Hi theking2,

If you mean disk label, as shared by Darrell Gorter, label.exe is the tool which could achieve this.

For Diskpart, it will only allow to Label the partition when using the format option:

See:

DiskPart Command-Line Options

And:

Sure you are right.

The GPT label is a type of GPT partition.

You can do that with diskpart:

#list disks
DISKPART> list disk
  Disk ###  Status         Size     Free     Dyn  Gpt
            
  Disk 4    Online          150 GB      0 B        *
#set focus on Disk 4 to view its metadata
DISKPART> sel disk 4
Disk 4 is now the selected disk.
#set focus on the partition that you want to label (1st partition in this example)
DISKPART> sel part 1
Partition 1 is now the selected partition.
DISKPART> SET ID=<LABEL/PARTITIONTYPE>

Well this is the world we live in And these are the hands we're given...

Hello,

Label.exe is way to change the disk label:

C:\WINDOWS\system32>label /?

Creates, changes, or deletes the volume label of a disk.

LABEL [drive:][label]

LABEL [/MP] [volume] [label]

drive: Specifies the drive letter of a drive.

label Specifies the label of the volume.

/MP Specifies that the volume should be treated as a mount point or volume name.

volume Specifies the drive letter (followed by a colon), mount point, or volume name. If volume name is specified, the /MP flag is unnecessary

Correct me if I'm wrong but label,exe will set the file system label, not the gpt label.

To find out what are the available GPT partition types, see PARTITION_INFORMATION_GPT structure.

By the way, to edit GPT labels you must boot from EFI firmware, look for EFI files on the boot disk:

bootmgfw.efi

BOOTX64.EFI

Thanks for that link to the structure. I'm looking for a way to set the name parameter. This is useful on a multiboot system as other OSses allow setting reading and modifiying these partition "names"
