    Clean Install - Read Error on Startup

    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,

    Did you burn the CD at low speed?

    I would try installing with the alternate install CD.

    Both times the disk was burned at maximum speed, then verified. To satisfy the above suggestion, I got the alternate mirror and burned at the lowest supported speed of my burner, then verified again. At the end of the install, upon reboot (without the disk, mind you), I got the same "Read Error" message.

    Any other thoughts now that we've got basic disk failure and image corruption pretty thoroughly ruled out?

    Been doing some reading here and this seems to have a possible fix.
