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!

If you're using the
grubx64.efifile from Ubuntu, in theory it should be looking on your Ubuntu/boot/grubdirectory for its support files. If it's not finding them, then I'm not sure what's wrong. If you've built GRUB from source code or installed in some other way, though, you might need to copy all its support files, as you suggest.Another alternative is to install rEFInd as
EFI/Microsoft/boot/bootmgfw.efion the ESP and leave GRUB where it is (presumablyEFI/ubuntu/grubx64.efi). With a little extra configuration (described on the rEFInd Web page), you should even be able to bypass GRUB completely, if it's giving you problems.More broadly, you may want to check out my Web page on EFI boot loaders, which includes information on boot loader installation and at least the basics of configuring all of them. (GRUB 2 is the hardest in this respect. It's only easy when the distribution installer gets it right.)
