I installed Ubuntu 18.10 on a laptop. When I opened Gparted I saw this little partition and do not know what it is (see image). Gparted also has a warning about it:
Unable to read the contents of this file system! Because of this some operations may be unavailable. The cause might be a missing software package. The following list of software packages is required for fat32 file system support: dosfstools, mtools.
fdisk has it as:
/dev/nvme0n1p1 2048 6143 4096 2M BIOS boot
What is this partition, why is it there and do I need it? I have never noticed such a partition before.
Update: I find this hard to understand even after having read up on it. I add my disk layout here:
sudo parted -l /dev/sda Model: SAMSUNG MZSLW1T0HMLH-000L1 (nvme) Disk /dev/nvme0n1: 1024GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 3146kB 2097kB fat32 bios_grub 2 3146kB 543MB 540MB fat32 boot, esp 3 543MB 1024GB 1024GB btrfs
I guess I have a gpt partition so therefore I have the bios_grub partition? This is a relatively new install of 18.10 and I wonder why the partition table is gpt?
