This is from a Natty CD that had its MD5 checked as accurate, and checked as accurate by the live checker when you boot into it.
During the opening of the live CD, when I pressed a key to go into the more "verbose" mode instead of the Ubuntu logo with the progress dots, it just stopped after a little while, and never booted.
I then proceeded to boot from the live CD without going into the more verbose mode, and it worked fine. I installed it, and it booted successfully. I then installed all the updates from the update manager and Nvidia driver from the "Additional Drivers" tool. I restarted to apply the updates, and then during boot, it just stopped after "Checking Battery State" or a similar battery check. On trying again, it stopped after saying something about a bad USB check or something. I then proceeded to try to install it again twice. The first time it crashed during install and said the CD was scratched, or the drive was bad. The next time it crashed without giving me a useful error. The live CD runs fine, but install is really being a pain. Also, during the install, during the slideshow, it keeps saying "Ubuntu 10.10" when this is 11.04.
Attatched is the "LSHW" hardware info for my machine.
I downloaded this ISO- http://cdimage.ubuntu.com/daily-live/current/natty-desktop-i386.iso
