not linux) by using BootIce - Manage Part - select partition - Hide. When you next connect the USB drive the partition will be hidden. if you unhide it with BootIce, it will immediately be unhidden.

Write-Protect NTFS drives

NTFS Drive Protection is  small Windows executable that can change the NTFS permissions on an NTFS volume. You can use this to write-protect a USB drive, but it also allows for some folders on the drive to be read/write whilst all others are read-only.



Keep this on yout USB drive and run it just before you connect the USB drive to an infected system.



E2B v1.15d

In v1.15c, if you reloaded the main menu, then the hotkey codes like ^Ctrl+B etc were displayed in the Menus and hotkeys didn't work. This is now fixed in v1.1d.
Also I found FASTLOAD was not working. This also now fixed in v1.1d

Thanks to Krishna for reporting the bug.

v1.15e will also beep when the FASTLOAD Main menu loads if beep is set.

Easy2Boot v1.15c

v1.15c includes a few tweaks for people who don't like the grub4dos messages during E2B boot-up.

patchme has been revised so that you can now optionally disable the grub4dos version header at the top of the screen which briefly appears whenever grub4dos loads a new menu file - previously, for a brief few milliseconds, you may have noticed this text at the top of the screen (or part of it).

GRUB4DOS 0.4.5c 2013-10-17, Mem: 636K/1022M/0M, End: 34C2AB

The new version of patchme will remove (optionally) this message and all of the other grub4dos startup messages. This means that a system can boot to E2B with no text messages at all once you have patched it with patchme.

The other changes are to do with startup messages too. Using settings in your MyE2B.cfg file, you can enable the background image to be displayed as soon as it is loaded - any progress messages will be displayed over the top of the background (the only drawback is that the screen won't scroll properly if the cursor gets to the bottom of the screen - so if you have lots of files, set redir=> nul to prevent them all from being listed). An example is shown below (the console text has been set to white in the MyE2B.cfg file in this case):


Alternatively, you can just have a pure blank screen (of whatever colour you have set the standard console background colour too, default=black) right up until the Main menu is displayed. Except for the first few milliseconds, no cursor is displayed either.

As usual the Sample_MyE2B.cfg file contains all the settings details. Here are a few of the relevant lines from it:

#Examples
### Use this line for a blank screen startup with no progress messages
### Tip: use patchme to prevent grub4dos messages (see \_ISO\docs\PatchMe_readMe.txt)
#call Fn.70 0 ;; clear ;; call Fn.5 0 128 ;; set redirp=> nul ;; set redir=> nul
#
### Use this line to display the background image as early as possible with a few progress messages
#call Fn.70 3 ;; set redir=> nul 
#
### Use this line to display the background image as early as possible with no startup messages except an initial quick 'Please wait...' message
#call Fn.70 3 ;; set redir=> nul ;; set redirp=> nul ;; debug -1 ;; pause --wait=1 Please wait... ;; debug 0

Experiment with any one of these three options to see which one you like the best for your E2B project.

Note that you need v1.15c for these to work properly - it can be found at the bottom of Tutorial 72a as usual.

bump - please update to E2B v1.15b

Just in case you subscribe to this blog, E2B v1.15 has been updated a few times since yesterday and is now at 1.15b. It includes a bugfix for FASTLOAD which was broken in v1.15.

Tuesday 22 October 2013

Easy2Boot v1.15b available (bugfixes)


  • bugfix - Krishna reported that it no longer works if you have 2 partitions and swap them over. Now fixed.
  • bugfix - payload files in the \_ISO\AUTO folder were not enumerated below the first folder level. Now fixed.
  • feature - Menus should now not show the menu item number at the top right of each menu when using the cursor keys.
  • bugfix - PTN2_Menu.mnu in \_ISO\docs\Sample Menu files now checks for the non-E2B partition even if you have swapped partitions over using E2B_PTN_SWAP.mnu to change over the two partitions.
Please update to the new version. Sorry for the bugs!

Few more bugs found - 1.15b is now the latest!

