 +===== Disk partitions =====
 +==== List ====
  
 +<code bash># gdisk /dev/nvme0n1 -l
 +GPT fdisk (gdisk) version 1.0.10
 +
 +The protective MBR's 0xEE partition is oversized! Auto-repairing.
 +
 +Partition table scan:
 +  MBR: protective
 +  BSD: not present
 +  APM: not present
 +  GPT: present
 +
 +Found valid GPT with protective MBR; using GPT.
 +Disk /dev/nvme0n1: 500118192 sectors, 238.5 GiB
 +Model: KXG6AZNV256G TOSHIBA                    
 +Sector size (logical/physical): 512/512 bytes
 +Disk identifier (GUID): A49CF274-51B4-4CBF-BE13-5195151DBF6E
 +Partition table holds up to 128 entries
 +Main partition table begins at sector 2 and ends at sector 33
 +First usable sector is 34, last usable sector is 500118158
 +Partitions will be aligned on 2048-sector boundaries
 +Total free space is 205869677 sectors (98.2 GiB)
 +
 +Number  Start (sector)    End (sector)  Size       Code  Name
 +   1            2048          206847   100.0 MiB   EF00  EFI system partition
 +   2          206848          239615   16.0 MiB    0C01  Microsoft reserved ...
 +   3          239616       250570751   119.4 GiB   0700  Basic data partition
 +   4       250570752       292513791   20.0 GiB    0700  Basic data partition
 +   5       498378752       500115455   848.0 MiB   2700</code>
 +The goal is to make a 16GB swap partition and the btrfs root:
 +<code bash>gdisk /dev/nvme0n1</code>
 +==== SWAP ====
 +
 +<code>
 +Command (? for help): n
 +Partition number (6-128, default 6): 
 +First sector (34-500118158, default = 292513792) or {+-}size{KMGTP}: 
 +Last sector (292513792-498378751, default = 498378751) or {+-}size{KMGTP}: +16G
 +Current type is 8300 (Linux filesystem)
 +Hex code or GUID (L to show codes, Enter = 8300): 8200
 +Changed type of partition to 'Linux swap'
 +</code>
 +==== BTRFS root ====
 +
 +<code>
 +Command (? for help): n
 +Partition number (7-128, default 7): 
 +First sector (34-500118158, default = 326068224) or {+-}size{KMGTP}: 
 +Last sector (326068224-498378751, default = 498378751) or {+-}size{KMGTP}: 
 +Current type is 8300 (Linux filesystem)
 +Hex code or GUID (L to show codes, Enter = 8300): 
 +Changed type of partition to 'Linux filesystem'
 +</code>
 +==== Save ====
 +
 +<code>
 +Command (? for help): w
 +
 +Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
 +PARTITIONS!!
 +
 +Do you want to proceed? (Y/N): Y
 +OK; writing new GUID partition table (GPT) to /dev/nvme0n1.
 +The operation has completed successfully.
