Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI The answer to this question was immensely helpful to me and my new Vaio Z3. The issue that I am having now is that after replacing bootmgfw.efi with grubx64.efi and renaming, it boots directly to grub console. I dont even get a menu where i can chose ubuntu. I tried putting a grub.cfg file next to the new bootmgfw.efi(grubx64.efi), no go? Any ideas how i can get the renamed grubx64.efi to find all the rest of the grub stuff outside of the ESP in my linux parition? Or do i have to move all grub files to /EFI/Microsoft/Boot on ESP? Thank you!
