Evaluating ProxMox and failing on UEFI

[ilian_nilsson]

Hi,

I'm trying to get ProxMox onto a laptop to evaluate it.

Every installation attempt fails on UEFI.

I can't fall back onto BIOS because the computer does not have it.

Error: proxmox bootloader setup errors failed to prepare efi boot using grub on /dev/nvme0n1p1 unable to install the EFI boot loader dpkg-divert warning please specify "--no-rename explicitly.

Well there sounds to be a solution but I'm not smart enough to utilize it.

I'ts an ASUS ZenBook NAN0CV05K957426, UEFI Ver: UX5401ZA.304

Any toughts?

Welcome, @ilian_nilsson
In the meantime you can try installing Debian there - as a test to know if this is Proxmox-related or a more general problem.

the likely culprit is a pre-existing filesystem on your local drive. The installer is usually pretty good at dealing with it, but in your case clearly it isnt.

use a linux livecd like https://gparted.org/download.php and completely wipe the drive; retry installation.

Hi Everyone

I m trying to install proxmox in my DELL Poweredge R720 i have the dell perc H710p mini installed

so i have a raid 0 on 2 intel ssd's and although i managed to installed it the first time without any errors
i broke up the raid to install it directly on my drives but that did not hapeen since my hardware raid controller does not support mba mode
so i created the raid 0 again and whenever i try to install proxmox i get this error (see attached)

anyone has similar issue or can help ?

thanks
