Recently, I upgraded my CPU which required a mobo + ram upgrade as well (was running ddr3 prior). I took out the hard drives and SSD setup I have. On my old computer, I had 1 SSD (256GB) with the OS and other useful applications, and 3 TB worth of HDDs. I have an ASRock b550 phantom gaming mini-itx. I took the SSD's and HDD and plugged them into my newer updated build and whenever I go to launch into windows it gives me an infinite loop of Attempting to repair (where it does nothing) and then restarts and just shows the ASRock logo. I then attempted to get some bootable media (USB with Windows 10 installer to repair). This did not work as when I plug it in it does the identical thing where it just halts at the ASRock logo. I don't know if I'm booting incorrectly with UEFI vs traditional legacy bios. I just want to game on my upgraded computer. Any help would be greatly appreciated.
