However, with the introduction of Windows XP, FDISK was replaced with the graphical Windows Disk Management utility and Diskpart command. With FDISK, you're able to delete, create, and partition your hard drive. The related FixParts utility fixes some common problems on Master Boot Record (MBR) disks. GPT fdisk is a disk partitioning tool loosely modeled on Linux fdisk, but used for modifying GUID Partition Table (GPT) disks. FDISK is the oldest and most classic disk partition tool that is included in all versions of MS-DOS and earlier versions of Windows system.
