GRUB2 won't load unless I keep pressing the F3 key

Hello.

So I have a weird problem.

I'm using a Samsung QX-412 laptop (Core i5 + Intel HM65 chip7) with GRUB2 installed in EFI x86_64 mode.
Using efibootmgr I placed grub as the first boot method but unless I keep pressing F3 right after POST the screen just flickers and grub doesn't load.

More information:

If I put a USB pendrive it just goes straight to that (It's the second boot method)
During grub-mkconfig it complains about a file /boot/grub/video.lst not existing
Sometimes the booting process hangs on "Loading initrd ramdisk"

Can someone give me some pointers? I'm clueless, this is my first time working with grub2 and UEFI.

Re: GRUB2 won't load unless I keep pressing the F3 key

Bad news everyone.

1)
Moved grub.efi to /EFI/boot/bootx64.efi but the system behaved the same.

2)
Moved grub.efi to the EFI partition root but apart from the necessary F3 key punching which stayed the same, the system hangs on "Loading initial ramdisk" became worst.
I was only able to boot the system by incorrectly typing the kernel file name and pressing F10 (to boot), a warning "Press any key..." appeared, I pressed Enter and archlinux started booting, how odd is that?

Seriously, GRUB2 seems like a mess, wasn't the whole point of UEFI to simplify things? sad

I'm going to try that.

Just for future reference

Damn, you have lots of entries in UEFI Boot Manager.  Can you try setting 

Boot000B  GRUB2 HD(1,800,32000,defc8087-86c3-4611-af5a-a694bbd1d9fc)File(\EFI\grub\grub.efi)

as default using efibootmgr?

But the F3 issue seems to be like firmware bug. Did you update the BIOS/UEFI?

Re: GRUB2 won't load unless I keep pressing the F3 key

Found a solution, by placing grub.efi in /EFI/Boot/bootx64.efi and booting from the hardisk in BIOS I was able to solve the F3 key problem.

However, the "File not found" problem still persists, pressing Enter allows the system to boot.

The "File not found" error occurs because grub.efi (bootx64.efi) thinks that /EFI/boot is its prefix dir and tries to load its modules from that dir. To correct this, create /EFI/boot/grub.cfg and add the below code to it

set prefix=(${root})/efi/grub
configfile ${prefix}/grub.cfg
