When I try to install Ubuntu 12.04 64-Bits on my desktop computer, I don't get any video output from the installation since I click "Install Ubuntu" (or something like that). It stays with a black screen just like in a console.
I googled about my problem and I found that maybe Ubuntu isn't capable of showing image when running on a Nvidia Geforce GTX 550 TI, but I couldn't find any solution. How can I install Ubuntu on my dear computer? :P
PS: The problem isn't with the USB I use, I installed already Ubuntu 12.04 64 into my netbook Asus 1215P, and is working fine.
