# Could I add GPT BIOS Boot Partition after Debian installation?

I lately mounted Debian Wheezy on a web server with 24TB of storage space (RAID 6). When I separated the large quantity I picked Manual alternative and also developed the dividing system.

When I was separating, I observed that Debian instantly developed 2 tiny dividings of 1MiB (one at starting and also an additional at end of disk). I inmediately bore in mind that this room was possibly being alloted for so I really did not bother with it and also I left them there.

Nonetheless, when I mounted a new kernel via Debian updates and also GRUB was re-installed I obtained the next mistake message:

/usr/sbin/grub-setup: warn: This GPT partition label has no BIOS Boot
Partition; embedding won't be possible!

/usr/sbin/grub-setup: warn: Embedding is not possible.  GRUB can only
be installed in this setup by using blocklists. However, blocklists
are UNRELIABLE and their use is discouraged.

Installation finished. No error reported.


This message is rather clear. Nonetheless, regardless of GRUB was appropriately mounted and also this web server is starting great, I would love to prevent this trouble.

If I execute parted I can see that this room is being recognized as free so my inquiry is: Could I make use of split to create a new dividing in this vacuum (at starting or end of disk) and also set it as GPT BIOS Boot Partition (set [num] bios_grub on)? Could it be high-risk to do it currently (after installment)?
