A single partition of type EEh, encompassing the entire GPT drive (where "entire" actually means as much of the drive as can be represented in an MBR), is indicated and identifies it as GPT. Operating systems and tools which cannot read GPT disks will generally recognize the disk as containing one partition of unknown type and no empty space ...
In the context of GPT on a BIOS-based computer, a BIOS boot partition is similar in some respects to the EFI system partition, which is used by systems based on EFI. The EFI System partition holds a filesystem and files used by the UEFI, while the BIOS boot partition is used in BIOS-based systems and accessed without a filesystem by holding raw ...
In such systems a menu at startup gives a choice of which OS to boot/start (and only one OS at a time is loaded). This is distinct from virtual operating systems, in which one operating system is run as a self-contained virtual "program" within another already-running operating system. (An example is a Windows OS "virtual machine" running from ...

The operating system may not automatically assign a drive letter to the volume. In Microsoft operating systems , when using basic disk partitioned with GUID Partition Table (GPT) layout, a basic data partition ( BDP ) is any partition identified with Globally Unique Identifier (GUID) of EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 .
The system partition is the disk partition that contains the operating system folder, known as the system root. By default, in Linux, operating system files are mounted at / (the root directory). In Linux, a single partition can be both a boot and a system partition if both /boot/ and the root directory are in the same partition.
A Microsoft Reserved Partition (MSR) is a partition of a data storage device that uses the GUID Partition Table (GPT) layout. The Windows operating system uses this partition for compatibility purposes. No meaningful data is stored within the MSR.
From the perspective of the BIOS, the action of the MBR loading a volume boot record into RAM is exactly the same as the action of a floppy disk volume boot record loading the object code of an operating system loader into RAM. In either case, the program that the BIOS loaded is going about the work of chain loading an operating system.
