My XP Pro system refused to start after I shut it down in the middle of what I thought was a failed attempt to run dskchk(black screen, no hard drive activity). It would not start up under any circumstances, including last known configuration and safe mode. I was able to get everything working and run dskchk from the recovery console. Everything is working fine except for two things. 1) Unable to enter safe mode, it either freezes or simply skips over the process and starts Windows normally. 2) Still unable to run dskchk. It attempts to run at every start up, but the "cannot open volume for direct access" error message comes up. There is no anti-viral or anti-malware running at start-up, which can apparently cause problem #2. Everything is working perfectly, but obviously these two issue indicate that all is not right. Is there any way to save this install(which is only 4 months old)? Thanks.
