Netbooks don’t come with a CD, I installed the distro from a Flash Drive, you have to go into the BIOS and change the boot order so that it will boot from the flash drive, but it’s pretty straightforward.
In case the original poster reads this, you can probably temporarily set your “boot from” directive by depressing either F2, esc, or F12. This avoids entering the full fledged BIOS program (it should create a list of “boot from” options instead), which sometimes puts people off from going futher with Linux.
