Booting to Windows XP

I'm having a problem booting to Win XP. I get a blue screen telling me there was a problem with a program and something about winsrv. I have been trying to get rid of that pesky spyware Home Search thing and in the process deleted some files from my windows\system32 folder that I shouldn't have. The thing is I have those files in a backup folder in C:\Documents and Settings but I can't access them anyhow to copy them back to where they should be. And no, I didn't write down the list of files or else I could have gotten them from my roommates computer.

I think the question I'm asking is how can I boot my computer up to DOS mode with access to my entire hard drive and copy files from one location to another? Any suggestions?

Thanks in advance.

 

Can you give us the exact error message?

 

Nevermind :> I got a WinXP disc and did a repair instead of a restore and that worked. Now I gotta get rid of that stupid spyware problem....

Thanks for your willingness to help.
