NTDetect Failed after I boogered the registry
Posted on 2009-02-23
I had persistent problems with a BSOD and used WinDbg. The problems, for the most part, appeared to be related to Symantec's Corporate AntiVirus program. I deleted the program - that didn't help - so then I deleted a bunch of the entries in my registry that were apparently (I thought) related to the program and I'm guessing I went a little to far and deleted a necessary file. In trying to boot the computer, I get a "NTDetect Failed" error flashing briefly after the BIOS screen and then it cycles back to the beginning of a reboot - over and over again. I never get to the Windows screen with the blue progress bar.
Last Known Good doesn't work, Safe Boot doesn't work, ran chkdsk /r from Recovery Console - it found and corrected one error, but didn't fix the problem. I ran a Repair from the Windows Install disk - that didn't work either. I used Dell's Diagnostics and everything passed the Express Test. I'm trying to repair the problem without installing a fresh copy of WinXP, and am running out of ideas. Is there anything that I can do short of installing a parallel install of WinXP (C:\WINDOWS2)? If I do that parallel install, will it work and will I be able to run my installed applications on the first WinXP installation? Will I be able to repair the first installation of WinXP and then delete the parallel installation? Thank you
