Dans cette section, vous devrez choisir un format de disque à utiliser pour le démarrage et le partitionnement -- soit MBR ou UEFI/GPT. Si vous ne connaissez pas les différences entre ces options, veuillez consulter notre page Disk Formats pour un aperçu de chaque option et des compromis. En général, il est généralement sûr de choisir l'ancienne méthode de MBR pour les disques système de moins de 2 To et la plupart des systèmes PC modernes prennent en charge le MBR ainsi que le démarrage UEFI.

Mais d'abord...

Before doing anything to your disks, make sure you are partitioning the right one. Use the lsblk command to view a list of all block devices on your system, as well as partitions on these block devices:

root # lsblk
NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda             8:0    0  1.8T  0 disk 
├─sda1          8:1    0  512M  0 part 
├─sda2          8:2    0    8G  0 part [SWAP]
└─sda3          8:3    0  1.8T  0 part 
  ├─main-root 254:0    0  500G  0 lvm  /
  └─main-data 254:1    0  1.3T  0 lvm  /home

   Note

If you're not sure which disks are which, you can use lsblk -o MODEL,NAME,SIZE to show the device models matching the /dev/sd? names.

Make sure you will not be overwriting any important data and that you have chosen the correct /dev/sd? device. Above, you can see that SATA disk sda contains three partitions, sda1, sda2 and sda3, and that sda3 contains LVM volumes. If you are using an NVME disk, then you may see nvem0n1 as your disk, and your partitions (if any exist yet) will be named nvme0n1p1, nvme0n1p2, etc. If you are installing on microSD Card for Raspberry Pi, your disk will likely be mmcblk0 and partitions will have suffixes p1, p2, etc.

Once you've double-checked your target block device and made sure you'll be partitioning the correct disk, proceed to the next step.
