Boot Error

I have a server I would like to run with no graphics card.
I have installed Proxmox 5.1 and can boot normally when I insert a video card temporarily.
When I remove the card and restart, it won't boot completely.

Is there a way to change boot options or edit grub.cfg to ignore graphics check?

Thanks!

Hi,
I assume it's has nothing to do with proxmox - I have two servers without video card (rs232 only), which boot perfectly.

I guess that an bios setting prevents an headless boot?

Hi again,
you can set an serial console in /etc/default/grub:
Code: 
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8"
GRUB_TERMINAL="serial console"
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=1 --word=8 --parity=no --stop=1"
after update-grub perhaps it's work? But, like I wrote before, I guess an bios setting is the boot-blocker.