Monday 21 October 2013

Easy2Boot v1.14 available


  • Just some extra variable tweaks added for those of you that really want to play around with the menu structure!
  • Also added a 'beep' feature - when the Main menu loads, you can make it beep 1 to 3 times by setting the beep variable in your MyE2B.cfg file.
  • If only one XP ISO, or only one Vista/7/SVR2K8 xml file is found, then it will now be automatically selected for you so you are not presented with a choice of 1 thing!
  • Menu numbering can be turned off (AUTONUM=0)
  • more global hotkey examples added to Sample_MyE2B.cfg
  • New WinInstMain theme template example added to docs folder
As always, look in the Sample_MyE2B.cfg file for all the new tweaks and settings.
The web page for E2B (72a) has been updated to match v 1.14 features.

Let me know if you find any bugs!

P.S. Some bugs were found. Now v1.15 is available!

cheers

beep! beep! (in grub4dos)

I had a request today from a blind person who wanted the grub4dos menu to beep when it loaded so that he would know when the countdown timer had begun. He was following my 'Tutorial 89 - Automated Windows partition backup\restore boot menu using CloneZilla' and wanted to be able to hit F4 and automatically restore his system.

Unfortunately not all hardware is fitted with a small internal speaker or internal 'beeper'. Most PCs are however - this is the thing that you may hear beep when you switch on your PC or it may beep several times if you have dislodged the DIMM memory cards!

Assuming that your PC does have an internal beeper, we can make it beep by sending a Ctrl-G character to the 'console'.

In grub4dos, we can use the internal function Fn.2 to send Ctrl-G to the 'display' as follows:

call Fn.2 7

This will work if you place it at the top of your menu before any graphicsmode or splashimage calls are made, because the display must be in low-res text mode (CGA) for this to work. So if you want to try this make sure you type graphicsmode 3 first if you are already in hi-res mode after loading a hi-res background bitmap! Of course, as this is a hardware 'beep', it won't work in an emulator or VM either.

We can flash the screen white and beep 3 times using the code below, as long as it is at the start of our menu.lst file (all one line).

color standard 0xF1 && clear && call Fn.2 7 && call Fn.2 7 && call Fn.2 7 && pause --wait=3 > nul && color standard 0xf && clear

If you don't want to see a flashing cursor use:
call Fn.5 0 128 
after the first 'clear' command, this sends the cursor off the screen to row 128! It will also mean that if the calls to Fn.2 produces any odd characters, they won't be seen.

However, once we have switched to a hi-res graphics mode, this trick of sending Ctrl-G to the 'display' will no longer work. Instead we will have to call the BIOS directly to output Ctrl-G to the console.

We can do this using the nice little grub4dos executable 'bios' from Chenall (download the bios.zip from here).

To make 3 beeps, each one second apart in any resolution screen mode, we can use this (assuming the bios executable is in the root of the drive):

/bios int=0x10 eax=0xe07 ebx=0x0 > nul
pause --wait=1 > nul
/bios int=0x10 eax=0xe07 ebx=0x0 > nul
pause --wait=1 > nul
/bios int=0x10 eax=0xe07 ebx=0x0 > nul

Most notebooks and many 'All-in-One' PCs are not fitted with an internal speaker though, so we can't make an annoying noise on every system that we boot from...

Easy2Boot - How to add specific Win7/8 Install ISO entries to the E2B Main Menu

Recently, I was asked if E2B could just jump straight to the Windows menu as he just wanted to use an E2B USB Flash drive for Windows installs. He also wanted to have the different individual ISOs listed in the Main menu.

The best way to just show a 'Windows Install' menu is to de-populate the Main menu by removing all the \_ISO\MAINMENU\*.mnu files that you don't want to be listed in the Main menu, and then add one or more .mnu files for your specific Vista/7/8 Windows Install ISO files using the type of menu entry described in my E2B Tutorial page here (or see below for an example). You can also add the Win XP options too.

You can also specify an XML file using a .mnu file.

