Run chkdsk and System File Checker (SFC) from the Recovery Console

• Boot your Vista or Windows 7 installation DVD
• When you see "Press any key to boot from CD or DVD", press Enter
• At the "Install Windows" screen, click on Repair your computer at lower left
• At the System Recovery Options screen, make note of the drive letter assigned to your boot drive (normally C and click Next
• At the Chose a Recovery Tool window, click on Command Prompt. You will be sitting at X:\Sources directory
• Run chkdsk or SFC
  • If you did not note the drive letter of your boot disk, you can enter bcdedit and look at the osdevice line to see what it is.
  • For chkdsk, type chkdsk c: /r and press Enter (use the letter from above if not C.
  • For sfc, type sfc /scannow /offbootdir=c:\ /offwindir=c:\windows and press Enter (use the letter from above)

Let either run to completion undisturbed.

Vista or Windows 7: If you don't have a install DVD, you can download a legal copy here:
Windows 7 Direct Download Links
Download Official Windows Vista RTM with SP1 Setup Files (32-bit and 64-bit)

Make sure you get the same version you have installed: 32 or 64 bit; Home Premium, Pro or Ultimate.

In addition everything possible to repair unbootable Win7 is here for Troubleshooting Windows 7 Failure to Start.

I would first boot into BIOS setup to see if the HD is detected, then if so run the diagnostics provided in addition to Disk Check as Rich suggests
