Error when install proxomox v8.1.2

[Nath2692]

Hello,
I have a NUC13ANHi5 I try to install proxmox on it, I deactivated secure boot and activated virtualization in the bios

However, I do not have the option to switch to legacy mode.

Do you have any idea of the error that may be indicated?

The key was made using rufus and balenaetcher and I am concerned about both if you have an idea I am interested;

I deactivated secure boot

Why? and why do you want legacy boot? UEFI via secureboot is possible and should be used with PVE 8.1

I thought that the malfunction could come from there, from what I read in a procedure.
