I have a dell inspiron laptop, with windows 8 pre-installed. I upgraded it to windows 8.1 preview.
A few days later i tried to install ubuntu 13.04 (via usb), it got installed (separate partition created via windows). But would not load, instead windows loaded. So after a bit of googling i ran boot repair, and then both my OS's were gone. No option to boot any OS.
So I installed ubuntu via usb again. It is working fine now. But I want to know how bad have i screwed my Windows, would i be able to get it back running, if not would i be loosing my other files as well?
