In this section, you will need to choose a disk format to use for booting and partitioning -- either MBR or UEFI/GPT. If you are not familiar with the differences between these options, please review our Disk Formats page for an overview of each option and the trade-offs. 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.
But First...
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
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 sda contains three partitions, sda1, sda2 and sda3, and that sda3 contains LVM volumes.
Once you've double-checked your target block device and made sure you'll be partitioning the correct disk, proceed to the next step.
