creating a 2 OS thumb drive

Despite the Pendrivelinux site name, the program requires windows:

YUMI - Multiboot USB Creator (Windows) | USB Pen Drive Linux

I still use an older version to install XP, Windows 7, and load UBCD and Linux mint Live:

It loads a grub4dos bootloader to boot from the usb, then you can edit the menu.lst to boot into linux, or Windows install iso images:

default 0
timeout 30
color NORMAL HIGHLIGHT HELPTEXT HEADING
splashimage=/splash.xpm.gz
foreground=FFFFFF
background=000000

You can load as many iso entries as your usb drive has space for.

Many thanks for the reply.

You inspired me. I just did it.

1. Copy the contents of the x86 dvd/iso onto a partition. I used partition G. So I had a folder G:\GRM.... ( or a similar long list of letters). Rename the GRM... folder to x86 - that makes it easier. You now have G:\x86 as the folder.

2. Copy ONLY the install.wim from the x64 installation media onto the same partition. You now also have G:\install.wim. Rename that to Win7x64.wim. You now have G:\Win7x64.wim

Like this: Attachment 47641


3. Put a copy of Imagex in Windows\System32 of the o/s ( Vista or 7) you are booted into.

4. Open an elevated command and type the following - press enter after each line and wait for it to complete ( it's quick) : [obviously, replace G: with the letter of the partition you have the files on ]

Imagex /export "G:\Win7x64.wim" 1 "G:\x86\sources\install.wim" "Windows 7 Home Basic (x64)"

Imagex /export "G:\Win7x64.wim" 2 "G:\x86\sources\install.wim" "Windows 7 Home Premium (x64)"

Imagex /export "G:\Win7x64.wim" 3 "G:\x86\sources\install.wim" "Windows 7 Professional (x64)"

Imagex /export "G:\Win7x64.wim" 4 "G:\x86\sources\install.wim" "Windows 7 Ultimate (x64)"

5. Delete the ei.cfg file from the x86\sources folder.

6. You can now use the contents of the x86 folder to create a bootable flash in the usual way . All editions of 32 and 64 bit can installed from it.

Or make a bootable .iso from the x86 folder.

The .iso is only 3.65gb

Have fun.

This works perfectly, Thanks SIW2.

You can reduce the size of install.wim substantially by removing the languages you don't need - all of them , if you just want english.

Can't remember how much it takes off - near 1gb iirc.

You have to do it for each edition - takes a while if you are bothering with more than one edition.

Oddly, vlite does it very well.

Yes, same process - there is no ei.cfg in Vista from memory.

It will be quite big though, Vista editions had different contents - not purely incremental like win7.
