I have a laptop that supports EFI/UEFI. I have Windows 8.1 and Ubuntu 12.04 on it. The way I installed my OSes was like this:
I installed Win 8.1 in the required partitions then Installed ubuntu and installed the boot loader in the same partition that I installed ubuntu. The previous time I did so, I used boot-repair to fix my grub so it would show both windows and ubuntu OSes and it worked. That way Windows were intact and in the case that ubuntu screw up (upgrades) or I screw up (messing with it) I wouldn't have to install Windows all over again. This time tho, boot-repair showed me a message like the following one:
WinEFI or WinUEFI (I'm not sure which one) detected, do you want to backup and rename the files
And like a noob that I am, I clicked yes. Now grub replaced both boot loaders, and no matter which efi entry I select from bios, I get the same grub screen. That didn't happen before, If I had ubuntu efi as primary boot entry I was getting grub and was able to select linux or windows. If I had win 8 boot entry as the primary one. I was getting pure windows.
And FINALLY (I know) the question... boot-repair said that it backed up WinEFI loader or whatever. Does anyone know how I can restore it?
Thanks in advance.
