No overwrite boot partition.[SOLVED]

Hello, grettings all

Im starting my journey with arch, and yesterday i've installed arch, but when i installing grub with command:

grub-install /dev/sda

i get error becouse i wasnt have bios bootable partition so i make they and mount at /mnt/bios, but after install, after all, folder /mnt/bios is empty, but grub is installed, so i had delete that bios boot partition already, but this partition might be need for me in future ? why installation dont overwrite mounted folder ? Whats going on with that partition at all ? ;p

I have hope for some answers, and again grettings users o/

Re: No overwrite boot partition.[SOLVED]

A BIOS boot partition is required on GPT-type disks to hold GRUB.

This type of partition does not (should not) have a filesystem so you should not be able to mount it.

Which guide have you been following to install Arch?

Either:

You make 2 MB BIOS boot partition (not referring to /boot) without a file system as said above. Only mark it as "BIOS Boot Partition" during setup.

OR

Switch to syslinux instead of grub as boot loader. It does not need BIOS boot partition.

Yes it does.

If the disk has a GUID partition table a BIOS boot partition is required for booting a non-EFI system; this is independent of the bootloader type.

Read the links I posted above.

Yes it does.

I had it without BOIS boot partition some time ago on vbox using syslinux and also from Arch Wiki Beginners Guide:

Partition schemes
<....>
Depending on the motherboard's firmware interface, the chosen #Partition table types, and in some cases also the chosen boot loader, the following additional partitions must be created:
        BIOS/MBR: no additional partition required.
        BIOS/GPT:
            If using syslinux: no additional partition required.
            If using GRUB: one BIOS Boot Partition.

It's clear I think.

My apologies, you are quite correct.

@Head: No worries.

@X_user: If you delete BIOS boot partition, Grub will not boot (... but never tried that). Please mark thread "Solved" f you got answers and create separate for other issues.