In this way we avoid the Windows sub-menus and just use the Main menu. The \_ISO\MAINMENU\ZZWindowsInstall.mnu file is the one responsible for the Windows sub-menu entry in the Main menu, so this can be removed if you don't want it in the Main menu.

If you remove the files and folders in the other \_ISO\xxxx folders, then the DOS, BACKUP and UTILITIES, etc. menus won't be listed in the Main menu as only populated folders are listed. Other entries in the Main menu (set default, F8-10) can be disabled by using a MyE2B.cfg file (see the Sample_MyE2B.cfg file for the available options - use v1.13 or later!).

An example of a .mnu file is shown below:

# Use this for Vista/SVR2K8R2/Win7 ISOs
iftitle [if exist /_ISO/WINDOWS/Win7/Win7_32_SP1.iso] Install Win7 SP1 32-bit \n Install from the ISO
set MFOLDER=/_ISO/WINDOWS/Win7
set ISO=Win7_32_SP1.iso
/%grub%/RunVista.g4b  Win7
boot

# use this for Win8/8.1/SVR2012 ISOs
iftitle [if exist /_ISO/WINDOWS/Win8/Win8.1_32.iso] Install Win8.1 32-bit \n Install from the ISO
set MFOLDER=/_ISO/WINDOWS/Win8
set ISO=Win8.1_32.iso
/%grub%/RunWin8.g4b  Win8
boot

iftitle [if exist /_ISO/WINDOWS/Win8/Windows_8.1_EN-US_x86.ISO] Install Win8.1 32-bit \n Install from the ISO
set MFOLDER=/_ISO/WINDOWS/WIN8
set ISO=Windows_8.1_EN-US_x86.ISO
set XML=
# Specify XML file in MFOLDER folder (e.g. Win8\ has\ spaces\ in\ name.xml)
# OR to choose XML or Product Key, comment out next line
set XML=Sample.xml
set NOWMENU=1
/%grub%/RunWin8.g4b  %MFOLDER% %XML%
boot

Have you tried WinMerge?

WinMerge is great for comparing source code and other text-based files (like E2B files!). It is similar to WinDiff but better, IMHO!

If you have two different versions of a bunch of files and folders, WinMerge will list all the different files for you. Then double-click on the file and it will display the two versions of the file in two side-by-side Windows and highlight the differences. You can copy individual lines from one file to the other or just copy the whole file to the other folder. It works on all files and so will show non-identical binary files too.

It is great for comparing two versions of E2B (or any text-based files).
If you download the latest version of E2B to a folder and then compare that folder with your E2B USB drive, it will highlight the changes and you can decide what to update and what to leave alone (or just copy over a few lines inside a file).

A must-have for anyone who works with code source files or wants to compare two different versions of a bunch of files!

Easy2Boot v1.13

There were some small issues with v1.12 like pausing if a gfxmenu was loaded, global hotkeys not being active on all menus and the NoF8B variable not suppressing the F8 entry in Vista/7/8 menus. The new sample theme TextMinimal has also been changed.
Please update to v1.13!
See here for the latest version.

Thursday 17 October 2013

Easy2Boot v1.12 available

Changes are:
1. If E2B boots as a floppy disk, grub4dos 4.6.a is then loaded which has USB drivers and may treat the USB as hd0 and so work as the great BIOS god in the sky intended!
2. 100K spaces.txt file now removed as no longer required.
3. Global hotkey function added using chenall's great new hotkey version - you can define hotkeys without needing to have a  menu entry for it. See \_ISO\Sample_MyE2B.cfg for details.
4.  Warning message shown if an .iso file is not contiguous.
5. Fix for .iso files hanging - in previous version some HP systems hang when booting an .iso file - this was due to the loading of a firadisk floppy disk image in the E2B QRun.g4b code which seemed to cause the problem, so that line has now been removed (thanks to Colin for reporting and debugging with me to find this issue)
6. Startup message suppression using redir and redirp improved - can now have silent startup.
7. NOF7HD variable will suppress Boot from hd0 menu entries.
8. NOF8B variable will suppress the 'Return to Main Menu [F8]' menu entry in the Windows menu (delete MAINMENU\ZZZF8ReloadMenu.mnu if not wanted in Main menu).

