I wanted to have a feel of ubuntu so I installed Ubuntu 14.04 LTS on windows 7 using a USB stick to boot. But I made a horrifying mistake of not installing ubuntu on a separate partiton. This resulted in removing my windows 7 completely from my laptop along with the previous partitions. Now all I have are two linux filesystem partions : one swap and one for every thing else.
I have my factory default image of windows 7 burnt to a DVD. When I try to restore this image using the factory reset DVD of windows 7 I get an error saying that :
"The program cannot restore the system partition because its structure is incorrect. You may have to recreate the partition to continue."
Please help me restore my windows 7 back and reinstall Ubuntu alongside windows.
