Re: Cannot install Ubuntu 10.04 from demo
It's not a "demo version"; it's a LiveCD. The version on disk is the "full version", not a demo.
You should NEVER force an install on an untried machine -- bad idea.
Boot from the LiveCD and try it out first. Anything that doesn't work will range from trivial to impossible to fix after installation.
Post back here with any problems you encounter using the LiveCD.
Mint 15 & 16; MS Win7 & Win8.1.
Will not respond to PM requests for support -- use the forums.
