I have a dual boot machine with Windows 8.1 and Ubuntu. Yesterday I tried to reinstall Ubuntu to use a lot of the free space I had in my hard drive. I wasn't very smart and I simply formated my old Ubuntu and grub partitions (which only had something like 15 GB) and joined all the free space into a 350 GB partition. I created a USB drive with the recovery image for my Windows 8.1 and proceeded to try to reinstall Ubuntu.
That's when everything went down the drain. Before reinstalling Ubuntu, I've tried running the Windows 8.1 recovery tools. When I tried to refresh my system, it required me to insert the recovery media, which I didn't understand, as I was already running it from my recovery media.
I got desperate and copied all the files from the Recovery USB drive into another machine and created a new Ubuntu live USB. I reinstalled Ubuntu into my free space, but now Windows is not recognized anymore. Grub shows up, but there's no Windows option. There is some Windows Recovery Option, but all it does is go back to grub. Ubuntu finds the Windows partition, and I can actually access all my files from it. But I cannot boot Windows from that partition. I still have a recovery tools partition that came with my laptop too, but I'm not being able to boot it or run it.
I know I did lots of stupid I stuff. I didn't backup my Windows partition, I have overwritten my recovery USB drive with my Ubuntu image. But now the deed is done. I will be more careful. But, as I can access all my Windows files from Ubuntu, I think there's still some hope to recover Windows.
Thanks in advance.
