On my system I can disable secure boot, and I can use legacy/bios however with legacy/bios when I install ubuntu 13.10 or fedora 20 my windows 8 boot sector is literally destroyed and I cannot boot windows 8.

When I install ubuntu with secure boot enabled or disabled I cannot boot ubuntu either with usb or dvd. I get error message stating that the kernel must be loaded first.

Am I missing something I thought that linux (fedora and ubuntu) could be installed with efi.
