Until yesterday I had a dual-boot of Windows 8.1 with linux Mint 17.2 Rafaella Cinnamon 64bit.
Via the terminal I deleted something that I shouldn't and then when I rebooted the PC, linux stuck at the Mint logo. So I decided to delete the linux. In Windows I deleted the linux partition restarted the PC and a GNU prompt would appear and I couldn't load windows.As a solution i found two ways to delete gnu and be able to load windows normally.
The first one included using the Windows installation disk go to repair open CMD and type /bootrec.exe fixmbr, /bootrec.exe /fixboot (tried it several times with different order) didn't work (GNU was still there). Then I found this How to boot windows after uninstalling ubuntu?, which apparently removed GNU, since the PC boots Windows. After that Windows work fine. Now when I boot linux from live DVD, the screen says could not open "\EFI\BOOT\fallback.efi" :14. Also when I want to install linux alongside windows, it doesn't recognise that the HDD has another OS. I really need to install linux again so what can i do? If I select something else for install will it affect windows 8.1?
