[SOLVED] System unbootable - grub error: disk lvmid not found (when pluging in new disk)

[Loulou91]

On my NUC I installed last version 7.4-4 on a SDD M2 1Tb without any problem. Then I plugged an additional internal disk SSD 1To containing 1 partition eFAT filled under windows 11.
But no more able to boot. I got the following error:

Welcome to GRUB!
error: disk `lvmid/........./............` not found.
grub rescue>

I tried the following fix (last section) https://pve.proxmox.com/wiki/Recover_From_Grub_Failure but unsuccessful.

If I remove the additional disk boot is ok.

Other point, the additional disk looks correct. I tried to plug it into proxmox using usb and the access was ok!

Any idea?

I solved the issue... I inverted the use of the 2 disks and no more problem.
It's more a workaround than a solution I guess...
