I have an HP Pavilion Sleekbook 14 laptop that I have installed Ubuntu 12.10 dual boot with the original windows 8. I used boot-repair to get set up to boot into grub.
My issue is that I have not been able to get it to boot straight off the new efi file that was created. I have looked around the boot options in the bios screen, but it does not give me a choice for Ubuntu. The only way I can boot into Ubuntu is to press F9 when I power the system on and then manually navigate to the ubuntu efi file. This works but if I am not paying close attention, it will boot into windows.
After I finished running boot-repair, it told me to boot from sda2/EFI/ubuntu/shimx64.efi
I have seen some suggestions that I should move this file in place of the windows bootmgfw.efi, but I am concerned that I will break things and not be able to boot the windows 8 installation. While I already dislike win8 even more than win7, I do need it from time to time for a couple tasks…
