I want to make my 8 gb flash drive into a bootable flash drive to boot off of to install xp vista and 7... i have an xp home and pro i have a vista any time upgrade disk and i found a all in 1 windows 7 install.... Ive looked around and tried several of the ways ive seen online and every one of them seems to fail... multibootiso gives me an error saying the drive wont be mountable.. ive used magic iso and used the multi boot image creator option but then that doesnt seem to work with the things ive seen.... any suggestions?
