I was doing fine with 12.10 but I read that 13.04 took care of a few of the more sluggish aspects of 12.10 so I decided to upgrade.

The installation package seemed significantly less smooth than 12.10- instead of a snappy, smooth experience it had a few graphical bugs and took a LONG time to load, with various pools of unresponsiveness. Regardless, I went through with it.

Now, unless I boot from USB from the BIOS menu, the computer simply does not boot Ubuntu. I re-installed, to no effect. There is just a single flickering | on the top-left. Randomly pressing keys, after the first 7 or so, starts producing system beeps. The system is not completely unresponsive: It turns the screen on-and-off if I press "Ctrl+Alt+Del".

Pressing shift makes no difference.

Are you getting to the grub boot selection screen? Or does it get stuck before then? If it gets stuck before loading grub you probably need to reinstall grub.

No boot selection screen at all. Literally the most powerless computer interface I've ever handled in my life. It's a blinking carat that beeps or reacts to CAD. I re-downloaded the image on a windows computer and used a different program to burn it to USB. It feels slightly better this time around, but it could be all placebo. Please do tell me how to reinstall grub in case I reach another dead-end. –  user153011 Apr 27 '13 at 21:53
    
Ok, its a bit tricky but if you read it carefully it should work just fine. Hopefully grub is the only thing that has messed up : ) Here is an article that explains how to: opensource-sidh.blogspot.co.nz/2011/06/… –  Anonymous Apr 28 '13 at 3:31

There is a bug with the kernel that effects nvidia drivers
You can either upgrade to saucy or use a mainline kernel

I would use a live cd to edit my /boot/grub/grub.cfg file and change every timeout=0 to timeout=10 This way I will have a chance to push keys during boot
This command should get the job done:
sudo sed -i 's/timeout=0/timeout=10/' /media/$USER/*/boot/grub/grub.cfg
you will need to mount the partition with /boot on it.
