System Couldn’t find and bootable devices

[gteergaming]

I just built a new pc but decided to keep my storage (Samsung 850 Evo) BIOS detects the drive but it doesn’t show up as bootable even though it worked fine in my old PC. I can no longer test it in my other pc as I also used the power supply and don’t want to take out my psu and put it back into the old pc. If I could get any help on what is causing the no boot drive found error it would be a help as the drive has all of my files. Motherboard is Asus Maximus Xi Code if that matters.

That's why most advocate clean OS installation on a new system. That's even more important if you are switching from legacy BIOS to UEFI. See if you can locate CSM setting in the BIOS, enable or disable it and see if that helps.
