After update to SUSE Linux 11 SP4, it stuck on a black screen written grub>

After updating a Suse Linux 11 to SP4, I’ve booted the server and it was stuck on a black screen written grub>

To solve this problem it is needed to:
Boot using a Suse Linux 11 DVD
Select Rescue System
Choose a language
Login as root

# grub
find /boot/grub/stage1
root (hd0,0) -> type according to your system, found using find /boot/grub/stage1
setup (hd0)
quit

Reboot the server
reboot -d -n -f

Remove the graphical screen with progress bar in Red Hat Enterprise Linux and Suse

Edit file /boot/grub/grub.conf or /boot/grub/menu.lst and on the line that contains the word kernel, remove the word splash or rhgb (Red Hat Graphical Boot) from this line.

You will boot in text mode until it is time to transition to graphical mode otherwise you will remain on text mode.

Use this to check all console messages when booting. Useful if you need to connect remotely and pressing Esc or F2 fails

root@suse9:~ # cat /boot/grub/menu.lst

If you need to check, boot the kernel using the option splash=off or remove rhgb. You also can use consoleblank=0 to not turn off the screen.
