Am in really deep trouble here and would use every advice available from everyone out there..

Am message just pooped on my screen and i had to restart my laptop. upon restarting the BootMgr got corrupted.

Am running Windows Vista 32 bit by the way..

i got onto Google with a friend's PC and found two basic ways of fixing it. the first one that requires windows to automatically fix it using Startup repair ends up with the error message : "Startup REpair cannot repair this computer automatically"

the second option that requires me to rebuild the BCD scans my system and finds the operating system on drive D:\Windows which i believe should be C:. if i hit Y(yes) for the rebuild process to take place i get the message "The required system device cannot be found"

i then try the second option which requires me to recreate the BCD Store ends up with an error message that says "The store export operation has failed. The requested system device cannot be found". proceeding from there is meaningless since the system device cannot be found.

I somehow believe the device cannot be found because its identifying the windows installation on D: instead of C: but how to change that i have no idea... I dot know how it happens to identify an O/S on D: when there's none there...

How do i go about fixing the BootMgr? I have very important files on my system and cant afford to reinstall windows... i really need to fix this..Please help...
