Bootmgr is missing after computer crashes

I was on youtube when all of a sudden, firefox froze and my computer then crashed. After it restarted, "bootmgr is missing" popped up. I tried a repair disk but it didn't work.

Any suggestions?

If you have the 7 dvd try booting to the repair tools and open up a command prompt there. Simply typing in the bootrec commands should get you back running again.

The "bootrec /fixmbr" and "bootrec /fixboot" once you have typed in the "bootrec /ScanOS" command would be the two used there. As far as the Startup repair tool sometimes you simply have to give that a second or third run in order to see it finish fixing the problem.

It still says "bootmgr is missing" after I did the bootrec commands a couple of times.

OUCH! Have you tried running the Startup repair tool about 2 or 3 times? That might get you going again running the automatic tool option.
