Unable to install Proxmox VE 6.1 on zbox ci329nano

[_the_]

Currently I am trying to install PVE on my ZBOX, but it always fails on the last step, configuring GRUB with
failed to prepare EFI boot using Grub on /dev/sda2: unable to install the EFI boot loader on /dev/sda

The console on (ctrl+alt+f2) does not show more informations about that error

Any hints here, how to correctly install the bootloader?

Thanks in advance

hi,

if the installer detects UEFI, then it will try to install EFI + systemd-boot
otherwise it will default to grub

maybe you can check the BIOS settings to see if you can enable/disable UEFI support and see if that changes anything

The BIOS shows me several options for UEFI
pure UEFI (default)
UEFI compatible
legacy

With pure it fails to install grub here. Also what I have seen SecureBoot was enabled.
It also fails with pure without SecureBoot with the same error.
Will keep you updated with the other BIOS options

in UEFI compatible it ends up with the same error as before.

with legacy it works.
