GRUB Error Messages
Grub Error 18
on restart after installation.
On older machines with an older BIOS and fitted with a large hard
drive, there may be a problem if Ubuntu is installed onto a partition
not within the first 1023 cylinders of the hard drive. The
solution is to alter the way the drive is partitioned so that the boot
directory is at or near the beginning of the drive. Rather
than
install the whole system low down, you can make a separate partition
for the boot directory. In the partitioning phase of setting
up
the installation, make a small partition near the beginning of the
drive and assign it to /boot.
A larger partition assigned to / may be put
anywhere on the drive.

Gutsy Specific Problems
-
Missing bootup display
When
Gutsy was installed on a laptop with a screen resolution of 1024 x 768
the screen went blank between the boot menu and login screen.
The
problem was that Gutsy is configured to use a screen resolution of
1280x1024 and any screen not capable of this resolution will be
blank. The cure is to edit a conf file to 1024x768 instead.
(Or
whatever the max screen res is)
Open Terminal and enter :-
gksudo
gedit /etc/usplash.conf
The text editor will open and show the following :-
# Usplash configuration
file
xres=1280
yres=1024
This wants editing to :-
# Usplash configuration
file
xres=1024
yres=768
Change the values, Save
and Exit.
However, we're not quite done yet. Use the following :-
sudo
update-usplash-theme usplash-theme-ubuntu
That
fixed it for me. Reboot and you should see the usual orange
loading screen. (If your max screen res is less than 1024x768
then use the appropriate values.)
