This question already has an answer here:

I have installed Ubuntu using Wubi on my Windows 7 machine (Sony Vaio). Everything installed perfectly, but whenever I reboot my system there is no Ubuntu (there is no dual boot menu). I checked my Windows setting and it seems there is only Windows (it could not recognize Ubuntu).

Could anyone help me how to solve this problem.

This question was marked as an exact duplicate of an existing question.

Please remove Wubi completly from Control-Panel (Add/remove softwares). Wubi sometimes can cause some problems, and installing with a Disk or a DOK (Disk On Key) is better. (And you have to remove Wubi for installing normally)

Download the ISO file and make a disk or a DOK. there are guides in the Ubuntu sites for creating both.

If you need to ask something, ask (:
