I had a running Proxmox server, booting via zfs raid (systemd).
After adding an nvme drive into a pcie slot, the system tries boot from that drive.
I see the proxmox bootscreen but when selecting Proxmox to start, then my server jumps to the nvme drive.
Can I change this without reinstalling the server?
 
figured out by my self:
After reinstalling it didn't go better - still boot errors indicating problems with pcie and nvme.
So, I analyzed my BIOS settings, after changing the pcie settings from auto to pci express 3.0, everything works as expected.