See here for this version.

If you update your version to v1.12, you can delete the \_ISO\e2b\grub\spaces.txt file as it is no longer required.

Tip: If your system has slow USB boot speeds, try using the latest version of grldr (get file from \_ISO\e2b\grub\grldr_46a and copy to root of E2B drive and rename to grldr).

If you try this new v1.12 version of E2B please let me know if it works for you (better or worse) or if it has a problem. It should look the same as the previous version but work on more systems and report any errors better. I will leave v1.11 on the site so you can go back to it if there is a problem.

If you want to replace \grldr with the 0.4.6 version, please give it a try. As it is new, I have not fully tested it...

Tutorial 72a Easy2Boot v1 web page has been updated to add v1.12 features. For example, I show how to just skip the Main menu and show the Windows Install menu on startup.

cheers
Steve

P.S. There were a few small issues with 1.12 so please upgrade to 1.13!

Swap partitions in Easy2Boot

In my previous blog entry I described how you could create a USB Flash drive with two partitions. The E2B menu will work when it is on the 2nd partition and run linux ISOs, etc. but the E2B partition will be ignored by Windows and thus not visible to the user.

However, this also means that Windows based Operating Systems, once they have booted from the USB drive, will not be able to see any files on the 2nd (E2B) partition. This means that Windows Vista/7/8 Install ISOs will not work because they won't see the AutoUnattend.xml file on the 2nd (E2B) partition.
Also, several versions of Windows PE, once they have booted, will try to access files and folders on the boot drive. A typical example of this is MiniXP on the Hirens Boot CD and spin-offs such as DLC.

Apart from copying these files (AutoUnattend.xml and \HBCD folder, etc.) to the 'user' visible partition, the other alternative is to swap partition 1 with partition 2 before we run Hirens or the Windows Install ISOs.

This can be done by adding a .mnu file to E2B.

I have added E2B_PTN_SWAP.mnu to the \_ISO\docs\Sample mnu Files folder in the E2B download files. Just add this .mnu file to your \_ISO\MAINMENU folder.

You should now see a new menu entry in your menu. If Easy2Boot is detected on the first partition then the menu entry will be
  • Hide E2B Partition 
If Easy2Boot is detected on the 2nd partition, then the menu entry will be:
  • Unhide E2B Partition
When you run the menu entry, it will swap over ptn1 and ptn2 and then reload the main menu.

So before running a Windows Install you can Unhide the E2B partition and then Hide it again afterwards. The same applies when you want to run Hirens MiniXP or MiniWin7.

Make a 'secret' Easy2Boot USB Flash drive

Krishna wanted a USB Flash drive with Easy2Boot on it, but he wanted it to appear as a normal flash drive if anyone looked at it in Windows. This was mainly to prevent others from seeing and changing the E2B files and 'breaking' it.

The way this can be done is quite simple actually, and I have added a section to the E2B Tutorial here to explain how to do it. Basically you just make an E2B USB Flash drive in the normal way but create a smaller partition to leave room for a 2nd partition. Then, when E2B is all working correctly, add the second Primary partition using the spare space on the drive and then use RMPrepUSB to swap over the two partitions (using Ctrl+O). Now Windows will only see the second partition and you cannot access the E2B volume.

[Edit]Note: This only works on pre-1607 Win 10 (Creator) versions. Later versions of Win10 can access all primary partitions on a Removable USB drive now!

The USB Flash drive will still boot to E2B just fine though!

To gain access the the E2B partition, just run RMPrepUSB to swap the partition order back again.

E2B also allows you to add a master password to prevent it from being run by just anyone and you can also 'encrypt' many of the files in E2B by compressing them so that they are not easily read by curious users using Notepad. You can also change the file attributes of all E2B files to Hidden+System to further obscure them if you wish!

