Does the drive still work outside of the Windows operating system? You can check this by putting in a bootable cd or dvd, then restart the system. The boot order in the bios must be set so that the computer tries to boot from the optical drive first. Looking at the online manual for your computer, the default setting is to look for the optical drive before the hard drive, but if you need to get into the bios, you hit F10 as you start the computer. (might be F2 or F6 though)
If it is working properly, the optical drive should show up in the bios also.
Examples of bootable disks include a retail version of Windows operating system, a live Linux cd or something like the Ultimate Boot CD. http://www.ultimatebootcd.com/
All you’re trying to do with the bootable disk is a diagnostic test…to see if the drive is still functioning.
