Grub error 18 means that your hard drive is larger than the BIOS can address. Linux only uses the BIOS to address the hard drive during boot so boot is the only time the problem can appear.

The way to solve the problem is to create a small partition -- maybe 300 megs or so -- at the beginning of the hard drive and place /boot in that partition

In addition to your other partitions, just create a ~200 MB ext3 partition at the beginning of your HDD like pennacook mentioned, and then when you go through the Ubuntu installation process, set the mount point on that partition as "/boot". If you need more specifics, how about first opening a terminal (Applications > Accessories > Terminal) and post the output of:

sudo fdisk -lu
And we can work from there if you want.