P.S. Note that if you are booting E2B to Vista/7/8 or WinPE, then those OS's will also not be able to access the USB E2B partition. This means that Vista/7/8 Installs from ISO will not work. Also any PE 2/3/4 (e.g. Hirens Mini Win7) will not be able to see any files on the E2B 2nd partition, so you will need to place those files and folders (e.g. \DLCD) on the non-E2B visible partition.

Note: Add a menu entry to E2B which will swap over the 2 partitions so that Win Installs and Hirens, etc. will work and you won't need an extra USB Flash drive, see here for details.

Later versions of E2B can 'super-hide' the E2B partition by making it unaccessible to Windows.

Run OpenELEC LIVE from your Easy2Boot USB drive

You can also run OpenElec Live (i.e. run XBox Media Centre - XBMC, and play video, music and internet TV, etc.) directly from your Easy2Boot USB drive.

See below for 2014 version - the next instructions are for the 2013 version.

----- 2013 version -----


If you have a FAT32 E2B USB drive, then download the appropriate version (I used Generic i386 Version 3.2.2) and extract the KERNEL and SYSTEM files from the target folder and place them in the root of your E2B drive (actually you could move the KERNEL file if you changed the path in the .mnu file).

Then make a .mnu file for E2B as follows:

title OpenELEC
uuid () > nul
set UUID=%?%
kernel /KERNEL boot=UUID=%UUID% disk=FILE=STORAGE,512

This will cause OpenELEC to make a 512MB ext4 file called STORAGE on the root of the E2B USB drive when it first boots. This is used to hold all the OpenELEC downloaded files, changes, etc.

Adding OpenELEC to an NTFS E2B Drive

If your Easy2Boot USB drive is formatted as NTFS however, you need to follow these steps:

1. After downloading the OpenELEC .tar file, unpack it to a folder on your Windows hard disk.

2. Copy the KERNEL and SYSTEM files to a spare, freshly formatted FAT32 USB Flash drive - this should be formatted as the size of the two files + 512MB + 10MB. Don't make it any bigger as this will make the final image file bigger and waste space.

3. Add the following menu.lst file

uuid () > nul
set UUID=%?%
kernel /KERNEL boot=UUID=%UUID% disk=FILE=STORAGE,512
# if it exists, change the type 0C 4th ptn entry to 0
cat --locate=\x0c --number=1 --length=1 --skip=0x1f2 --replace=\x00 (hd0)+1


4. Install grub4dos (use RMPrepUSB - Install grub4dos - Yes=MBR).

5. Boot the spare USB flash drive on a real system - it should create a 512MB STORAGE file (or less than 512MB if there is not enough room on the USB drive) and then run XBMC. Test it out and check add-ins are working and remembered when you reboot.

6.  Make an image of the partition on the USB drive using RMPrepUSB - Disk->File - choose P1 for Start, P1 for End and 0 for the File Start position.
I will assume the file created is called Open_Elec_LIVE.img

7. Now copy the Open_Elec_Live.img file to your E2B NTFS USB drive's \_ISO\MAINMENU\Linux folder. Then create an Open_Elec_Live.mnu file in the same folder as below:

title OpenElec LIVE \n This runs OpenElec from an image file
# Write a permanent new entry into the E2B partition table pointing to the OpenElec partition
partnew (hd0,3) 0x0 %MFOLDER%/Linux/OpenElec_LIVE.img
root (hd0,3)
chainloader (hd0,3)/grldr

8. Run WinContig (RMPRepUSB - Ctrl+F2).

You should now be able to boot and run Open_ELEC XBMC from the image file.

This worked a treat on my Asus EeePC 904H when booting from my E2B NTFS USB hard disk!

