I downloaded the
ubuntu-12.10-desktop-amd64.iso, then I created a bootable USB stick using the guide from here. I booted via the USB stick, then after the Ubuntu logo and some circles loaded beneath it, nothing happened and my laptop started making some weird noise.
So I booted the USB again, but this time with
nolapic enabled. This time the booting process went past the circle loading thing, but halted, and the weird noise started again.

Why isn't the OS booting properly?
