I have created an unattended XP install for a project. Problem the total file size is 1.3 Gb so it wont fit on a CD, it may go on two but id prefer to run the setup from a usb pen as this can be edited a lot easier and quicker than writing to CD. I has to be possible to do this as I can run a standard XP install from an external usb CD Drive, so i know its possible to use the USB ports during the install. I also know that the computer I will be installing to has the capability to boot from a usb key/pen, and also a usb HDD. The computer recognises my pen drive as a USB HDD in the BIOS. Can anybody tell me how this can be done. I have tried creating a bootable usb pen but i havent got a boot disk to get the files from and when i create a floppy boot disk I get a different set of files which the HP USB pen formatter doesnt recognise. PLEASE HELP, ive only got a few days to get this done and ive been searching the web all weekend
