I have a HP pavilion zd8000 machine 80G HDD, 1G RAM, Pentium 4. I can get Ubuntu to run on it in the "try" mode, but it will not install. before it gets to the screen where you choose to run alongside windows, I get a screen full of messages and it just stops. Could the CD I created be corrupt or is there an incompatibility issue with the PC?
Have you reviewed this bug report:
Initially I thought, compatibility issues with your laptop are unlikely since others have had good success getting it to run on a HP Pavilion ZD8000.
though not relevant, here are the instructions for md5sum checking:
You can follow the instructions at https://help.ubuntu.com/community/HowToMD5SUM to check whether your CD is corrupt. If you have a linux system running, you can use the commandline
(Details at the link above)
On windows you will have to download a program to calculated the md5sum of a disk such as winMD5Sum.
I tried installing 12.04.2 to a HP zv5000 (laptop) from DVD (when given the 2 buttons 'Try Ubuntu' or 'Install Ubuntu' - I selected the Install option) and encountered, and got stuck on, the similar text msg page.
I restarted PC, loading Ubuntu in the 'Try Mode' (from DVD). Then I click on the 'Install Ubuntu 12.04.2 LTS' icon on the Ubuntu desktop and I was able to proceed.
Hope this works for you too.
