Blackscreen after installation mode selected (in bootable USB)

NethServer Version: 7.9

Hi everyone,
i’m looking for to install nethserver on this server:

  • Intel i7 11700K
  • Asus ROG Z590-A
  • 16 GB of Corsair RAM

Sadly i get a sad blackscreen after every installation mode selection.
I created the USB from my Mac with both: BalenaEtcher and dd command methods, but problem persist.

This solution seems so … stupid: Bootable USB doesn't show up / blackscreen after installation mode selected
Why doesn’t work for me?

Maybe related to this:

IIRC rocky linux and/or almalinux do backport from centos 8 what is needed to support newer cpus. It was CloudLinux.
Support for Rocket Lake CPUs was added in Kernel 5.10 or 5.11

A workaround to have nethserver on this hardware could be install some virtualizer.

Can you try adding a cheap video card and see if it works with that?

“Cheap video card” since 2020 seems quite a unicorn … :wink:


@andreapellegrin any news?

Hi @andreapellegrin,

I have an ASUS with i7-7700K @ 4.2 GHz and I had trouble with the display using standard BIOS so I switched to UEFI and now all is working fine.

F2 to get to the BIOS to change to UEFI.
