GPT Partition Entry.

◆ PartitionTypeGUID
| EFI_GUID EFI_PARTITION_ENTRY::PartitionTypeGUID |
Unique ID that defines the purpose and type of this Partition.
A value of zero defines that this partition entry is not being used.
Definition at line 93 of file UefiGpt.h.
◆ UniquePartitionGUID
| EFI_GUID EFI_PARTITION_ENTRY::UniquePartitionGUID |
GUID that is unique for every partition entry.
Every partition ever created will have a unique GUID. This GUID must be assigned when the GUID Partition Entry is created.
Definition at line 99 of file UefiGpt.h.
◆ StartingLBA
| EFI_LBA EFI_PARTITION_ENTRY::StartingLBA |
Starting LBA of the partition defined by this entry.
Definition at line 103 of file UefiGpt.h.
◆ EndingLBA
| EFI_LBA EFI_PARTITION_ENTRY::EndingLBA |
Ending LBA of the partition defined by this entry.
Definition at line 107 of file UefiGpt.h.
◆ Attributes
| UINT64 EFI_PARTITION_ENTRY::Attributes |
Attribute bits, all bits reserved by UEFI Bit 0: If this bit is set, the partition is required for the platform to function.
The owner/creator of the partition indicates that deletion or modification of the contents can result in loss of platform features or failure for the platform to boot or operate. The system cannot function normally if this partition is removed, and it should be considered part of the hardware of the system. Actions such as running diagnostics, system recovery, or even OS install or boot, could potentially stop working if this partition is removed. Unless OS software or firmware recognizes this partition, it should never be removed or modified as the UEFI firmware or platform hardware may become non-functional. Bit 1: If this bit is set, then firmware must not produce an EFI_BLOCK_IO_PROTOCOL device for this partition. By not producing an EFI_BLOCK_IO_PROTOCOL partition, file system mappings will not be created for this partition in UEFI. Bit 2: This bit is set aside to let systems with traditional PC-AT BIOS firmware implementations inform certain limited, special-purpose software running on these systems that a GPT partition may be bootable. The UEFI boot manager must ignore this bit when selecting a UEFI-compliant application, e.g., an OS loader. Bits 3-47: Undefined and must be zero. Reserved for expansion by future versions of the UEFI specification. Bits 48-63: Reserved for GUID specific use. The use of these bits will vary depending on the PartitionTypeGUID. Only the owner of the PartitionTypeGUID is allowed to modify these bits. They must be preserved if Bits 0-47 are modified..
