When you installed the HD, and if it's an IDE, did you jumper the HD correctly (jumpers on the HD)?

Primary IDE, first HD (C:), set jumper as Master (do NOT trust Cable Select aka CS)

Primary IDE, second drive (HD or CD-ROM), set jumper as Slave

For Secondary IDE, use same jumper scheme, first device = Master, second device = Slave.

NOTE: With CD-ROMs on IDE, it is best to have the drive on its own cable, set Master. If the CD-ROM is on the same cable as a HD, HD = Master & CD-ROM = Slave. This is due to the data trough-put being set by whatever is Master and CD-ROMs are slower.
