Creates a Microsoft Reserved (MSR) partition on a GUID Partition Table (GPT) disk.
For examples of how this command can be used, see Examples.
Syntax
create partition msr [size=<n>] [offset=<n>] [noerr]
Parameters
| Parameter | Description |
|---|---|
|
size=<n> |
The size of the partition in megabytes (MB). The partition is at least as long in bytes as the number specified by n. If no size is given, the partition continues until there is no more free space in the current region. |
|
offset=<n> |
The offset in kilobytes (KB), at which the partition is created. If no offset is given, the partition is placed in the first disk extent that is large enough to hold it. |
|
noerr |
For scripting only. When an error is encountered, DiskPart continues to process commands as if the error did not occur. Without this parameter, an error causes DiskPart to exit with an error code. |
Remarks
|
Caution |
|
Be very careful when using this command. Because GPT disks require a specific partition layout, creating Microsoft Reserved partitions could cause the disk to become unreadable. |
- On GPT disks that are used to start Windows XP 64-Bit Edition,
the EFI System partition is the first partition on the disk,
followed by the Microsoft Reserved partition.
- GPT disks used only for data storage do not have an EFI System
partition; the Microsoft Reserved partition is the first
partition.
- Windows does not mount Microsoft Reserved partitions. You
cannot store data on them and you cannot delete them.
- A basic GPT disk must be selected for this operation to
succeed. Use the select disk command to select a basic GPT
disk and shift the focus to it.
Examples
To create a Microsoft Reserved partition of 1000 megabytes in size, type:
create partition msr size=1000
