I have this exact same problem on an AB350 Gaming-ITX/ac, also using an OCZ RD-400 256GB M.2 SSD.

It boots normally from a cold boot, but displays the same "Reboot and select proper boot device or insert boot" message if I reboot from Windows or by pressing the reset button. Additionally, when it's in this state, it's not even recognized in the BIOS as a drive, which makes me think it's not a Windows issue.

However, if I fully shut the system down, and then do another cold boot, it suddenly, and magically, shows up as a boot device and boots Windows 10 normally again. I've tried it with both the generic Microsoft RD400 driver and several versions of the OCZ driver. 

Though again, since BIOS doesn't even see the drive during a reboot, I seriously doubt it's a Windows problem. It's something with the board itself.

Dear Faolan,

Greetings, this is ASRock TSD.


According to your question, we provide some suggestions for you to check the system.
 
1. Please enter to the BIOS setup and then check if the M.2 can be detected under Advanced >Storage Configuration.
 
2. Under BIOS Boot page, please check if the M.2 can be detected in Boot Option or BBS Boot Priorities.
If the M.2 is detected under Boot page, please try to set the Windows Boot Manager to Option#1.
 
3. Please install M.2 SSD to other M.2 slots to verify.


Thanks!

All the best,
ASRock TSD
