Folks -
First off, thanks for taking the time to help out. It's appreciated, and I'll do my best to give back on that helping just as soon as I get past this hiccup. :)
I've installed Ubuntu 12.04.1 Desktop AMD 64 on a new set of hardware - new HDD, motherboard, RAM, etc. Upon restarting after the clean install, I'm seeing the following glaring message: "Read Error". No detailed error codes, nothing giving specifics, just Read Error.
Thinking this was something wrong with either a) the install disk or b) the disk drive itself, I made a new install disk and verified the image again, then reinstalled. No change. Then I booted into the Live CD and check the S.M.A.R.T. data and ran an the self-assessment check; everything on the disk checked out. No luck there, so I turned to research.
I did a slew of Googling and found most of those issues starting with this message turned out to be GRUB issues. After a whole lot of poking at things beyond my knowledge (reinstalling & upgrading grub, among others), I went ahead and ran the bootinfoscript (http://bootinfoscript.sourceforge.net/) and got the following output:

Unfortunately, I'm way out of my league, and maybe even going down the wrong path to begin with, so I'm hoping someone can take a look at this output and suggest next steps.
Thanks again for all the assistence,
Jen
