I installed GNOME on my Windows 10 PC so that I can dual boot them. Originally I couldn't boot to GRUB at all, it would just boot to Windows. I also noticed I can't access UEFI firmware through Advanced Restart (yes, I have checked and my computer is UEFI). So I cannot disable secure boot or alter the boot order. I did some searching, and I found this command on another AskUbuntu post, so I ran it:

`bcdedit /set {bootmgr} "path\EFI\ubuntu\shimx64.efi"` in command prompt.
