I did a clean install of win 8.1 with a bootable usb and Windows somehow installed the boot partition to the bootable usb drive and not my ssd.

I hoped upgrading to win 10 would resolve this and install the boot partition to my ssd. Didn't work.

Tried command prompt and bootrec but no luck. I still need the usb drive connected to boot.

Am running mbr partitions on my ssd and computer is in legacy mode. Any help would be awesome. Thanks!
