Windows 7 Ultimate (Bit unknown)
I changed the active partition to one without an OS!

I was trying to get my second hard drive working by setting the active partition using diskmgmt.msc , then malware bytes decied that it was SOOO important , and restarted the computer. I got a system repair disk, and tried bootrec /fixboot (nothing) and bootrec /rebuildbcd

Scanning all disks for Windows installations.

Please wait, since this may take a while...

Successfully scanned Windows installations.
Total identified Windows installations: 1
[1] D:\Windows
Add installation to boot list? Yes<Y>/No<N>/All<A>:Y

(something like)-> could not find what was requested

Lastly, it's windows 7, when I launch system repair on system repair disk, it can't find the OS

Help please.
