I have a HP Pavillion g6-1330se laptop with Intel i5 processor, 6GB RAM, Radeon Generic PnP display and Windows 7 Home basic version. I have downloaded Ubuntu Desktop 12.04 LTS from the website and have extracted the .iso file on to an external DVD. However, upon trying to boot from DVD, I get a blank screen. Also, I tried installing Ubuntu using Windows installer - while the installation goes through successfully and during booting I get options to select Windows 7 or Ubuntu, upon selecting Ubuntu, I get a blank screen.... How can I resolve this problem? Thanks in advance.
I have the same problem with ATi Radeon 6750HD. When you get the option to boot into Ubuntu, press Enter and quickly hold left Shift key. Choose Ubuntu recovery mode. It will give you a set of options. Select Resume normal boot and you are good to go.
