Can Get To Normal DOS To Try And Recover Files

Hadn't been on the computer for a couple of days, when I did I saw that Norton had found 2 high risk viruses (I don't recall what they were). I selected to fix both of them and it seemed to work. I also noticed that I had about 10 My Computer folders open. It then told me to reboot the computer, which I did. When the computer restarted, it seemed to power up OK, it then said starting Windows, and it went to the log-in screen. (I have two log-ins, one for me and one for my wife). When I click on either one of the two log-ins, it automatically says saving settings and logging off, and then it goes right back to the two log-in selections. I have tried to log-in in Safe Mode, and every other option available to me, and I get the same outcome. I tried the Recovery Disk that came with the computer, and it would not boot from the CD drive, even when I changed the settings to boot from the CD Drive. It tried to star once and I hit R for a Standard Recovery and it seemed to start, then I got a BOOT: Memory overflow error��..Please insert another disk and it just locked up. I rebooted and I could not get back to the recovery menu. It just sits there with a black screen with a blinking cursor and then I get the following error. �Disk Boot Failure, insert system disk and press enter�. And it does the same thing now every time I try it. Is there a way I can just get to normal DOS to try and recover my files?
