The last time I needed to install Ubuntu on a system without a CD drive, my Eee PC, I created a bootable USB drive to run the graphical installer. The UNetbootin tool I used makes creating the USB system simple, but in Ubuntu 8.10 there’s an even easier way.
You’ll need:

• The USB Startup Disk creator tool. It comes as a part of the default Ubuntu 8.10 desktop. I haven’t seen any packages for older versions of Ubuntu yet, but I have have been able to install the 8.10 package in Ubuntu 8.04.
• A USB drive or memory card with a minimum of 700 MB of free space.
• An Ubuntu CD or Ubuntu CD ISO file.

Launch the USB Startup Disk creator tool from System->Administration->Create a USB startup disk.
