I had Windows Vista installed (C:) and then I decided to try out the new Windows 7. I created a new partition (D:) and then preceded to install Windows 7. I selected custom install and went through that process. Windows 7 booted up fine and everything was working. Then, ignorantly, I decided to go back into the Disk Management and I saw that Vista Partition (C:) was active, and the Windows 7 Partition (D:) was not active. I decided to make the Windows 7 partition active.
Upon restarting the computer I get the error message "BOOTMGR is missing". I am pretty sure this is just related to the fact I made the Windows 7 partition active, but I cannot for the life of me find an easy to solution to put the Vista (C:) partition active again.
I tried using Gparted, but the GUI would just turn my screen black. I then tried using the recovery console from Windows XP CD but I wasn't sure if it had the ability to make partitions active. I do not have a Windows Vista CD.
Whats the easiest way to fix this problem? Setting the C: back to active would fix the problem? Or do I need to fixmbr or any of those others things.
Boot to either vista or W7 and use the repair feature.
"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

I am having that same problem Brian....so Jefro, are you
simply saying that we can boot from either Vista or W7 disk
and then just repair it, and upon booting correctly just going
into disk mgmt and changing the active hdd?

Hey, I have the exact same problem as Brian, and not being an expert in computers, i have no idea how to fix it. I tried putting "gparted" onto a usb, but it shows as an invalid system disk. I also tried running fixboot, but that didn't help either. How can I reset the older disk to active.

If you could borrow a Vista CD, then you could run the startup repair which would probably fix your problem. Also, if you installed Windows 7 rom a DVD, try booting to that DVD-maybe there's a startup repair option also. Then you could get back into Windows 7 and change Vista back to active.

But you said that you had Vista installed, so i thought that you might be able to get hold of a Vista DVD. Did you try booting to the Windows 7 DVD to see if there is a startup repair option ?

Yes, nothing. I've tried using Gparted through a live USB but that gave me a "boot error" after a few hours of worthless effort. I tried using fixboot, which created a boot sector but only changed my Bootmng missing to NTLDR missing. Then I tried to copy the ntldr and ntdetect files but it said access denied. Oddly, instead of c:\windows> my recovery console shows c:\>. I am a novice person around a computer with no idea what he's doing, and this is turning out bad. I am no longer able to press f2 to access my bios or ctr + alt + delete to shut down. My problem started out precisely like the first guy, only instead of Vista i was using XP. Does anyone know what i should do?
