Greetings,

Like many others out there having difficulties, I'm trying to pass a GPU through to Windows 10, i have been at it for a couple of days and have remained unsuccessful. I continuously keep arriving at dead ends where others will discuss or point something out, The version VE 5.3 I'm using doesn't appear to work the same.

Lets start out with the Main guide that is commonly pointed to: https://forum.proxmox.com/threads/gpu-passthrough-tutorial-reference.34303/

I get to this step -> then run update-grub
I can proceed no further, as that script does not appear to exist in this installation, I let WinSFTP do a search of the entire server and still didn't manage to find the script.

So I also heard that before you can do it that UEFI BIOS has to be installed, Have been working on this with absolutely no luck whatsoever. I get to the start screen, press ESC, enter the BIOS and no options appear to work, is there a clearly laid out tutorial somewhere? I assume I'm trying to Boot the CD-ROM Image 1st? That does not appear to register, And when trying to change the Boot order in the GUI under "options" there appears to be no particular effect either.

In the New 5.3 it is stated that the Passthrough can be added from the Gui, Using an RX570 card but when selecting from there it recognizes an RX 470/480i, I try adding it to the hardware and starting and from there no matter whichever Display option I use i get a "can't lock file '/var/lock/qemu-server/lock" error and proxmox freezes up forcing me to reboot the server.


I have tried various others, but I will keep it short, as the biggest issue is passing through the GPU, If i could get any assistance on how to approach this and what steps I should be taking would be much appreciated. I also want to mention I have in fact managed to Install Windows 10 Just fine without UFEI or Passthrough.

sounds indeed wrong, it is part of the grub-common package which we depend on indirectly, at should be located at "/usr/sbin/update-grub".
How do you do things on the server? I'd try the web interfaces shell if you do not have access to a real SSH client.
Also, how did you installed Proxmox VE?

To let a VM boot with an EFI firmware instead of SeaBIOS you would go to VM -> Options -> BIOS (edit), then select OVMF (UEFI), additionally add an EFI disk (so that EFI can store it's config persitently) in the VMs Hardware tab.

Much appreciated, I installed via USB with the package from the Homepage. I got the issues resolved by installing Debian 9 first then Proxmox on top of that :) All the typical commands began to work.
