This question already has an answer here:
I have a windows 8 laptop, 64 bit OS, x64 based processor. I downloaded Ubuntu 12.04 LTS matching all of these specs. I go to boot it, and I hit "install Ubuntu" but it just gives me a blank screen. I let it sit for 10 minutes, but it didn't change, so I tried it again. Same result. I tried running Ubuntu without installing and it still didn't work. Any suggestions?? And am I supposed to run wubi.exe file??