P.S. Rather than run grub4dos twice, you could combine the two menus into just one menu for the .mnu file:

title OpenElec LIVE \n This runs OpenElec from an image file
# Write a permanent new entry into the E2B partition table pointing to the OpenElec partition
partnew (hd0,3) 0x0 %MFOLDER%/Linux/OpenElec_LIVE.img
root (hd0,3)
uuid () > nul
set UUID=%?%
kernel /KERNEL boot=UUID=%UUID% disk=FILE=STORAGE,512
# if it exists, change the type 0C 4th ptn entry to 0
cat --locate=\x0c --number=1 --length=1 --skip=0x1f2 --replace=\x00 (hd0)+1


or load the 2nd menu directly, by using this .mnu code:
title OpenElec LIVE \n This runs OpenElec from an image file
# Write a permanent new entry into the E2B partition table pointing to the OpenElec partition
partnew (hd0,3) 0x0 %MFOLDER%/Linux/OpenElec_LIVE.img
root (hd0,3)
configfile /menu.lst



----- 2014/2015/2016 versions -----

Tested on:

  • OpenELEC-Generic.x86_64-6.0.3.tar
  • v 5.0.6
  • OpenELEC-Generic.x86_64-4.0.2
This assumes you have the MakePartImage Tool Kit folder present on your system and you have installed ImDisk and made the Desktop Shortcuts (as in the ReadMe file).

Instructions:

1. Download the OpenElec .tar file

2. Extract the Target folder containing the kernel and system files to a folder on your system hard disk - e.g. C:\temp\target

3. Drag-and-Drop the C:\temp\target folder to the MPI FAT32 Desktop shortcut - when prompted, specify the target as C:\temp\OpenElec.img

4. Run RMPrepUSB with the E2B USB drive connected and selected.

    Make a \OpenElec-rw Ext3 Filesystem file with a Volume Label of DATA. The size is up to you!

5. Copy the OpenElec.img file to the \_ISO\MAINMENU\MNU folder of your E2B drive.

6. Create a .mnu file in the same folder with the following contents (this file can also be found in \_ISO\docs\Sample mnu files\OpenElec\OpenElec_LIVE_2014_NTFS.mnu on your E2B drive):

# For NTFS E2B USB drive (or FAT32)
# Create a FAT32 partition image file from a folder containing the kernel and system files from OpenElec using MPI Tool -> OpenElec.img
# Make ext2 FS file in root of E2B drive - FileName=OpenElec-rw  VolumeName=DATA
# Copy this .mnu file and OpenElecUSB.img to \_ISO\MAINMENU\MNU folder

iftitle [if exist not /system if not exist /kernel] OpenElec Live\n Boot OpenElec with persistence

cat --locate=\x0c --number=1 --length=1 --skip=0x1f2 --replace=\x00 (hd0)+1

7. Run WinContig on the E2B drive (RMPrepUSB Ctrl+F2)

Notes:
  • When booting from VBox, OpenElec fails to start Xorg and said 'Is your GPU supported'. Use a Nightly-build that will work on Virtual Box - the stable versions don't run on VBox.
  • Error in check_disks: could not repair filesystem - If OpenElec started to boot OK but then failed, and now does not start at all and gives this error message immediately - re-make the OpenElec-rw file - it may have been corrupted due to an untidy shutdown/reset.
  • When booted from my Z87 mainboard using a slow USB HDD drive, it failed to find the system file and did not mount the USB HDD drive. However, a USB Flash drive in the Z87 USB 3.0 port did work. I booted it on my Asus Aspire 7741G notebook from the same USB HDD, and it did work.
If your E2B drive is a FAT32 volume, then you don't need to make a .img file, you can just copy the system and kernel files to the root of the E2B USB drive and modify the menu as follows:

# --- FAT32 E2B USB DRIVES ONLY ---
# Just copy \system and \kernel files to root of E2B USB drive
# Make ext2 FS file in root of E2B drive - FileName=OpenElec-rw  VolumeName=DATA
# Copy this .mnu file to \_ISO\MAINMENU\MNU folder

title OpenElec Live\n Boot OpenElec with persistence
set PER=/OpenElec-rw

if "%E2BDEV%"=="" set E2BDEV=hd0 && pause E2BDEV forced to hd0!
if exist CD echo WARNING: Cannot use partnew command! && pause && configfile (bd)/menu.lst
debug 1
parttype (%E2BDEV%,2) | set check=

