I have just installed Ubuntu 14.04 LTS on my laptop with Windows 8 installed. Now I can boot into Ubuntu without any problems, but I can't boot into Windows 8. After I choose Windows 8 Loader (on sda1), It direct me to the same grub screen.

I have tried boot-repair using recommended repair option and this is the result.

"Boot successfully repaired Please write on a paper the following URL: http://paste.ubuntu.com/8544452/

... Please repair the bootsector of the sda1 partition ... this can be perforn such as TestDisk "


For some reason grub has damaged your Windows boot record.

To install and run testdisk open terminal and enter sudo apt-get install -y testdisk && sudo testdisk

For help using testdisk look here. And for additional information check out the forum post here.

You will probably need to run boot-repair one more time after the damaged Windows boot partition has been fixed with testdisk.
