Grub2 Menu system Beta 6 available for E2B

The new Beta 6 version of the grub2 menu system is available in the Alternate Downloads Area.

By default, it now does not use a grub2 theme because on some systems, it seems to cause a very slow menu response in MBR-boot mode.

You can now change the menu text colours in the \ISO\MAINMENU\grub2\defaults.txt file.
You can also specify a wallpaper .jpg or .png file to use as a background in the defaults.txt file too.

E2B v1.90 now released

The changes from v1.89 are mainly for WinBuilder ISOs and tidying up files in the root folder of the USB drive:

v1.90 2017-02-18 (v1.91 Beta has a small bugfix to stop the 'WinBuilder ISOs must end in .ISO' message.)

1. Support for WinBuilder_ISO.mnu sample menu file (see here)
2. Remove 20 character filename limit for WinBuilder ISOs (.isoWB files)
3. Add three common WinPE .ini files to root of drive
4. QRUN.g4b will auto-detect WinBuilder .ISO files and automatically update the .ini files to correctly boot and load the ISO as Y: drive
5. Moved sample Windows XML files to SAMPLE XML FILES folders (user must copy them up one level if needed)
6. \_ISO\CONTIG.ISO is now not updated/copied by the update script
7. Make_E2B.exe updated to latest version (QEMU button inactive if no E2B drive selected)
8. If user sets hidden file attribute on USB:\menu.lst file, then Update script will hide most files in root each time
9. The three .cmd scripts can be moved by user to \_ISO folder to keep the root tidy

If you are updating your E2B drive with v1.90, you may want to:

1. Set the hidden attribute on \menu.lst first, and then run the Update script. This will cause most of the files in the root of the E2B drive to be hidden.
2. Move the three v1.90 .cmd files in the root of the E2B drive to \_ISO folder to keep the root folder looking tidy.
3. Delete any unwanted XML files in your \_ISO\WINDOWS\xxxx folders to reduce the number of XML files listed by E2B. They will not be replaced when you update in future.
4. If you have any WinBuilder-based ISOs (e.g. Gandalf, ChrisR WinPESE's, WinPE-Yol, Dium, MediCat, etc.), you might like to try just leaving them with a .ISO file extension (and ensure no spaces in the filename) and see if they 'just work' without needing any other .WB file, etc. See this page if you want to remove the QRUN auto-suggest messages each time it runs.
5. You can just rename the download to .zip and extract it as usual if you wish.
6. Delete the 500MB \_ISO\CONTIG.ISO file to save space - any future update will not replace it.

Configure Windows Install ISOs with WinReducer

A recent PC Welt article described WinReducer which may be of interest to you.

This is a utility that allows you create bespoke Windows Setup files (.ISO or a USB drive). It also creates an AutoUnattend.xml file for you.

It is not too obvious how to get started and the Tutorials link did not seem to be working on the site, but you can watch a Video here.

It does nag you to Activate (purchase a licence) a lot too!

I still haven't worked out what the difference is between ES and EX versions!

Quickly make a USB drive to directly UEFI-boot from Ubuntu ISOs

If you follow Tutorial #136, you should be able to UEFI-boot directly from most Ubuntu-based ISO files.

Just copy the ISO file to the \efi\boot folder on the USB drive and rename it as boot.iso.

This is a way to quickly prepare a UEFI-bootable USB drive.

It relies on the ISO containing a \boot\grub\loopback.cfg file.

At a minimum, only two files are needed on the USB drive, the ISO and a .efi boot file.

Make a generic grub2 boot menu (using loopback.cfg)

If you have ever tried to boot directly to a linux ISO file, then you will know that it is necessary to tell the linux boot kernel/scripts where to find the ISO file so that it can load it as a 'cdrom' (loop) device and access the files inside the ISO. If this is not done, you will typically see a 'squashfs file not found' error message!

Typically we can fix this by specifying a kernel parameter or 'cheat code'.

A typical grub2 command line which loads the Ubuntu boot kernel and specifies the location of the ISO file would be:

linux (loop)/casper/vmlinuz.efi boot=casper iso-scan/filename=/_ISO/ubuntu64.iso quiet splash

This allows us to boot from a grub2 USB drive (say), mount the ISO as a loop device and load the kernel and initial ramdrive files from inside the ISO file and then pass on the location of the ISO file so that when the linux kernel boots, it can re-load the ISO file as a loop device again (because the first loop device is lost when the linux kernel loads).

So to boot to linux in this way, we need to know what all these parameters need to be.

