Windows 7 Bootmgr is missing (failed install)

Today I went about building a new PC using some old parts (GPU/RAM) from my last PC. Everything went fine, it boots up and I get to the BIOS. I started the OS install to my SSD and everything is fine until I get to expanding data. At 10% it hard locks (nothing progressed, mouse wouldn't move) so I reset.

This is when I found at the heatsink fan wasn't rotating (yes I'm an idiot) and it was due to it not being totally uncoiled from the heatsink itself (stock intel heatsink).

It boots up again everything works fine but now I get a bootmgr is missing error. I mess around with things nothing works, tried dban but didn't work will try again when I get fresh CDs.

I then tried putting in my old HDD and it loads up until the Windows is Loading screen then BSOD for half a second and restarts.

So where I'm at currently is the SSD needs to be wiped as it probably has fragments of a failed install causing the bootmgr is missing error. But also I'm guessing I have bad RAM due to the BSOD when starting up with my old HDD. I may try just loading my old HDD with one stick of ram and see how that goes. I'll also try memtest.

All in all I'm quite lost and don't know where to go from here which is why Im here.

As a side note here is my build

  1. Best answer
    try restarting install from install media (make sure bios settings look to boot media(cd or usb drive) before the hard drive) and make sure you delete the failed install partition (or if nothing needed at all the hard drive let windows install reformat the whole drive)
  2. I tried that and it gave me the same result. I decided to just install the OS on my HDD I was gonna use as the secondary drive. I guess my problem now is to figure out how to use my SSD along with my HDD and eventually move my OS t the SSD.
  3. just wondering did you have both drives installed at the same time while trying to install windows. if so disconnect the hard drive and only have the ssd hooked up when doing the install. and make sure that the ssd is set as the boot device after you hook the hard drive back up after installing windows on the ssd.
