I had a system with 64-bit Windows 7 Home Premium installed and I installed first Fedora 64-bit alongside it. Then I decided I can do triple boot and installed Ubuntu 14.04.1 LTS 64-bit using manual partitioning without altering anything about Windows partitions. I tried to boot Windows 7, but it did not work; however, Ubuntu works fine. How can I restore Windows 7?
I've used Boot-repair to fix Windows-Linux: https://help.ubuntu.com/community/Boot-Repair
If you can't run from Ubuntu it's easy to make bootable disk, run the repair program on it.
