Bootdisk problems

[Nooomz]

before i get into the problem,
1) im running vista,
2) i am using iprep,
3) im doing this throw usb,
4) and i have a ms28

okay so the problem is that when i go to my boot device menu, or just have the usb booted, i get the problem..

Selected boot device not available -
strike F1 to retry boot, F2 for setup utility

any clue of what to do?

oh and note: when i go to my bios to make sure that it boots from USB it doesn't say 'UNAVAILABLE' or not found or anything like that like 2 or 3 of the other devices in the list.

make sure you put "boot from other device " on top and "boot from harddrive on bottom

mine i had to put boot usb zip in 1st boot then cd then hard drive
