I have used pc for 7 months without errors. I have a `gpt` partition table and a Bios. During my installation I made a 2 Mb `grub_bios` partition. This evening using `gparted` I noticed that that partition is marked as `unknown` and bytes are used.

Now, having only Ubuntu on this pc I don't get errors, but If I would install an other OS, could I get errors?
In every case, have I solve this problem (how)?
