7b = INACESSIBLE_BOOT_DEVICE. It's usually caused by a bad path in BOOT.INI, a missing storage driver (like installing Windows on a SATA drive without hitting F6 during setup to specify a SATA driver), or other miscellaneous controller issues. Is this a SATA drive? If so, did you use a driver during setup? If not, you may need to make a floppy disk with the SATA driver on it. You can usually find a disk maker on the motherboard CD (OK choice), and at the motherboard manufacturer's website (better choice).
