A simplistic way to look at it is that the stuff on the DVD image is in the wrong place when it is put on a USB or hard drive. So your BIOS does not see it as a bootable device. Now, if you could fool the BIOS into thinking it was a USB DVD drive instead of a USB storage device, it might work. The DVD image does not start out with a valid boot loader signature when treated as a floppy or hard drive. For an optical drive, the boot signature is not in the same place. (This is only part of the problem, but it is the first problem encountered.) Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
