DVD ISO UEFI boot not working with Proxmox 8.0.3

« on: July 15, 2023, 02:58:46 pm »

Hello,

I have tried to boot the DVD ISO installer in UEFI mode when creating the VM for OPNSense on my Proxmox server and I've noticed that only Legacy boot is working.

Steps to reproduce :
Try to boot the DVD ISO in UEFI mode from Proxmox 8.0.3 using a VM in UEFI mode.

Older Proxmox and OPNSense ISO files do not have this issue.

Thank you.

It works if you don't create an EFI disk.

Disable Secure Boot before the VM or install.iso starts.
