Making a VM with 2 operating systems in proxmox

[Santig]

Hello everyone

I am trying to create a VM with dual boot (Windows 11 and Ubuntu 24.04). The VM will be used with a fog installation to deploy to a group of computers in my organization.
The problem I am facing is that when I boot Windows through Grub, it shows me a static screen (as seen in the image), but if I boot through UEFI, it allows me to enter Windows correctly.
I would appreciate any help, i am a bit of a proxmox novice so plz be kind.

For anyone that sees this thread, I would recommend using a refind as grub
In my case it solved this problem

I'm not sure why you go for dual boot there, and not just use a different VMs, imaged with each OS? To have a single FOG procedure for users?
In the physical world, that may make sense to avoid redeploying to switch between OS, but on a VM?

Also, FOG (or clonezilla) is fine, but you'd probably gain a lot by using a template and a linked clone.. especially if that's for training purpose, just saying!

maybe you should try switching grub from graphical to textmode (GRUB_TERMINAL=console)

i have seen such issue when grub was in graphical mode.
