Hello all,

I need to have the possibility to install Windows7 or Windows8 with same USB.

Any ideas?

I can install only once, windows7 or windows8 but i don't have any idea how to make it possible to select witch one I want to install.

I already tried to use YUMI to boot the .iso files, but that didn't work :(

Any ideas?

I imagine you'd need some sort of custom loader... It's been done in the past with software like the "6 in 1 windows XP super CD"... I have no idea hot it's done, but it can be done if you find someone who knows how to program.

Yeah a custom loader is the smoothest way of doing it, the only other thing i could think is to partition the USB and have the 7 installer on 1 partition and 8 on the other...then at boot the "2" USB drives would show as boot options and you choose the one you want...
The only immediate problem would be know which is which...but the 1st partition should be 1st in the list.

I can YUMI to make the bootloader.
The problem is:
- I can use YUMI to boot the .iso of windows7 and windows8. YUMI will creat the proper menu to select the ISO, but there are some issues while installing windows from ISO file.

- I can, also with YUMI, to extract the files from windows7 OR windows8 to root and install correctly. But in this case I can only have w7 or w8..

I've always wondered if somebody got this to work. It would be pretty awesome to have a 32GB flash drive with every version of Windows on it to select from.

+10 internets to the first person to get it working. :D

Looks like people do not have a good experience from trying this, but a few options to try here

Another possible method

still didn't find a function way to make it. None of the available options seams work.

I think its a nice tool to be able to select witch one OS we want to install...

Already wrote a guide about it. Should work on USB sticks too.
