Guide d'installation : Préparer le disque
Install Guide, Chapter 2 | < Prev | Next > |
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.
MBR is the traditional way of booting a PC. It works by installing executable code on the boot sector of your hard drive, which starts the boot process. When you use MBR to boot, you must have BIOS booting enabled in your BIOS, use traditional MBR partitions on your disk which are created using the fdisk
tool.
UEFI is the more modern way to boot a PC. It works using a boot loader that is built into your computer. Boot entries are created and stored in your computer's non-volatile memory. When you use UEFI to boot, you must have UEFI enabled in your BIOS, and use more modern GPT partitions which are created using the gdisk
tool.
Generally, it's usually safe to pick the legacy MBR method for system disks under 2TB in size and most modern PC systems support MBR as well as UEFI booting.
For more information on differences between MBR and UEFI, see our Disk Formats page for an overview of each option and the trade-offs.
Mais d'abord...
Avant de faire quoi que ce soit à vos disques, assurez-vous que vous partitionnez le bon. Utilisez la commande lsblk
pour afficher une liste de tous les périphériques de bloc sur votre système, ainsi que les partitions sur ces périphériques de bloc:
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|Si vous n'êtes pas sûr de savoir quels disques sont lesquels, vous pouvez utiliser lsblk -o MODEL,NAME,SIZE
pour afficher les modèles d'appareils correspondant aux noms. /dev/sd?
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 nvme0n1
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.
