Hello All:

I just installed Ubuntu 11.10 on my new 64 bit barebones AMD Diablotec Kit from Tiger Direct. The installation is smooth and the graphics are excellent while installing and updating. After I remove the CD and reboot, the trouble starts.

After the Bios confirms everything works, I get a purple GNU Grub version 1.99-12ubuntu5 screen with the options to load Ubuntu, with Linux 3.0.0-12-generic, the same thing in recovery mode, and then two selections for the memory test. There is also a floating box saying "Input Not Support" for my AOC Monitor.

I looked at similar threads and could not find answer to my problems. None of the boot options work. Booting into generic causes a black screen and freeze. Booting into recovery mode gives me a purple screen with distorted tears on the top and left side of the screen. The mem tests work, but freeze midway and are followed by the Cap and Scroll Locks flashing on my keyboard.

I also use Linux Puppy and thought maybe I could use it to boot and modify the graphic setting for the Ubuntu start up. My graphics card is an onboard GeForce 7025/nForce 630a chipset and my processor is an AMD Athlon II AM 3 64-bit processor with 8 GB DDR 3 Ram. Unfortunately, I've only used linux off and on and have no idea where to start. Any help would be greatly appreciated.

When installing, the system is highly responsive and smooth and moves fast, so the potential is there for a rocking Ubuntu system. I just don't know why the installation screen resolution is perfect (1366 x 768 16:9) on my monitor while the hard drive boot has graphic issues and a different resolution. I cannot access the console or anything.

Thank you again for any help you can provide.

In order to troubleshoot any Ubuntu install problem you should first check the md5sum of the Ubuntu iso image that you downloaded, as well as the md5sum of the Ubuntu install CD that you have made. This will rule out a corrupted installation media as the source of your troubles.
To check the md5sum of the iso image that you downloaded, see this: https://help.ubuntu.com/community/HowToMD5SUM
And to check the md5sum of the install CD when it boots: https://help.ubuntu.com/community/BootOptions

If the md5sums do not check, then you need to download a new iso image of Ubuntu and / or burn a new CD at the slowest possible speed in order to minimize the chances for a corrupted CD.
If the downloaded Ubutnu image and the install CD check out OK, then when you boot the Ubuntu install CD open a terminal and post the output of: This will give us a verbose (-v) output of your hardware (lspci) as well as what drivers are loaded (-k) for your hardware.
This info may help to troubleshoot your problem.

And welcome to the LQ forums!!!

Thank you for the assist tommcd. I did not think about the md5sum, and that was one problem. I burned a new disk at the slowests speed and was able to create a valid copy.

After reinstall, I did get farther, able to access the Ubuntu shell, but the computer seemed to take forever to reboot and the shell itself had issues. I made it to the console and attempted to make changes (because I just built my pc and really wanted to dig into it), using advice from others with similar problems.

Unfortunately, I took one step ahead and then 3 steps back. Eventually I couldn't boot the computer and decided to install Ubuntu 10.10, which worked flawlessly.

Every cloud has its silver lining and I learned a lot from this experience. I did a lot of studying trying to fix my problem and have decided to go Linux only. There is one windows xp computer, which my little ones use, and everything else is either Ubuntu or Puppy.

Thanks again for all the help everybody provided.
