Proxmox advanced options not visible

[Syntax3rror404]

Describe the bug
You can choose between normal, text and debug. With the proxmox iso used the normal way a white screen comes up with advanced options. This is crictical for the rescue part of booting a broken installation.

It looks like netboot is skipping this white screen.

The other way to solve this is, by adding a additional installation method for proxmox for rescue boot.

To Reproduce
Boot and missing the screen

Expected behavior
You can see the white screen and choose what you want
