sr0 is your CD/DVD drive btw. This could mean defective hardware (CD/DVD) or even worse.

Sounds like hardware issue to me. Is your CD?DVD running OK or is the disc in good state?

If it didn't ask for partition during install (and you're sure you didn't miss it), then I think you didn't install Ubuntu at all or installed it improprely or is this livecd?

That boot selection window is called Grub. It gets you to busybox shell which means it probably doesn't find initramfs image or can't mount some stuffs (initramfs contains boot-time info that is vital)

Try these :
 - Google first with the partial errors ('end request, I/O error, device ....' as the search query)
 - try removing some kernel parameters from your Grub (remove 'splash' and all those crap. leave only 'quiet' there if there is such option. if not, just chuck it in)  and watch those error messages. the reasoning is to get to see what is making those error messages pump out and drops you to busybox shell. ;)
 - I am guessing you aren't mouting properly and so can't mount the ramfs. 

Ping back if you can't get it working. also there are some people on #ubuntu-np at irc.freenode.net if you need help. I myself am quiete busy so I can't be of much help except this list from time to time. 

cheers
