Typically, these standard partitions are designated as primary partitions. Windows does not support the GUID partition table (GPT) file system on BIOS-based computers.Īn MBR drive can have up to four standard partitions. When you deploy Windows to a BIOS-based device, you must format hard drives by using an MBR file system. If you use a custom partition layout on Windows 10 or Windows 11 for desktop editions (Home, Pro, Enterprise, and Education), update the Push-button reset recovery script so the recovery tools can recreate the custom partition layout when needed.
