[SOLVED] Don't know if this is the right area but after installing new CPU, my pc keeps saying reboot and select proper boot device.

Title. I 100% know the right drive is my 970 EVO but when I make that first in boot order, it gives me the reboot and choose different drive error. Even with I boot override it gives me errors. I have no idea what to do besides to wipe my 970 and reinstall windows?

When you say you installed a new CPU, do you mean you really just swapped one CPU for another model? Did you check the BIOS to make sure the disk settings are the same as they were? That usually means AHCI disk mode with UEFI boot for new systems.
