What is possibly happening is that when it boots off a USB drive is it is reassigining controller IDs. A typical boot.ini may look something like this: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003 for Small Business Server" /noexecute=optout /fastdetect C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons The bit we're interested in is: multi(0)disk(0)rdisk(0)partition(1)\WINDOWS If the (presumably SATA? that you normally boot off) controller is no longer treated as controller 0 by the BIOS, then that's why this issue is occurring. I suspect this is the case but I'm yet to get anyone at HP who seems to have a clue about the problem. Anyway, if so you may need to alter this line to be, say, multi(1)disk(0)rdisk(0)partition(1)\WINDOWS Thanks for that! It is working now :thumbs: I had to make the partition active on each of the USB drives as you said in Disk Management then I copied over boot.ini and ntldr. I then had to make the boot.ini like this: multi(0)disk(0)rdisk(1)partition(1)\WINDOWS The 1 was a 0 originally.	CYaBro (73)
