Hyper-V Gen2 Debian -> Proxmox

[carrer]

Hallo there,

i recently imported Hyper-V Gen2 to Proxmox (UEFI).
At bootup the machine will drop to uefi shell and i can start via:

FS0:\EFI\debian\grubx64.efi
FS0:\EFI\debian\shimx64.efi

When i try to add this as fixed boot from file in the UEFI Setup (hitting ESC startup) i cannot save this configuration using F10. It will accept F10 and save it but the setting will not persist the next start.

Secure Boot is disabled in Proxmox and was disabled in Hyper-V.

What can i do?

Thanks!

Found a solution, that seems to work, yust copy FS0:\EFI\debian\grubx64.efi to FS0:\EFI\boot\bootx64.efi.

Make sure you have added an "EFI Disk" to your Proxmox VM. Otherwise BIOS settings won't be persisted.
VM -> Hardware -> Add -> EFI Disk
