I am a student and recently stuck on a problem. I was successfully using dual boot (windows 8.1 and Fedora21 Linux) on my pc and last night I was trying to re-install windows 8.1 . While installation I was facing some issues and I accidently run these commands bootrec /fixMBR, bootrec /Fixboot , bootrec /rebuildBCD through command prompt in trouble shoot option. Later after restart , It didn't ask for boot option to select the operating system and now It directly boots to windows and doesn't ask/show the operating system list to load. I hope fedora is still in there and my notes are too. I tried searching out the internet but couldn't find the way to make it . Can I get the dual boot list again ?
