Trouble with the Graphical GRUB Screen on an x86-based System?

If you are experiencing problems with GRUB, you may need to disable the
graphical boot screen. To do this, become the root user and edit the
/boot/grub/grub.conf file. Within the grub.conf file, comment out the line
which begins with splashimage by inserting the # character at the beginning of
the line. Press Enter to exit the editing mode. Once the boot loader screen has
returned, type b to boot the system.

Once you reboot, the grub.conf file is reread and any changes you have made
take effect. You may re-enable the graphical boot screen by uncommenting (or

adding) the above line back into the grub.conf file.

Problems with Booting into the Graphical Installation

There are some video cards that have trouble booting into the graphical installation program. If the installation program does not run using its default settings, it tries to run in a lower resolution mode. If that still fails, the installation program attempts to run in text mode. One possible solution is to try using the resolution= boot option. This option may be most helpful for laptop users. Another solution to try is the driver= option to specify the driver that should be loaded for your video card. If this works, it should be reported as a bug as the installer has failed to autodetect your videocard. Note To disable frame buffer support and allow the installation program to run in text mode, try using the nofb boot option. This command may be necessary for accessibility with some screen reading hardware.