set check=%check:~-5,4%
# make empty table entry in 3rd position in ptn table
if "%check%"=="0x00" partnew (%E2BDEV%,2) 0 0 0
if not "%check%"=="0x00" echo WARNING: PTN TABLE 3 IS ALREADY IN USE! && pause
debug 1
if not exist %PER% echo WARNING: %PER% persistence file not found! && pause
errorcheck off
if "%check%"=="0x00" partnew (%E2BDEV%,2) 0x0 %PER%
errorcheck on

uuid () > nul
set UUID=%?%
echo %UUID%
kernel /kernel boot=UUID=%UUID% disk=LABEL=DATA quiet


P.S. The latest build from here worked under VBox when booting from my Easy2Boot USB drive. I actually downloaded OpenELEC-Virtual.i386-devel-20140317134709-r17946-gb27c946.tar.

How to add OpenELEC XBMC Installer to Easy2Boot

The OpenElec x86_64 installer is based just on two files from the \target folder, KERNEL and SYSTEM. The KERNEL can be loaded by grub4dos but then it will look for the SYSTEM file on the boot volume. This works fine if we just copy these two files from the OpenElec x86_64 download to the root of our FAT32 Easy2Boot drive and then use a simple .mnu file:

title OpenElec Flat-File boot from FAT32
uuid () > nul
set UUID=%?%
echo UUID=%UUID%
kernel /KERNEL boot=UUID=%UUID% installer



However, there is a problem if we have an NTFS Easy2Boot USB drive because the KERNEL does not appear to be able to access the NTFS filesystem to find the SYSTEM file.

See here for OpenELEC Live.

Method 1 - use MakePartImage


1. Use RMPrepUSB - File->Drive and write the  OpenElec.img file to a spare USB Flash drive (this will destroy all contents on the USB drive).

2. Drag-and-drop the USB drive Explorer icon (e.g. J:) onto the MPI_FAT32 desktop shortcut (after installing the MPI Tool Kit).

3. Copy the resulting OpenElec.imgPTN file to your E2B USB flash drive

You can now MBR boot or UEFI boot.

Method 2 - the harder way!


After some trial and error, here is the way I found around this.

1. On a spare USB Flash drive, format it with RMPrepUSB as FAT32 and make the partition size just large enough for the two files + about 10MB. e.g. if the files add up to 92MB make a 110MB FAT32 partition. We need to keep this as small as possible as we are going to create an image from it.

2. Install grub4dos to the MBR

3. Add the two OpenElec boot files, SYSTEM and KERNEL.

4. In RMPrepUSB, press F4 to create a menu.lst file and add these 5 lines

uuid () > nul
set UUID=%?%
kernel /KERNEL boot=UUID=%UUID% installer
# if it exists, set the type 0C 4th ptn entry to 0
cat --locate=\x0c --number=1 --length=1 --skip=0x1f2 --replace=\x00 (hd0)+1

We should have these files on the FAT32 grub4dos Flash drive:
\grldr
\SYSTEM
\KERNEL
\menu.lst

5. Test that it boots to the OpenElec installer by pressing F11 in RMPrepUSB

6. In RMPrepUSB, click on the Drive->File button, choose a destination to save the file (OpenElec.img) and enter P1 for the Start Position on the drive, then P1 for the End Position and then 0 for the File Start position. This will create an image of the entire partition.

7. Copy the OpenElec.img file to \_ISO\MAINMENU\Linux folder of your E2B drive (or any \_ISO\xxx\Linux folder if you want it in a different menu).

8. Create in the same folder  an OpenElec.mnu file containing these contents (cut and paste the 5 lines):

title OpenElec Installer \n This installs OpenElec to a drive
# Write a new entry into the E2B partition table pointing to the OpenElec partition
partnew (hd0,3) 0x0 %MFOLDER%/Linux/OpenElec.img
root (hd0,3)
chainloader (hd0,3)/grldr

Now Run WinContig (RMPrepUSB - Ctrl+F2) and we should now be good to go!

