This question already has an answer here:
I've tried almost all the tutorials. I've researched for a very long time (probably missed something). I would really appreciate some help. I have a Toshiba Satellite with Windows 8 pre-installed. I installed Ubuntu 12.04 and used unetbootin to burn it to my USB. I disabled "Secure Boot" from the UEFI. I changed the settings in the UEFI to make the USB boot first. I'll get to the screen where it gives me the option to: 1. Try Ubuntu without installing. 2. Intall Ubuntu. 3. Check the disc for errors. If I select either option 1 or 2, I get a blank screen and my computer just sits there and runs. Nothing happens. I have a feeling this has something to do with either the graphics card on the computer or the UEFI screwing me over. I don't think it will allow me to do "nomodeset" or anything like that. I've checked the md5 sum and it's correct. What should I do?
