I have installed Ubuntu with windows 8 and now I am getting errors as:

Invalid EFI File..

Please help me solving this problem. I tried to repair using boot repair but am getting an error there as well. This is the report generated using boot repair.

It looks like you had Windows installed in BIOS/MBR mode, but installed Ubuntu in UEFI/gpt mode. That converted MBR drive to gpt. And Windows only boots from gpt drives in UEFI mode. Did you manually install Windows in BIOS mode on a UEFI system? –  oldfred Apr 14 '14 at 15:32
