GRUB breakdown

[Daniel Mons]

Ubuntu (actually Debian, but it's in Ubuntu too) has built in automated 
management scripts to generate your GRUB menu.lst without needing to get 
your hands dirty.

If you can boot cleanly into Ubuntu, fire up a terminal and type

sudo update-grub

The scripts will scan your partitions and boot sectors, and add any 
found Linux kernels as well as Windows (and other) operating system 
chain loaders automatically to your menu.lst.  From there, merely reboot 
and you should see the new entries appear.

There are dozens of other update-* scripts used for system management of 
default programs, rc/init.d script management, python management, font 
cache management, etc, etc.  Using these over manual hacks is highly 
recommended, as they do it "the Debian/Ubuntu way", and the changes 
often stick around even after you dist-upgrade in the future (which 
causes far less breakages when upgrading to new releases down the track).
