The tools available for Arch Linux are listed in the #Partitioning tools section. To find out the disk partition scheme and the system partition, use fdisk as root on the disk you want to boot from: Check for an existing partition. This … The partitioning scheme is stored in a partition table such as Master Boot Record (MBR) or GUID Partition Table (GPT). If you are installing Arch Linux on an UEFI-capable computer with an installed operating system, like Windows 10 for example, it is very likely that you already have an EFI system partition. Partition tables are created and modified using one of many partitioning tools.
