Ubuntu freezes

Hey all.

I really need need some help so here's my problem:

I installed ubuntu 6.10 on an older laptop with no working operating system. The install went fine, finalized okay, etc., but when I removed the installation disk after install and tried to reboot, ubuntu froze up. It takes me past the first black ubuntu splash screen with progress bar to a peach colored screen where the mouse cursor animates briefly then the whole process stops. it just sits at this screen. Please help, I have to get this laptop working. thanx!!
