Ubuntu Installation :: Dual Boot Upgrade Hangs On Install Restart At Starting Up

I've been using ubuntu for a couple of years rather successfully on my dual-boot Vista/Ubuntu. It upgraded to 8.0(4?) LTS, 10.04LTS and I kept it there until this afternoon I followed the instructions on the ubuntu site to open up a terminal and update-manager --somearg to provide me with a nice little "Upgrade" button on the update manager. I clicked said button per the instructions, let it do it's downloading and whatever else it does. The last step of the installation is a system reboot. I let it do that, and then my grub menu comes up as more-or-less this:

Code:
Ubuntu 10.04 LTS, kernel 2.6.32-32-generic
Ubuntu 10.04 LTS, kernel 2.6.32-32-generic (recovery mode)
Ubuntu 10.04 LTS, kernel 2.6.24-28-generic
Ubuntu 10.04 LTS, kernel 2.6.24-28-generic (recovery mode)
Ubuntu 10.04 LTS, kernel 2.6.22-14-generic
Ubuntu 10.04 LTS, kernel 2.6.22-14-generic (recovery mode)
Ubuntu 10.04 LTS, memtest86+
Other operating systems:
Windows Vista/Longhorn (loader)

If I select the top one, I get:
Code:
Starting up ...
with a blinking cursor under the S for a LONG time (used the power switch after ~40 mins). I tried the second 2.6.32-32 option for recovery mode. It spit a bunch of gibberish to the screen for a couple seconds and then stopped, presumably doing the same thing, just with 100% more gibberish. I tried booting into Vista, that worked fine. Just to reiterate, I've not yet seen a 10 LTS login screen or desktop, and can't get one yet (just a "Starting up ...") Just to add, I did try searching, but since the only info I had to go on was 8 LTS to 10 LTS upgrade, and "Starting up ...", well those are just hard keywords to get any meaningful info.