We should now have present on the E2B drive:
\_ISO\MAINMENU\Linux\OpenElec.img
\_ISO\MAINMENU\Linux\OpenElec.mnu

Select the OpenElec Installer entry in the Easy2Boot Main Menu and it should boot.

The trick here is that partnew is used to create a type 0C partition entry in the E2B USB drive partition table so that we do have a real partition on our E2B drive when OpenElec boots, however once it boots to the image and we have loaded the kernel in grub4dos, we can set the partition type to 0 because linux does not look at the partition type number. This means that when E2B reboots, it will not complain about the partition table Entry #4 being in use and refuse to load the main menu. If E2B sees a Type 0 in ptn #4 it will clear the entries for us.

Neat eh!

The installer seems to install OK on a VM hard disk, but the VM seems to fail to fully boot to OpenElec (probably wrong hardware?) and I haven't tried it on a real system as it will trash the system's hard disk.



Raspberry Pi netbook for £100(ish) !

I have had my Raspberry Pi for a while now and after getting XBMC running on it, I have not really used it for much. I recently saw on YouTube that people have been connecting the Pi to the Motorola lapdock accessory for the Motorola Atrix 4G smartphone (really smart, RRP was over £300 but now reduced to £70 on eBay due to the phone being discontinued by Motorola!).

If instead of the Atrix 4G (which is no longer made), you plug in your Raspberry Pi and you now have a Raspberry Pi netbook with an 11.5" screen, internal battery, speakers, touchpad, keyboard and 3 spare USB ports all for about £100! Add a wifi dongle and you have a wireless Pi.

I have written a few notes on this here. There seem to be many YouTube videos describing how to split and solder special cables for the Pi<->lapdock connections, but this is not necessary. You can power the Pi straight from the USB cable if you have a later revision of the Pi. If you have an earlier Pi, simply solder two wires across the two 500mA fuses F1 and F2 (these are not fitted on later versions anyway, so you are actually upgrading your Pi!):
Pi mod. - Click to enlarge.

This bypasses the 700mA fuse in the mini-usb power in connector on the Pi, but the lapdock has it's own protection built into the USB ports.

BTW - Fuses should be used safety reasons and not for limiting the current; why the Pi has a 700mA fuse in the supply power input to supply power to the Pi circuitry + two 500mA USB ports baffles me - the main fuse in the Pi should be 1.5A at least! There also should be larger reservoir capacitors to allow hot-plug of USB devices!

After doing this mod to F1 and F2, I had a nice working Pi netbook. Unfortunately, I discovered that the brand new lapdock I got from Mobilepartz on eBay had a faulty trackpad button and so I have had to return the lapdock for a replacement, which they kindly agreed to, without any fuss or problem.

When I get the new one back, I will add some pictures of my setup and probably a few more notes/tutorials on the Pi.

Update: Steve of Mobilepartz sent me a replacement on the same day that he received it and rang me to confirm. The new one works perfectly and is now running raspbmc and playing live TV nicely - it seems I was just unlucky with the first one (both were brand new). Great service Steve, thanks!

My WiFi-enabled PiDock!

RMPrepUSB and FastFlashTest versions updated

Just a quick note to say that RMPrepUSB has been updated to v2.1.714 and FFT to v1.0.8.

RMPrepUSB 2.1.714 now uses 7zG, the windows GUI version to extract files after the drive has been formatted instead of the console version 7z.exe. Also the 'Make ISO from grub4dos USB drive - Ctrl+M' function has been improved so that the ISO made from a WinPE USB drive will now boot correctly if your USB drive contains \boot\BCD or a boot.wim file (auto detected). You can also add the oscdimg.exe file to the RMPrepUSB\QEMU folder and the Ctrl+M function will automatically use oscdimg to make the ISO file instead of using mkisofs. For instance, if you have a bootable WinPE (Win7/8) USB drive that uses the grub4dos bootmanager to load it, the Ctrl-M function will now make a bootable ISO from it.
