Does not start after mainboard replacement

[eddie84]

Hi everyone, I changed the mainboard, but the UEFI boot no longer starts, it doesn't appear at all. Using the Rescue mode of the ISO it starts normally, I see all the contents and all the VMs. How can I recover the boot without the ISO?

Thank you

It seems like the UEFI NVRAM on the new motherboard does not have a boot entry for PVE yet.
You can generate one with:

grub-install

if you are using GRUB as the bootloader

You can check which bootloader is configured with:

proxmox-boot-tool status

But the easiest way that should work would be to change the boot order in the firmware settings so that the disk with your PVE installation is the first option.

This just means that you are not booting with proxmox-boot-tool

how can I solve it?

root@pve:~# efibootmgr -v

root@pve:~#

the mainboard read this:

Boot0001* Windows Boot Manager  HD(2,GPT,04585bf7-335d-4af9-aee9-99e9ac88cb0d,0x800,0x200000)/File(\EFI\Microsoft\Boot\bootmgfw.efi)..BO

I think the solution is to delete the boot0001* or change the bootOrder

 

[eddie84]

I'm trying to both delete the boot with the command

efibootmgr -b 0001 -B

than to change boot order with

efibootmgr -o 0000,0001

takes command from shell

I restart but nothing changes, it always returns as before as if it didn't write the command to disk

the same problem, but my boot0001 is UEFI OS, when i efibootmgr change boot order and reboot pve, it will reset to previous state.

everytime when i reboot i need to setup BIOS Boot order to proxmox...
