I've bought a dell inspiron 660 preinstalled with windows 8. When I install Ubuntu 12.10 and use boot repair I am able to boot into ubuntu but not windows (invalid efi file path) I have tried reinstalling on numerous occasions but still get the same response. I assume I am doing something really simple wrong and would appreciate any help. Here is the last output from boot repair : Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/shimx64.efi file!

What version of 12.10 did you install? 32 or 64-bit? – horIzoN Mar 5 '13 at 16:20
64 bit ubuntu boots in secure mode perfectly but windows just goes to efi file path crap – peterden Mar 6 '13 at 10:46
