Bootmgr missing on server 2008 R2

hi guys

recently, one of our developers told me that a test server of ours was no longer working. When I tried booting, it would say 'Bootmgr is missing'. So, I inserted the server 2008 disk in and got to the repair option and selected the command prompt option.

From there, I typed bootrec /rebuildbcd and it was successful but I did notice that it came up with two records.

I typed: bootrec /enum all and noticed that it came up with two GUID identifiers; one for a C:\windows and one for C:\windows.old! I only installed one version, but it seems of course that somebody may have been messing around with things they shouldn't have.

So could this problem be occuring because we have two installations of windows? I believe the .old version is the one that was working correctly.

How can I have the .old version be the one that boots first and not the other one? That possible?

Thanks
Yashy

Your Windows is not clean installation. Most possibly the server was upgraded from Windows 2003 to Windows 2008. That's why you see two Windows folders on C:
You can easily delete Windows.old as it is not needed. Normally your old data from previous installation is copied there. So my advice is to copy out this folder and delete it from C:
As for missing Boot Manager. This happens when the partition (normally it is MSR partition) is not set active or cannot be read. You need to check the status of Boot folder and BootMgr containing partition.
