i have the motherboard ASUS TUF Gaming B550M-ZAKU WI-FI AM4 with the latest Bios (2423 08/10/2021).
I installed 2 x M2 Nmve on the motherboard.
First weird problem :
In Bios screen, the 2 x M2 Nmve are displayed on main screen, but when i go in adavnced Sata, M2 are listed as "not present"
Second weird problem :
At first boot (windows 11 pro), boot on 1 x M2, the other M2 is not detected by windows, i need to process a second boot to get it detected by windows
so when i unplugg the psu (for a long time) and plug it again (corsair 750W) it is again same issue
third weird problem :
booting 2 times is ok but at third time, i get black screen, i need power off by unplugging to be able to boot again.
(notice it is not first time i get such issue on asus motherboards, but i never figured out the reasons)
Any ideas why i do have all these problems ?
