• Menu hotkeys changed in all STRINGS.txt files
• AUTOMENU feature added - can now press first letter of a menu entry to select it, 
• Current language displayed in footer HELPTEXT (can be changed in MyE2B.cfg).

• Small speed improvement in counting Windows ISOs. 
• New version of hotkey utility (thanks chenall!). 
• New version of grub4dos 0.4.6a.

See previous blog posts for details.

The new MPI Tool Kit now centres the heading and payload description in the CSM menu and the \menu.lst is re-organised to help you make modifications more easily. It also now has hotkeys for F7/F9/F10 and first-letter menu hotkeys too. New grub4dos 0.4.6a is used too.

If you want your own background and menu for the CSM menu, just use the CUSTOM folder in the download to add any new or replacement files.

E2B website now in Klingon

I had an email from a very cross guy called Khan today, asking me to provide instructions on how to make an Easy2Boot USB drive that are written in Klingon, as his Earth-English is not very good.

So Khan, please click HERE.

 (OK, not really)... ;-)

E2B 1.65d Beta available

1. Chenall has fixed a few bugs in new grub4dos and the new hotkey utility.
2. The Menu hotkeys have changed (they all use Ctrl key now).
   The Windows Install Menu is now Ctrl+I not W plus some others have changed!
3. New wallpaper to signify change of hotkeys
4. Grub4dos password entry now needs SHIFT key before pressing p. Same for c, b and e.
5. Changed the way I detect Admin rights in Make_E2B_USB_Drive.cmd and QEMU_MENU_TEST.cmd.
6. Grub4dos 0.4.5c/0.4.6a menu and USB driver menu moved from Main menu to Utilities menu.

As soon as chenall fixes and releases new grub4dos 0.4.6a I will release this new version.

Spot the changed hotkey assignments and new wallpaper!

E2B v1.65b with auto-hotkey feature

This new Beta has the updated grub4dos hotkey utility which chenall has kindly enhanced for us!

I have also improved the speed of the code that counts Windows ISOs.

Menu on my E2B drive used for testing, etc.

The new AUTOMENU hotkey jump feature is now enabled by default. e.g. press the f key and the Fedora menu #18 will be selected (but not run). Press the f key again and Fedora menu #19 will be selected.

Which is the best Portable app. Launcher for your USB drive?

It is often useful to have portable apps on your USB drive, so that you do not have to install any applications or drivers on the system that you are trying to use or fix.

Portable apps launchers are great, but most often you will need to run a launcher from a WinPE environment rather than a full Windows OS with .Net and WoW64 (the Windows-on-Windows 'thunking' which allows Windows to run a 32-bit application in a 64-bit OS).

Many of the portable apps themselves are 32-bit only apps (and thus require a full 64-bit OS or WoW add-ins), but what about the Launcher apps? If these require a full blown OS to run in with .Net, etc. then we cannot even run the Launcher app to choose a portable app!

Note: Check out PEStartup for a 32-bit and 64-bit alternative for WinPE OS's here.

pendriveapps.com - A 'library' of all free portable apps with links. Useful for finding and adding portable apps to your launcher!

E2B v1.65a (Beta) supports centered headings

After making the YouTube video about configuring the menu and centering menu headings, I thought that maybe I should support automatically centered menu headings. This would save having to manually modify all the STRINGS.txt files just to have centred menu headings.

So E2B v1.65a will now centre Menu headings if you add

set CENTREHD=1

to the \_ISO\MyE2B.cfg configuration file.

If the value is 1, then E2B will use the menuw  (menu width) setting to calculate where the centre point of the menu is. This would be the normal use for it. So if menuw is 65 then E2B will use 65 as the menu width for centering the headings.

However, you can specify your own value for CENTREHD. For instance if your menu width is 65 characters, but you want your menus to appear a little bit to the left of centre, use a CENTREHD value of say, 60 instead of 1.

The Beta is available in the Alternate Download areas. Let me know if you find a problem!

Tidbit: Freda, a female acquaintance of mine, named her red setter puppy Heathcliff because she is a big fan of Emily Bronte. However, it turned out not to be such a good idea, She takes it for walks on the Chiltern hills, and if it gets lost, she goes wandering all over the hills shouting 'Heathcliff, Heathcliff'! The other dog walkers look at her like she has just escaped from the local asylum!

New E2B YouTube video - how to change the menu position, colours and headings

I have had a few requests by people to make a MyE2B.cfg for them and also a request on more info on how to change and/or center headings.
So here is a new (quite long!) video.
Hope you don't fall asleep watching it!

E2B 1.64 released

Just fixes two issues in 1.63

1. Long-standing issue - If you run XP Setup, when it gets to the first 'Welcome to Setup' blue screen, it will change the Disk Signature of the internal hard disk that you are about to install XP to. If you then abandon the install by rebooting, the OS that you had on the internal hard disk may no longer boot (BSOD - 0xc000000e  inaccessible boot device).  This has now been fixed.
   Tip: It could be repaired by using 'bcdboot D:\Windows /s C:' after booting to a Windows Install ISO console window.
2. The new version of  \_ISO\docs\E2B Utilities\E2B TXT Maker.cmd caused a problem if you try to make a .txt file for a Windows Vista/7/8/10 ISO file. The 'if exist' conditional code has now been removed because it is not needed in .txt files, because the .txt file is only used if the ISO already exists.

Files are available from here as usual.

To update your E2B USB drive, download and extract the smaller non-DPMS version to a new, empty folder and then run the UPDATE_E2B_DRIVE.CMD script.

Add HitManPro to your Easy2Boot USB drive

A previous blog post here described how you can add and run HitManPro from an E2B USB Removable Flash drive (NTFS or FAT32). The E2B USB drive must be of the 'Removable' type - it won't work if your E2B  flash drive is of the Fixed-disk type (a USB HDD will not work either - Hitman will not auto-run when you boot to Windows).

HitmanPro needs to see a Removable USB drive which has some special code in the sectors at the very end of the USB drive (currently they use the very last 55 sectors).

I have written a grub4dos batch file HitManXfer.g4b (included in Easy2boot) which will transfer these sectors from a valid HitManPro USB Flash drive to the end of your E2B USB flash drive.
