I tried to install Ubuntu 11.10 on my DELL Studio XPS running with Windows 7 Professional. Following the recommended installation steps found on the internet, I first downloaded the ISO file, burned it on CD and restarted the system from this burned CD forced by pressing F12.
Nothing happened (black screen with blinking cursor) and after a while normal Windows 7 startup appeared. Finally I tried the 32bit as well as 64bit version with the same disappointing result.
What am I missing?
