Pc has 2 NVME drives, 1 ssd, 1 sata.

Only one drive is set as boot windows manager, and only 1 drive is set as PRIORITY BOOT, one of the old NVME once had windows on it, but i formatted it completely . My pc boots, shows a black screen and doesnt go into windows, only after i hit the reset button does it reboot normally into windows.

What is the reason for this ?
this is a high end gaming pc
