Linux Limbo - Bootmgr missing for dual boot
 
Well good evening,

OK, I have a Fedora / Windows 7 dual boot machine. I went to a website that explained how to do it step by step with pictures. Except now I can't boot back into windows, which I need for work. I installed grub but don't know how to find it or set options. (Total Newb) Windows recovery sees my installation but tells me that there's no problem with it, and I can find files in an image. (yay)
When grub comes up it offers me boot choices, but Other takes me to a screen that says, "BOOTMGR is Missing" Ctrl-alt-del to restart

Any Ideas?

Thanks in Advance,
Bob

This seems to be a windows error rather than a Linux or grub issue. Grub is taking you to windows boot but it is somehow missing the loader. Not sure how you managed to do it.
You can try to restore the windows boot manager from the recovery media and then reinstall grub again properly.

I am somehow double posting everytime I post....

Went to the recovery media first. Have run it several times, it says there's no problem loading windows. Ecxept, there is. ;) Gr8 minds think alike though, any other ideas anyone? Is there a linux tool for recovering boot partitions on windows?

Probably just pointing to the wrong Win partition - in Linux, go here, get and run the script and post the RESULTS.txt
That way we can see the actual boot setup on your machine (no personal data).

OK, that was tough. Apprearently I'm not a sudoer ???

Thank you,

By default Fedora doesn't use sudo. As root add these map lines to /boot/grub/grub.conf (note there is a space in there)
