Hi, I'm having trouble with a laptop XP SP2 that crashed with a power outage. It hangs on drvmain.sdb. On my laptop, I see that file is in c:\i386. So I know this is a stupid question, but I'd like to be able to get to a command prompt to copy the drvmain.sdb file from the I386 directory into the c:\windows\apppatch directory where its hanging on the file. It hangs there even when I try to boot into safe mode with command prompt. I need to boot from a CD or something to just bring up the system at a command prompt. Would I just put the original XP CD back in and do a restore? Any suggestions?
