I just recently installed Ubuntu 9.04 on my laptop with no problems whatsoever. I'm just now learning that 9.04 is unsupported and it's making installing software difficult. I came to the conclusion that I should just update to the latest version. I then found the latest version at the time 12.10 and made my disc so I can repeat the installation process I did for 9.04. Which brings me to my problem, I can't install 12.10 because I come across certain problems.
I have made the proper changes to my BIOS to make first boot option my CD/DVD ROM and then I get to the Ubuntu Menu:
Try Ubuntu without installing option takes me to a black screen with a blinking cursor on the top left of the screen and stays there.
Install Ubuntu option takes me to a black screen with a blinking cursor on the top left of the screen and stays there.
Check disc for defects option takes me to a black screen with a blinking cursor on the top left of the screen and stays there.
Test Memory option takes me to a blue Memtest86+ v4.20 which fails at 47% on Test #7 [Random number sequence] and leaves me no choice but to hit (ESC) to Reboot. Now assuming this was my issue then the next option wouldn't work, correct?
Boot from first hard disk option takes me to Ubuntu 9.04 and runs just fine.
Things I've seen while researching my problem is a bad iso file. I can assure you that I already validated my "ubuntu-12.10-desktop-i386.iso" file with winMd5Sum. I'm thinking it has to do with the GRUB. I have no idea what that is or how it effects my boot process.
I apologize for such a lengthy description of my problem but I hope it has given enough information so that when it is answered it helps anyone else with similar type of issues.
Below I have given screenshots of my computer. I left out the black screen with a blinking cursor because it's literally what I explained it to be.
