Windows stuck in automatic repair; Can't access BIOS/ boot menu

I've changed the boot order through both BIOS and the boot manager, as my original post stated. Neither did anything, but both were functional in the past. Neither listed the windows boot manager, either. Previously, it would boot just as expected whenever
other media was set as the first option, so I'm pretty sure there are no issues there.

As my original post suggested, I've already tried out the steps you gave. I've gone through all the options listed in the boot menu, UEFI or not.

My BIOS and boot menu settings were at their defaults when all of this started, so that's been tried already, if those are what you're referring to.

 

Boot Emergency!

No it doesnt show. Only my OS drive.

Its there and it says it running and normal.

Anyway I just had the same boot problem on reboot. Everything was fine 10 minutes ago. Now it wont boot without my manually selecting the drive.

 

Boot menu question

Hey guys I'm trying to run windows repair on my computer by booting my computer from the vista CD, problem is the boot menu doesn't detect my USB keyboard. Are there any options in bios that will make the mobo detect my keyboard in boot menu? I don't have an analog keyboard on hand so this problem is quite annoying. *Bang Head :banghead:
