I had already windows 7 in my laptop. I installed ubuntu16 using "Install ubuntu alongside windows 7" option. Ubuntu successfully installed but when I restart my laptop , the ubuntu boot menu appears and it shows option-
- Boot from ubuntu
- Boot from windows 7 OS.
If I select 1st option I can successfully enter in ubuntu. But if I select 2nd option to boot in windows , Suddenly,a purple screen appears and laptop hangs. then I have to forcely restart my laptop.
What is the solution of this problem,How can I boot from windows?
