Furthermore, GPT-aware OSes may check the protective MBR and if the enclosed partition type is not of type EEh or if there are multiple partitions defined on the target device, the OS may refuse to manipulate the partition table. [10] If the actual size of the disk exceeds the maximum partition size representable using the legacy 32-bit LBA ...
English: Diagram illustrating the layout of the GUID Partition Table (GPT) scheme. Each logical block (LBA) is 512 bytes in size. LBA addresses that are negative indicate position from the end of the volume, with −1 being the last addressable block. Kbolino is the original author of this work. It is based heavily upon an image created by ...
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
According to Microsoft, the basic data partition is the equivalent to master boot record (MBR) partition types 0x06 , 0x07 (NTFS or exFAT), and 0x0B . [2] In practice, it is equivalent to 0x01 , 0x04 , 0x0C (FAT32 with logical block addressing), and 0x0E (FAT16 with logical block addressing) types as well.
The BIOS boot partition is a partition on a data storage device that GNU GRUB uses on legacy BIOS-based personal computers in order to boot an operating system, when the actual boot device contains a GUID Partition Table (GPT). Such a layout is sometimes referred to as BIOS/GPT boot. [1]
The term is most commonly associated with the MBR partition table of a Master Boot Record (MBR) in PCs, but it may be used generically to refer to other formats that divide a disk drive into partitions, such as: GUID Partition Table (GPT), Apple partition map (APM), [12] or BSD disklabel. [13]
Microsoft expects an MSR to be present on every GPT disk, and recommends it to be created as the disk is initially partitioned. [4] The GPT label for this partition type is E3C9E316-0B5C-4DB8-817D-F92DF00215AE. [2] The Microsoft-recommended size of MSR (which Windows Setup uses by default) is different for each version of Windows:
