How to fix? (can't find gfx mode in grub)

Hi!

I updated grub.

When I boot my pc, after grub-menu a error message appears with
can't find gfx mode.

All is set correctly.

How to fix that?
Please help, thanks!

Got it,
recovered my older 00_header file in: "/etc/grub.d"

Now, the error-message is gone.
