Hai,
Check in the BIOS whether the HDD is listed or not.(Is detected or not).
If yes
Try Pressing F8 repeatedly during boot or Go to BIOS and change default BOOTING DEVICE to HDD.
If error still occurs, Try inserting a windows recovery CD or Installation Disk and then using 'repair' Try 'Automatic Fixing' or 'Command-line ' type "bootrec/fixmbr" and bootrec/fixboot.
Let me know the results.
