Reboot and select proper boot device?

[NiKiZe]

You are using pxelinux or other syslinux variant which loads the iPXE kernel binary. This binary only supports nics with drivers in the iPXE sourcecode.

Comes from your machines bios when iPXE exits after not being able to boot, I think you have something more then just "initializing devices"
To help you further it would be easier if that full output is posted.

Another thing that is strongly recommended is to not use syslinux/pxelinux at all, especially not pxelinux, instead used iPXEs undionly.kpxe which can fully replace pxelinux.
