Hi All,
I have a laptop which does not support UEFI, although having CPU with 8 threads.
Install 6.1 in Buster was not successful, could you please advise what is the last version that still could boot without UEFI so I can start installing from it and upgrade up?
Thank you

PVE does not need uefi, what exact problems/errors did you encounter?

My steps are:
a. downloaded Proxmox ISO for 6.1 from https://www.proxmox.com/en/downloads
b. created USB boot stick from MX Linux (most probably a dd)
c. try to boot from created stick in XPS L702
d. results in "operating system not found"

The laptop has Debian Buster which I installed yesterday from a Debian ISO, using MX Linux USB maker (same flow).

No experience on these things, but shouldn't we have another entry for 64bits like we have for i386?

I installed from DVD. System installed 6.1 but did not boot.
On fdisk it is showing a EFI partition.
Therefore I have to disagree with you. Proxmox VE 6.1 supports only UEFI.

In what mode is the BIOS? Does it have a strict BIOS, legacy, non UEFI mode?

the BIOS on my XPS L702x does not support UEFI.
I am now trying to install from Buster on a Proxmox VM on another machine. Due to having it in Proxmox I will be able to send you messages if it does not work.
If the installation in VM with Buster 10.2 is successful, I will perform same on the laptop.
thank you

Installation in VM was successful. On laptop it was not. I have below error:
Code:
/etc/pve/local/pve-ssl.key: failed to load local private key (key_file or key) at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 1713.
Any ideas?

Is it possible that the disk you are trying to use has been used anywhere else?
An EFI-partition can be a left-over, causing you now trouble. Upon my experience the first EFI partition is sometimes hard to get rid off - for whatever reason.
You can try to do a DD from a live-DVD onto your disk from /dev/null to the disk itself - maybe that helps.
My system does not support EFI at all, and I have recently installed/upgraded Proxmox to the current release.

the installer creates an EFI partition to allow switching to UEFI later on without re-installing. that does not mean that it requires UEFI support..

Hi, I encuonter this issue too. I my case, I have to add "vga=normal" into boot menual kernel line, otherwise the installation will fail to initilize. And I found I can only initilize the installation when BIOS using Legacy model, If BIOS using UEFI model, installation also fail to initilize even I modify the kernel line. However, even I installed successfully(I am using ZFS RAID1 with two 8TB disks), my server still failed to boot, it seems can not find the boot harddisk at all, I must change the BIOS to UEFI model, then my server can boot from disk, but then Proxmox boot stuck at (initramfs):
