VM Fails to start: "Failed to start Boot0001 "UEFI QEMU DVD-ROM"" - GPU Passthrough VM Config Setup

[KingTChoka]

[SOLUTION] So I re-created the VM from scratch using those machine config values below right away, and it seems to have worked! Whereas the error below occured because I originally created the Windows VM as usual (using seaBios, KVM CPU etc...) and then I tried changing those to the values below. So the solution perhaps is to create the VM from scratch properly the first time, instead of trying to change it later.

[ORIGINAL]
Hello,

My Windows 10 VM fails to start. I'm following GPU pass through guides (Reddit, Youtube).

The error I see is exactly the same as this post but their solution of just 'disabling secure boot' still doesn't work for me.

<The error>


<Pressing 'Esc' repeatedly to enter some TTY, then typing 'esc' to enter the BIOS of the VM>

<Secure Boot Config>

<Boot order options: windows was manually selected following this guide>

<VM Hardware Configs>

Any ideas?

Thanks!

So this is the 5th topic i find in the Proxmox forum related to the problem of booting non-linux iso in a VM.

There is also this: https://forum.proxmox.com/threads/unable-to-boot-ovmf-vm-on-proxmox-6.60424/
This: https://forum.proxmox.com/threads/unable-to-boot-ovmf-vm-on-proxmox-6.60424/
this: https://forum.proxmox.com/threads/help-failed-to-start-boot0001-uefi-qemu-dvd-rom-time-out.83521/
and others.
Is the first time i see Proxmox team not having a clue of what is the problem.

Let wait to see if some Premium Staff Member can solve this.
I'am having the same problem trying to boot a MacOs image.

Unfortunetly all the intents i had failed.
Maybe you could try to boot from the BIOS of the VM

Try with a non-hacked legit Windows ISO which supports UEFI
