Windows 10 won't boot unless windows 7 drive is selected to boot first
Hello
I did a clean Windows 10 pro 64bit install with a usb drive and media create tool a few weeks ago on a new SSD just for windows 10. I still had my windows 7 SSD still hooked up and set as first bootable drive when I installed windows 10 on the new SSD. For some reason now my PC won't load Windows 10 without the windows 7 drive set as the first bootable drive in the bios. I don't want to do a dual boot setup and I will be removing the windows 7 drive the PC and formatting it once I fix this problem.
Things I should note:
1. I still have the windows 10 mediacreate install USB drive that I used to do the install.
2. If I set the windows 10 drive to first bootable drive I get the "please insert bootable drive media" bios screen.
3. I tried to set the windows 10 drive to active in Disk management. When I set the windows 10 drive as first bootable drive, I get the "The Boot Configuration Data file is missing or contains errors" windows error screen when trying to boot the drive.
4. Windows 10 is set as default OS.
What is the quick and safe way to make the windows 10 drive bootable again? My guess is it involves the windows 10 usb drive and CMD?
Thanks
