So, I had bought a new laptop which came preinstalled with Ubuntu 14.04 but I later installed Windows 10 after removing Ubuntu, I backed up laptop vendor's Ubuntu image though which came on the laptop.
Later, I decided to have a dual boot configuration so I installed Ubuntu using the same vendor image I had backed up. Ubuntu installed succesfully but now I am unable to boot into Windows as it is not showing up as an entry in grub.
I tried boot-repair but it doesn't seem to work. Although I got the url http://paste.ubuntu.com/14429794/ It keeps repeating the message to 'unmount partitions' even in a live-usb system. I then tried bootscriptinfo which gave the output given below.
Also, I am sure that the whole windows partition is intact as I can see all the files in Ubuntu, it's just that I can't boot from it.
EDIT: I also tried the setroot method in the grub command line but it gave an error saying that the EFI path is not valid.
Any help would be greatly appreciated as I have already spent much time scouring forums and searching on Google.
