As Microsoft advise / Windows Server 2022 isn’t Legacy BIOS compatible anymore, i have to set up a brand new template using UEFI.
However, if i tick “EFI” and Secure Boot from VM configuration or not, I can’t boot on my ISO at all. It still go to EFI Shell or in the UEFI Menu.
I also tried to update VirtIO drivers directly into my Windows image (on install.wim and boot.wim on all indexes) but i can’t go so far in the installation part.
Does anyone was able to use EFI settings with Windows Server 2022 ? If yes, what was your settings ?

Is it in a boot loop? Boot from iso → reset → boot from iso → reset etc etc
Workaround for me is to add cpu_passthrough=true via cli to the vm.
Actually i found out that i have to add VirtIO drivers to Windows Server 2022 iso (to every index of boot.wim and install.wim). By doing that, everything went well and i can boot on the image easily without error.
how did you do that?
Follow the steps in that article https://thunderysteak.github.io/windows-setup-driver-injection and don’t forget to add drivers in every indexes of boot.wim and install.wim
Once you’re done , you can upload the new ISO on Prism Central and properly boot on, with UEFI settings enabled :)
