Just a small heads up, some motherboards, especially MSI ones, have picky firmwares and absolutely require the bootloader's EFI executable to be copied to "EFI/BOOT".
If the file is not there, the firmware simply won't find any bootable drive!
I use a MSI motherboard so whenever I install Gentoo, I make sure I copy GRUB's "grubx64.efi" file to "/boot/EFI/BOOT/BOOTX64.EFI"
I don't know if renaming the executable as "BOOTX64.EFI" is absolutely necessary, but I do it just to be safe.
If there is no "/boot/EFI/BOOT" folder, you must create it.
I can't forget the dispair I felt after spending 6+ hours fresh installing only to find out the newly built OS doesn't boot...  
Note: This only happened to me once, the first time I tried installing Gentoo.

efi/boot/bootx64.efi is the default path for uefi firmware to find a bootable efi binary if no valid boot entry is presented. I'd think it's more likely you have misconfigured grub. Because then your computer is not capable of dual booting two systems using efi stub, no? This shouldn't happen on modern hardware...

No, you cant misconfigure grub here.
You have only two ways for this problem:
1. Creating an UEFI boot-entry with "efibootmgr -c ..." went wrong (this will be done internal when installing grub2; or you can do it by yourself), or
2. The mainboard is really doing wrong things, like e.g. ONLY boot an "efi/boot/bootx64.efi" (like this MSI) |

Last year, when the default partitioning scheme in the handbook was four partitions with a bios partition in front of the uefi partition, I tried that for an Asus X570 board. It would not recognize it. Reinstalling without the bios partition worked.
I am also glad that the handbook has been updated regarding partitioning. |