The problem is that they vary from version to version and distro to distro and we always have to do some 'research' and experimentation to try to find out what parameters we need. There also may be several menu entries (for live cd, install, safe mode, memtest, etc.) and we would need to make grub2 menus for each of them.

Enter the loopback.cfg file!

However, some distros, such as Ubuntu, contain a useful loopback.cfg file (located at \boot\grub\loopback.cfg).

Here is a typical Ubuntu loopback.cfg file which is inside the ISO file:

Make fancy E2B wallpapers, collages, web graphics, etc. with a web-based photo editor

I got some junk email this morning asking me to visit the www.fotojet.com and review it.

Normally, I immediately delete such emails, but today I thought I would take a look...

Installing linux using E2B

If you use an E2B USB drive to boot from a linux ISO or .imgPTN file, you will often run into a problem if you are trying to install linux onto a system.

Many linux OS installation scripts or GUI's will look for the source linux files on a 'CD-ROM' drive, because they 'think' that we have booted from a CD or DVD.

I have added a new page to the E2B site here, which details how to specify the location of the linux source files.

Easy2Boot v1.90c BETA

Version 1.90c Beta has the following changes from v1.89:

• Automatic support for WinBuilder-based ISOs (e.g. Gandalf, Dium, Yol, ChrisR PEs)
• The three most common INI files used by WinBuilder ISOs now added to root of the E2B drive
• QRUN.g4b improved to automatically detect WinBuilder ISOs
• WinBuilder ISOs are checked to ensure no spaces in filename and end with .ISO extension
• UPDATE_E2B_DRIVE.CMD will automatically 'tidy' files if \menu.lst is hidden by user
• Windows 7/8/10 XML files now in SAMPLE XML FILES subfolders. To use them, copy them to the appropriate folder, e.g. from \_ISO\WINDOWS\WIN10\SAMPLE XML FILES to \_ISO\WINDOWS\WIN10

v1.90c is available from the Alternate Downloads Areas as usual.

How to keep things tidy!

Easy2Boot v1.90b BETA now available

E2B v1.90b now has three extra blank files added:

• \Win7PESE.ini
• \Win8PESE.ini
• \Win10PESE.ini

These are the most common .ini files used by WinBuilder ISOs.

I have also modified QRUN.g4b so that if you try to run an .ISO file that contains WinBuilder files inside the ISO, QRUN will update the three .ini files with the name of the ISO. The WinBuilder PE OS should then automatically load the ISO as a virtual Y: CD drive when it reaches the Desktop.

This seems to work for most normal WinBuilder ISOs (e.g. made using ChrisR's project or TheOven projects) and also Gandalf, MediCat and WinPEYol ISOs, etc.

With most WinBuilder ISOs, you need to follow a few rules though or WinBuilder won't load the ISO as drive Y: correctly:

E2B v1.90a Beta has improved WinBuilder ISO support

As an alternative way to boot WinBuilder ISOs such as Gandalf WinPE WinBuilder ISOs, starting with E2B v1.90, you can also use a simple .mnu file.

The v1.90a Beta includes a sample WinBuilder_ISO.mnu file which you can copy and modify for each of your WinBuilder ISOs.

# WinBuilder sample .mnu file - example for Gandalf x86 64-bit WinPE 2016-11 version (requires E2B v1.90 or later)

# click on the Desktop Yellow Warning Triangle to find .ini file name for each WinBuilder ISO

# ISO filename must not contain spaces or it won't be loaded as Y: virtual CD!!!

# You must create the \WIN10PESE.ini file in root of E2B drive and fill it with 1000 characters of random junk

title Gandalf PE 64-bit WinBuilder ISO\n Boot a WinBuilder ISO

set ISOFN=Gandalfx64WindowsPE.iso

set IniName=WIN10PESE.ini

if not exist $HOME$/%ISOFN% echo ERROR: $HOME$/%ISOFN% NOT FOUND! && pause

if exist     $HOME$/%ISOFN% call /%grub%/QRUN.g4b force.isoWB $HOME$/%ISOFN%

boot

So all you need are three files:

• \WIN10PESE.ini - must be approx 1K (any contents)
• \_ISO\WINPE\MNU\Gandalfx64WindowsPE.iso
• \_ISO\WINPE\MNU\Gandalfx64WindowsPE.mnu - the .mnu file

This saves having to make a WB folder and a xxxxx.WB file although this method is still supported in v1.90.

The improved code in QRUN.g4b also checks that the filename does not contain spaces and removes the 20-character filename limit/bug that was in previous versions of E2B.

E2B v1.90a will be uploaded in a day or so to the Alternate Download Areas!
