Experiencing strange disk behavior where the PC will not boot to the M.2 drive, if it is selected as the boot drive in the BIOS. If I disable it in the BIOS, it boots.
It's a 'Samsung 950 Pro M.2 512GB PCI-E 3.0 SSD'. MB is a new ASRock X570 Phantom Gaming 4.
With the M.2 disabled in the BIOS and booting/working, I then tried to add an SSD. The SSD (Samsung 860 Evo series 2.5" 500GB SATA III) gets recognized in the BIOS, but the system will not boot, and will not recognize the M.2 drive in the BIOS at all. Both drives were clones; the M.2 drive was cloned from a bootable SSD as an upgrade (SSD to M.2, more capacity, SSD replaced with a high capacity SSD) using Acronis.
Appreciate any suggestions.
