Bootmgr is missing

[scruffy0402]

So I finished moving all my parts into my new 750d,everything was working fine for a few hours. I restarted it once after updating my gpu drivers and got the bootmgr is missing screen. A couple forums say all you need to do is repair it through a bootable USB for Windows 7,and to boot from it and click repair. When I try all the steps it doesn't show my os in the list of Windows installs on the computer so I can't repair it =( i have 3 ssds and 3 hdds, so I'm assuming that's the problem and I just have to unplug every other one except the primary boot drive but I wanted to ask before I try that.

Edit: luckily I tried it while waiting and it seems to have worked =) will update post if I have any other issues.
