Error on boot: unknown command 'gfxmode'. Pressing any key continues
A few days ago, I installed Ubuntu 12.04. I changed the order of systems on the list of boot loader (I use Windows Vista and Ubuntu on one computer). I also changed, by the way, the appearance of the selection screen (resolution). All this with the Grub Customizer. After reboot and after the list of systems to choose was shown, I got a message: „Error: unknown command 'gfxmode'. Pressing any key continues ... ". Ubuntu starts even without pressing any key. The problem is repeated each time when I run Ubuntu. How to solve it?
