Bootmgr is missing.

I am attempting to fix the BootMGR is missing, but have ran every bootrec.exe /command they offer, plus the startup repair gives me the error that it cannot be repaired automatically.

Any suggestions?

Hi,

I assume you have one drive and one operating system. Don't know what caused your problem, but if you are not too curious and just want to get back and running, a repair install could be the answer.

This should replace all the Vista files , without damaging your own programs and settings. You need the proper MS install dvd to do it.

Hope it helps

I had this issue a while back.

You can try to do either;

• Startup Repair (Recommended)
• Offline system restore (Advanced)
• Reinstall (Last Resort)

Even Startup Reapair fail there is another way to repair:

Boot DVD Vista

Choose language>>repair computer>>command prompt and type:

bootrec /rebuildbcd

Hi rossroth,

there is also step 4 here, if you are comfortable with it

I had the exact problem. My computer was working perfectly fine last night, and when I woke up, it had a black screen that said missing the bootmgr. I did a lil search online and followed a couple of instructions. Non of them worked for me.... I finally found out that the computer wasn't recognizing my Hard drive. I have two hard drives, One for boot windows OS, and the other for extra space (pic, vid, mov, games)...
So I guess that this goes for the people who have extra hard drives and have the message that says: bootmgr is missing...
Go into bios and make sure your booting from your CD: first and then from your Hard drive. Then make sure that your bios recognizes your main hard drive. If it does not, then disconnect everything from your computer. Open the back and make sure that all the wires are properly connected to your hard drive. If you have SATA cables connected to your hard drive, make sure that they are not bent. The bent causes the motherboard not to send and receive information from the hard drive. I would recommend to unplug both, the power and sata cable from your hard drive and just reconnect them. That is what i did and I restarted my computer and WHALLA, it worked... Thanks for reading!

Had the same here. Bootmgr missing. Tracked it down to a bad sata cable. removed cable and reconnected it an all was ok for a few days then the same happend again.
Now I have bought better sata cables and all is ok.
Hope that helps.

These commands are appriopriate for XP not for Vista
For Vista are following equivalents:

bootrec /rebuildbcd
bootrec /fixboot
