[Solved] BIOS does not recognize an arch disk as bootable.

I have laptop with two disks. Windows OS was installed on the first disk, and i tried to install an Arch on the second( the second disk was bought and added after installing Windows on the first). But BIOS does not recognize the second disk as bootable.

I use GRUB for booting.

Looking for a solution, I came across this info https://wiki.archlinux.org/title/GRUB#G … not_loaded
This is the response I received.

> efibootmgr -v

BIOS displays two bootable Widows OS from the first disk as options too.

Re: [Solved] BIOS does not recognize an arch disk as bootable.

The output suggests the Bios doesn't see the 2nd disk at all.

What does lsblk -f show from the arch install stick ?

Some (older) bioses can only boot from one harddisk (which one is booted from can usually be changed from within bios setup), what is brand & model of the laptop ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: [Solved] BIOS does not recognize an arch disk as bootable.

First off, you're not booting BIOS, so stop saying that. UEFI relies on those NVRAM entries that efibootmgr shows, when you run grub-install, does it show up there? What command are you using, exactly?

Installing for x86_64-efi platform.

Ooohhh... Okay, i will try to remember.

then I added UUID_encrypted_thing to /etc/default/grub

Re: [Solved] BIOS does not recognize an arch disk as bootable.

So grub-install is adding the NVRAM entry correctly, but the motherboard isn't saving it. Bad firmware. Try using grub-install's --removable option, it will install to the default loader location and the firmware may let you choose that drive to boot. This may not work with two ESPs on the same disk, though, and you censoring of UUIDs means I don't know what's where.

Just FYI:

[...]

The second command is incorrect. GRUB's configuration is expected to be under /boot/grub/.

Re: [Solved] BIOS does not recognize an arch disk as bootable.

So... I solved the problem. 


*after all necessary actions of official inst guide*
> grub-install --target=x86_64-efi --bootloader-id=GRUB --efi-directory=/boot --recheck        # I changed /boot/efi to /boot . So... That was a problem.
> grub-mkconfig -o /boot/grub/grub.cfg

P.S.
Unfortunately I did not understand how boot process works...

I'm sorry to have wasted your time. Thank you all.
