recover files on corupt hard drive

Well I reaklly screwed the pouch this time. I had a Dell Dimention 8400 with windows xp sp3 on it. I was having problems with my virus scanner, and Mcafee ran a chkdsk saw errors and said I needed to clean those up. I used chkdsk /f /r

Nothing seemed to be happenning after 15 min I rebooted. You guessed it I must have corrupted some files I cannot boot to safe mode or reg windows.

1. How can I boot using recova?

2. get old files that are not corrupt??? ---

3. How would I know which files I needed to recova?

I have 2 dvd drives and usb ports on the back, NO FLOPPY.

Your quickest way may be to burn a linux livecd and use that to recover what files you can to a usb drive.

If you are unsure about how to do this here is a very recent quite good and easy to folllow write up on how to do this using Puppy Linux. Suggest you read it all through first.

As Hazelnut insinuated, it is not possible to use Recuva as a pre-boot program.
