I had a problem with install Ubuntu 13.04 next to Windows 8. I have a Dell inspiron 15 notebook with UEFI.

In Boot-setup I changed to Legacy Boot on and switched UEFI boot off. Then I installed Ubuntu but the computer always starts Windows.

I have followed the instructions here : UEFI but it hasn't helped.

I used Boot-Repair and it helped; but It did not list Windows 8 in grub. Then I wrote with QGRUBEditor Windows 8.

Now when I turn on my notebook in grub I have Windows 8 listed but if I choose it I get the error

Invalid EFI file path. 

What can I do to fix this?

I believe that if Windows 8 was installed in EFI mode then you change it to not EFI you have to reinstall Windows. This question may help Installing Ubuntu on a Pre-Installed UEFI Supported Windows 8 system –  Warren Hill May 18 '13 at 12:22
    
Any answer is a guess at this point. Please post either the URL that Boot Repair provided or a pointer to the RESULTS.txt file that Boot Info Script generates. That will provide the information needed to provide advice without guessing. –  Rod Smith May 18 '13 at 14:37

My "error invalid EFI file path" error was solved by install an alternative boot manager:

http://ncu.dl.sourceforge.net/project/refind/0.7.5/refind_0.7.5-1_amd64.deb

PS: My setup: 12.04.3 LTS amd64-desktop with BIOS set to "UEFI" mode.
