Hello Everyone! I hope I can find the answer to my problem here.

This is my config:
H370M-ITX/ac
intel g5400
6 x 4tb 3.5 WD drives
1 hp ex900 m.2 250gb
BIOS: 3.10/3.00
OS: Debian, Ubuntu, Proxmox. Problem is replicable across multiple OSes.

I'm experiencing a problem with NVME drive at boot. It appears that BIOS can't see NVME drive after every power cycle (not reboot, but shutdown only). This problem goes away if I hit F11 or enter the BIOS without doing anything else. I don't have to select or change anything, the only thing I have to do is to activate/enter BIOS. The problem will appear again after next power cycle.

Problem: Shutdown > boot > no nvme drive present
Workaround: Shutdown > boot > enter bios or press f11 or select drive > nvme is present

Any ideas?

Is the nvme formatted as GPT or MBR? Needs to be GPT.

It is GPT.
