Can't boot after xp sp2 install
This is a long story so please bear with me,
I can't boot anymore after I installed sp2. I have a home built athlon64 machine w/ xp Pro. I can't boot into safe mode or nothing. The machine freezes after trying to load "Mup.sys." and dies with the error: STOP C000021A (Fatal System Error) The session manager initialization system process terminated unexpectedly with a status of 0xC000026C (0x00000000, 0x00000000). The system has been shut down. I've tried renaming Mup.sys and it fails on the driver before that (vmodem.sys). I don't know what the driver would be after Mup.sys but commonly (I think) it is agp440.sys which I renamed to no avail. Based on my research I don't think it had anything to do with Mup.sys or a driver. In the microsoft KB there is info on STOP C000021A but the status is not 0xC000026C. I have not found a solution and I liked the idea of uninstalling SP2 through the recovery console, as per the MS KB. I get there but there is no $NtServicePackUninstall$ directory!! (I wrote the background at the end of the post which points out that the machine thought SP2 was installed succesfully). My question right now is how can that be???? There are many $NtUnistallKBxxxxxx directories with the date stamp of the night of SP2 installation but no $NtServicePackUninstall$. Any suggestions on why this is and how can I get rid of whatever happened (e.g. spuninst.exe each of the hotfixes???) I'm trying to do everything short of a repair install so any ideas are appreciated. The Background: Initially I installed sp2 through automatic updates. At the end it complained that the installation failed and it had to uninstall the SP (that "items ... manifest ... verification ... failed ..." crap). So it uninstalled and reported that "Windows may not work properly." I got lucky and windows booted and seemed to work fine. I researched this and found many recomendations to avoid the automatic updater and downlaod the full (272meg) SP2 file and install from that. Stupid me (slap myself), insisting on installing sp2, went ahead and did that (download + install). It said that the installation was comleted successfully. Now I can't boot at all anymore (safe mode, vga mode, last known good mode, whatever.) I have tried removing both cdrom drives, and my crappy (not MS certified) modem. I don't have integrated video so I can't remove the NVIDIA video card. I'll try removing the sound card tonight. Enough rambling from me and thanks for your time. |
