I have two drives with two different OS on them. Win 8 on my old HDD that came with my computer, and Win 10 on my SSD. When I originally installed my SSD OS, it worked for some time, but eventually I had an issue where it was not detected and I had to reinstall Windows 8 for reasons I don't entirely remember. This is where the dual boot issues began. Now my BIOS has trouble detecting which OS to boot up. Basically now the only way for me to boot into Windows 10 is to press F11 and choose my SSD manually as the boot drive. I've tried basically every boot order in my BIOS but it will not let me boot without F11.
So basically I want to remove every trace of the old OS. I formatted the drive but there is still a UEFI System Partition on it that I can not delete. There are also faded out folders on my SSD pertaining to the old OS and User accounts from my Win 8 install. How do I delete those? It keeps saying I need permissions that I do not have since I'm booting from Windows 10.
I purchased a new HDD today that I can use to store my files. Part of me wants to just throw the old HDD into the grand canyon, but if I can remove the old drive completely so that I can boot into Win 10 with no issues, I guess I could keep the old drive as another storage unit.
Any help is appreciated. Thanks!
