I installed ZoneAlarm firewall and during the install it said that one part coudn't be installed completely because I wasn't administrator (however I was) and it continued installing and finished. Later that night I started to get the BSOD. The exact message was: *** STOP: 0x00000024(0x0019025E, 0xEB27EA50, FTFS_FILE_SYSTEM 0XEB27E6A8, 0xBFEA21F8, 0xBFEA21F8) *** BFEA21F8 base at BFE9700, Date stamp 42807cdd, -Ntfs.sys I was able to boot to safe mode, that's what I'm posting this in now. After finding this forum I've booted with my original W2K installl disk and went to "Repair a Windows 2000 installation Using Recovery Console" I've run 'chkdsk /R' on all my partitions, after running chkdsk twice there were no errors found on any of the partions. I then tried booting back into window but still got the BSOD. While in safe mode I did follow all the manual removal steps of uninstalling ZoneAlarm from my system and registry. I think my hard drive is not damaged since I can boot into safe mode with no problems and I've successfully run chkdsk /R on all my partions. I was going to post my minidump file but I have no minidump folder anywhere on my system? Since it's W2K I checked c:\winnt\ for the minidump folder but couldn't find it and the did a search of all my drive but still found nothing. Should I do the suggestion of the first post of this thread: How to: Repair Windows XP/2000 if you are unable to boot into Windows. ??? At work I'm also running W2K pro and I could copy my "C:\WINNT\system32\drivers\ntfs.sys" file and try to replace the one on my home computer if that will help? I also read in a post about doing a 'fixboot' and 'fixmbr' from the Recovery Console, is that an option I need to try? I just want to get back to normal without having to reformat or loose any data. Thanks for any advice, I'd really appricate any help.
