multi boot usb stick

[legopc]

so i just got my 2x 32gb usb sticks in and i was wandering is there a programm that allows me to make this into an install usb stick thingy but then with multiple windows versions (server 2008r2 w7 w8)

YUMI has worked fairly well for me.

Rufus I use

[.:MARK:.]

You could just put grub on a USB, then extract each ISO to a folder and direct grub to the bootable folder of the OS installer...

I guess the program does the same thing.

Well yes, once you reformat the drive it has to wipe everything. There should be an option through the process to select multiple ISOs.

the wiping is no problem it just writes over the files of the win install

If you have the Windows installation as an ISO, Yumi shouldn't edit it at all, just write files to mark it as an installation. You are scrolling down to the bottom of that distro list it gives you and choosing unlisted (Grub) right? Once it finishes, there should be a popup asking if you want to add more ISOs.
