This question was marked as an exact duplicate of an existing question.

So what happened when you picked the win8 option from the grub menu – damien Sep 16 '13 at 0:26

Have you tried booting into windows without using grub? If you have an option to access UEFI have you tried booting from there? Try booting the recovery partition. I don't know why, but in the past the one that said recovery was actually my primary os. If that one doesn't work, try each of the listed efi's one at a time using the entry that looks like this:

menuentry "Windows UEFI bkpbootmgfw.efi" {
set root='(hd1,gpt1)'
chainloader /EFI/microsoft/BOOT/bkpbootmgfw.efi


If that one doesn't work, change bpkbootmgfw.efi to bootmgfw.efi and try that one.

Tried, but no: invalid efi path. – Yoeri Coune Sep 16 '13 at 18:04

Well, what finally did it: reinstall of windows 8!
