Recently I purchased a hdd caddy to use hdd as primary boot device. It show in bios as fixed drive. Problem asises upon installing Windows 7. After the first restart, windows installation starts from beginning.
Try removing any other drives to give Windows a hint of where to go. It also might help if you slave the drive to another PC and formatting it in NTFS and allocate to the drive letter as C:
