I recently got the (d***able) windows XP Security 2012 virus on an older computer of mine (probably 7 or 8 years old) and I tried to remove it as best I could. I deleted the file in safe mode, rebooted the comp. and then reset the system to the last restore date (sometime in December, I think the 17th). After I did the system reset, I tried to boot up the machine. It successfully got to my home screen, but then it cut out and restarted. I tried to restart the computer, but now my freakin BIOS is no longer finding my hard drive. It only gives me the option to boot from a disk or from my nonexistent network. Do you think that my timing was bad and the hard drive was doomed to give out, or would resetting my computer have damaged anything? Do you have any suggestions how to get the computer to read the drive, or is all hope lost? Thanks for any help!

Well,you can remove the hard drive and put it into an enclosure.Plug it into your new PC as a slave.Then you can copy your files off it. Then reinstall Windows.
If the hard drive shows up in ‘my computer’ as a drive letter(like E: drive) but you can’t access it,you can recover your data with data recovery program.Tenorshare data recovery is a professional one that can recover data after deeply scanning your hard drive to look for lost data due to drives crash, system sabotage, virus attack,etc.You can get it here: http://search.yahoo.com/search?p=Tenorsh…
After you recover your data,you can format it to check out whether it can be fixed.
Can get it recognized?
Turn the computer off without the external hard drive being plugged in.
plug the external hard drive in a usb port, power up, the systems post boot up will find the drive and inform windows what hardware is installed.
When windows boots up, it will look at all the hardware and find the external hard drive, when windows finishes booting up you should be able to see the drive.
It could be that your hdd just blew but normally there would be some sort of hindering that it is about to go like grinding sounds, blue screens, and slowness. You can try plugging the hdd into a different SATA port on your motherboard or testing the hdd in another computer but I do not think that restoring your computer would completely break your hdd.
Use your Windows CD to do a repair to the boot sector of the hard drive.
