[SOLVED]grub not detected by my laptop

After installing archlinux according to the wiki and rebooting grub is not appearing at all. I get the message please install an OS.

I installed efibootmgr and I  ran

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB

  and also

grub-mkconfig -o /boot/grub/grub.cfg

both grub commands finished with no error reported

my laptop model is HP Pavilion x360 Convertible 14-dw1xxx

I don't know the output of what command I should add so just tell me and I will edit the post.

secure boot is disabled

Re: [SOLVED]grub not detected by my laptop

You do have a properly marked EFI system partition mounted at /boot, right? Just a fat32 partition is not enough.

https://wiki.archlinux.org/title/EFI_sy … _partition

If you already have that, ensure that 1: your EFI system partition is correctly mounted at /boot when you run grub-install, and that 2: your motherboard BIOS is correctly configured to boot from the EFI

I have a efi partion. I set the type to efi in fdisk by pressing t selecting the number and id 1 for EFI.

My partition is mounted at boot correctly.

Hello!

I was wondering.  Have you went into the BIOS and tried to see if you could edit the EFI vars in there?

Also can you post the output of fdisk -L  so we can see what the layout looks like ??

Re: [SOLVED]grub not detected by my laptop

What's

efibootmgr -uv

as mentioned some UEFIs only allow adding NVRAM entries via their own interface, another thing you could try is reinstalling grub but add the --removable parameter to the command so that the fallback path is populated.

Re: [SOLVED]grub not detected by my laptop

The solution was to add --removable in the grub-install thank you a lot
