I am trying to install Ubuntu on my PC but it doesn't show the boot window.
When I started my PC and went in the disc clicked on Wubi, it showed demo and full installation.
I clicked on that.
Then, there were 3 options. I clicked on help boot from CD but it started installing something and then showed an error:
COULD NOT RETRIEVE THE INSTALLATION FILES so I cancelled that.
What should I do?
How do I install Ubuntu on my Windows 7 PC?
