proxmox ve 8.2-2 bootloader setup errors

[maui-b]

Good day everyone. I am new to virtualization (can use VMWare, Hyper-V, VirtualBox etc. though) and want to start experimenting with bare metal virtualization. I have a very old extra PC (Lenovo E50-00) with "entry level" hardware, Celeron CPU, 4GB RAM and 500GB mechanical HDD. I dont know if the HDD or CPU is causing the error, but during the installation at 99%, I get the "failed to prepare EFI boot using Grub on '/dev/sda2': unable to install the EFI boot loader on '/dev/sda'" error. I have searched on forums for solutions but the ones I found does not solve the issue. Before I tried installing Proxmox, I did had Windows 10 on the PC and I figured Proxmox will work because it is Linux based and Linux is not resource "hungry".

Is there someone that can point me in the right direction to solve the error? If I need to provide more details, I will gladly do so.

Thanks in advance.

given that this is over 10 year old hardware - maybe its UEFI support is buggy? you could try disabling EFI boot in the system firmware and installing in legacy/CSM mode..
