How to get the GUID of different HDD partitions?

Question

I was trying with BCDEDIT and DISKPART but that tools give me an ID that is not the GUID Note: I am testing in Windows 7

Answer 1

mountvol didn't help my in a similar case as I had two different disks containing two Windows installations (one broken), so you could not say, which is which. For that, after googling for a long time running diskpart was my rescue:

list disk
sel disk 1 #That is the "Datenträger 0", the 1TB HDD
list part
sel part 1
detail disk
detail part

giving me

Partition 1
Typ         : <HERE IS YOUR ANSWER ID>
Versteckt   : Ja #Hidden
Erforderlich: Ja #Necessary
Attribut    : 0X8000000000000001
Offset in Byte: 1048576
Volume ###  Bst  Bezeichnung  DS     Typ         Größe    Status     Info


Volume 5         Wiederherst  NTFS   Partition    529 MB  Fehlerfre  Versteck

For better visualization two screenshots of the two used tools. It has to be found out, wich of 1XXX7 and 6XXXb correspond to "Datenträger 0">EFI and "Datenträger 1">EFI respectively as well es which of 1XXXf and 5XXXf correspond to "Datenträger 0">recovery and "Datenträger 1">recovery (recovery = "Wiederherstellung").

Answer 2

Check out the output of the mountvol command:

VolumeName: Specifies the volume name that is the target of the mount point. The volume name is of the form \?\Volume{GUID}\, where {GUID} is a globally unique identifier (GUID) (for example,
\?\Volume{2eca078d-5cbc-43d3-aff8-7e8511f60d0e}).
