12.04 won't boot from Live CD or USB

My laptop (the only PC left in my home to install Ubuntu 12.04 now that it's out) is not booting from Live CD or USB. I get past the screen with the little person in the circle. but right after that, just black screen with the white cursor or indicator at top left. It just keeps blinking for hours.

What should I do?

The CD is the same that I used for the other PCs; they took it fine. I made the Live USB in Ubuntu 12.04 using the startup disk creator and the Live CD with the Windows 7 iso burning software that is preinstalled.

Here are my computer's specs: core 2 duo, 4gb ram, 320gb hdd, nvidia gt 120m, 720p monitor, dvd-rom.

If you can't boot without acpi = off and nolapic, that means that the ACPI on your computer is not supported by Ubuntu.

A bonus if 10.04 worked! Before Ubuntu 10.04 it had the driver to support the ACPI. They removed the driver from 10.10 and beyond.

Since you said that there are no other operating systems, you can disable the new card (BIOS) or disable ACPI (also from the BIOS). Use the second option if you can't find the New Card Interface.

Don't try this on a Windows computer, though. This might wreck Windows but it won't do any harm to Ubuntu.

Good Luck!

Edit: By the way, you don't have to reinstall Ubuntu after disabling the ACPI (If you didn't remove it.)
