Note: This has been tested with Rocky Linux 10 and Red Hat Enterprise Linux 10 installed from GA ISO on a Proxmox 8.4.5 Host.

This is the host:

When I install an Enterprise Linux 10 VM in EFI Mode, grub2 seems to be unable to find the EFI loader.

The VM configuration is

and the installation layout

When I hit F2 and select the first entry from the EFI Boot Manager, the grub2 boot manager loads, showing the menu and sucessfully boots into the OS.

This behaviour is known to me with VMware vSphere where you need to set efi.quickBoot.enabled=false but I can't find a setting like this for Proxmox.
Does anyone know about this issue and got a working solution / workaround?
 
so your ESP is on one disk, and / on another (why?)? did you add both to the list of bootable disks in the VM options?
 
I did this because I follow my very personal philosophy that each mountpoint gets its own virtual disk. However, removing scsi0 from boot order leaving scsi1 fixes the issue. Also, not using a dedicated vDisk for ESP also works.

So for me this looks like an issue with the installer and is not really related to Proxmox.

possibly. could you try reproducing with Debian as VM OS? if that is also affected, it might be some issue with the UEFI setup of the VM. if that works, then it does seem like a bug in the redhad/rocky linux installer or grub packaging..
 
Okay, so I tried with debian-12.11.0 exactly the same way and it's exactly the same result. Maybe you need to investigate this in QA ;)
