Once I tried to do recover default vista settings as I was getting lots of problems. I did a Vista DVD boot and later I found some eroor cropping up. Then I tried to boot again through vista DVD but I am getting a "bootmgr is missing" and Press CTL+ALT+DEL to restart. Now I am not even able to boot with vista DVD again. It gives me again the dreaded "bootmgr is missing" and Press CTL+ALT+DEL. Please help
