i have discovered that the problem can only be fixed with a combination of all the posts ive read. the one above is very important. this also fixes dual boot systems that have lost vista bootmgr file. this fix assumes that fixing vista is your most important



1) make sure the only drive you have physically active(bios) is the one with vista installed. didnt matter on my system that there were 3 partitions on this sata drive and one of them had an xp install.



2) follow the commands given in the above post exactly where (c) = the drive/partition with the vista install. (this will probably not fix the problem yet)



3) now reboot your comp with the vista dvd and chose the repair option you've probably read so much about Stick out tongue



after you restart once the repair finishes this should fix your problem.



i tried everything in the world to fix mine but it only worked after completing these steps in this exact order.
