2.2.2.11.1.1 CHANGE_ATTRIBUTES_PARAMETERS

The CHANGE_ATTRIBUTES_PARAMETERS structure describes the attributes to change on a partition.

 typedef struct _CHANGE_ATTRIBUTES_PARAMETERS {
   VDS_PARTITION_STYLE style;
   [switch_is(style)] union {
     [case(VDS_PST_MBR)] 
       struct {
       boolean bootIndicator;
     } MbrPartInfo;
     [case(VDS_PST_GPT)] 
       struct {
       ULONGLONG attributes;
     } GptPartInfo;
     [default]       ;
   };
 } CHANGE_ATTRIBUTES_PARAMETERS;

style: The value from the VDS_PARTITION_STYLE enumeration that describes the partition format of the disk. If the disk partitioning format is MBR, the only value that can be changed is the bootIndicator. If the disk partitioning format is GPT, the only value that can be changed is the GPT attribute.

MbrPartInfo: Contains information for an MBR partition.

bootIndicator: The Boolean value that indicates whether the partition is bootable.

GptPartInfo: Contains information for a partition in a GPT.

attributes: The bitwise OR operator of attributes to change; it can have a combination of the following values.

Value	Meaning
GPT_ATTRIBUTE_PLATFORM_REQUIRED 0x0000000000000001	Partition is required for the platform to function properly.<46>
GPT_BASIC_DATA_ATTRIBUTE_READ_ONLY 0x1000000000000000	The partition can be read from but not written to. Used only with the basic data partition type.
GPT_BASIC_DATA_ATTRIBUTE_HIDDEN 0x4000000000000000	The partition is hidden and is not mounted. Used only with the basic data partition type.
GPT_BASIC_DATA_ATTRIBUTE_NO_DRIVE_LETTER 0x8000000000000000	The partition does not receive a drive letter by default when moving the disk to another machine. Used only with the basic data partition type.
