I've tried to install Ubuntu on my VAIO T13 (Ivy Bridge) Windows 7 laptop using windows installer but it doesn't work. After the system restarts, it said that I don't have the root folder and advised me to change in the partition (which I don't understand)
What should I do next?
P.S.
1) I've read this solution but I don't understand http://ubuntuforums.org/showthread.php?t=2127699
2) I'm very new to Linux, so may I have a bit detailed process please
Thank You
