fltmgr.sys failed to load on startup

Hello,

I had no problems yesterday or ever before. Apparently there was an update last night, and since then my desktop won't start up. It gives me the error saying windows\system32\drivers\fltmgr.sys will not load. I did a system restore to the system checkpoint before that update last night - to no avail though. I've done the automatic startup checker twice using the vista installation disk, it says there aren't any problems. is there anyway to just replace this fltmgr.sys from another vista machine? Or am I just stuck?

there has to be some kind of fix! thanks!

UPDATE:
looking through the startup recovery log I found this:

Boot critical file: c:\windows\system32\drivers\fltmgr.sys is corrupt.

Repair Action: File repair.
Result: Failed. Error Code = 0x490

also - won't boot to safe mode, same error. last known good configuration doesn't work.

OK, Here are a couple of tutorials to look through to help try and get tyour system up and running. I listed them in order of preference. Hopefully one of these will work for you.

Good luck and let us know what happens.

hey Sygnus!

Thanks for your reply. I've actually already tried all these methods, nothing has worked. Eh, not all - i'm trying to avoid the reinstallation of vista as i'm on a domain here and the repair install doesn't remember all the information so it winds up being a major pain.

I guess i'm just wondering if its possible to copy over that fltmgr.sys with one that works from another machine? If so, how would i do this? is there another program i can burn to a cd that'll put me in a command prompt and also allow me to copy a file over to the hd?

thanks again!

update

when i try the sfc /scanfile=c:\windows\sytem32\drivers\fltmgr.sys it says
"windows resource protection could not perform the requested operation"

i read somewhere that i have to be in the elevated command prompt - i can't boot to windows, not even safe mode, how can i do this?

it seems that the windows updates that required the 3am restart were:
KB905866
KB959634
KB960715
KB961260
KB890830

however, i did a system restore using the vista installation cd to 4 days ago and it still doesn't come up.

Unfortunately, I can't say whether this will work or not, and it would be a complete guess on my part. Perhaps someone like Brink can chime in here?

I just posted those links to give you some ideas and hopefully get some other members to chime in here as this is not really my area of expertise.

Sorry

Again, maybe Brink can help you out here. Look him up.
