I've installed ubuntu gnome and it won't let me run the grub2 boot loader from my hard drive when I start the computer and then would try to start using a lan network and would restart the boot process again. I burned disk with grub2 using http://www.supergrubdisk.org/super-grub2-disk/

If I boot off of that disk I can select ubuntu and boot it but I can't boot without this disk because the default grub2 boot loader will not start on boot.

I'd like to be able to boot my computer without this disk.

  • You might try turning UEFI Secure boot off in UEFI. But make sure you are booting in UEFI boot mode, not BIOS/CSM/Legacy mode. You somehow installed a grub BIOS boot loader to gpt's protective MBR, but it will never work. Just do not boot in BIOS mode and the incorrect grub will never be seen. – oldfred Oct 15 '16 at 20:56
  • how do i do that, im looking it up not but i cannot find a simple explanation. – 3rdParty Oct 16 '16 at 1:32
  • plus i no longer have windows installed so i can't edit the UEFI from there – 3rdParty Oct 16 '16 at 1:35
  • i tried to run systemctl reboot --firmware-setup and it gave me this error: "Cannot indicate to EFI to boot into setup mode: No such file or directory" – 3rdParty Oct 16 '16 at 1:42

I fixed this by reinstalling grub2 from boot repair. First it gave me an error saying

Failed to open /EFI/BOOT/grubx64.efi - Not Found 

I then realised I could go into the foler /boot/efi/EFI/ubuntu/ to find the GRUB file where it had been reinstalled and then copy /boot/efi/EFI/ubuntu/shimx64.efi, /boot/efi/EFI/ubuntu/grubx64.efi and /boot/efi/EFI/ubuntu/grub.cfg to the folder it said it could not find the files in which was /boot/efi/EFI/BOOT/

After I did that my computer will now correctly boot GRUB when booting from the HDD.

Make a bootable USB of Ubuntu, boot from it then. Use the commands given in this link Repair/Reinstall/Restore Grub
