TypeID (Standard 7 Package Reference)
7/8/2014
TypeID specifies the hard-drive partition type.
Use TypeID to manually specify a partition type, such as a utility partition type.
Note
Five partition types are already built in: Primary, EFI, Extended, Logical, and Microsoft Reserved (MSR). To use these built-in partition types, enter a value in the setting: Type.
Some partition types are not assigned a drive letter by default. Without a drive letter, these partitions do not appear in some common lists of devices, such as in Windows Explorer or in file dialog boxes. If you assign a letter to the partition, the partition appears in these common lists of devices.
