Ubuntu is my primary operating system, and I DO NOT HAVE WINDOWS INSTALLED ANYMORE. When i try to install ubuntu 12.4 or 11.10, somewheare at 90% of the installation completed it either crashes, either it switches to the terminal (fullscreen if you know what i mean), or it will freeze. This has been ongoing for a while. i've tried different disks to install ubuntu, the flash drive, and even the low quallity graphics installer. i've tried many of they'se things, but none worked. my computer is Asus p5ql pro, ati radeon HD 3850, and intel dual core 3gh. PLEASE HELP!!! i dont want windows anymore, i just need linux.

Maybe first you have to hit ESC at the welcome screen(see picture attached), then select your language, then you get the "Try Ubuntu.." screen previously mentioned by Web-E..

On an ASUS? Try this:

Go to BIOS > Security> I / O interface Security> "New interface card". Set it to Locked.
