I have an 8gb Disk Go drive. So i unplug all the HDD and boot with an XP disk, but only have the flash drive in? This will make the flash drive bootable? I am not trying to install XP on the flash drive. I want to be able to plug in a flash drive and load the OS onto the computer through USB. I have been told it is possible and is a lot quicker then doing it through the CD-Rom. In my line of work I am constantly loading computers, we have just moved to Vista and it has become a pain.
