# Change UUID of VirtualBox vdi

Looking for quick way to reuse a vdi I preped with Windows XP SP3 and recent updates, I decided to duplicate the vdi with Windows Explorer. Of course, this was too simple. After attempting to create a new virtual machine which used the newly created vdi, I was presented with a nasty error along the lines of  “Failed to open the hard disk ….” and “Cannot register the hard disk C:\path\to\new\vdi with UUID {xxxx} because a hard disk C:\path\to\old\vdi already exists in the media registry (C:\path to VirtualBox.xml)

Luckily there is a simple fix for this…

Lauch a command prompt and browse to where VBoxManager.exe is located (for me this is C:\Program Files\Oracle\VirtualBox) and run the comand below

VBoxManage.exe internalcommands setvdiuuid "C:\path\to\new\vdi"

NOTE: the command has been changed to sethduuid in version 4.0.4 (thanks Isaac!). So the commad in 4.0.4 would be…

VBoxManage.exe internalcommands sethduuid "C:\path\to\new\vdi"

Which should return something similar to “UUID Changed to …”

With version 4.0.4, use “sethduuid” instead of “setvdiuuid.”

Worked on a VMDK (VMWare) disk as well (that I’m using under VirtualBox). I pulled many hairs over the last few days until I found your post – thank you.

Thanks, you just saved me a load of time This blog-post is going in my bookmarks for sure. Like others, I used the new (sethduuid) command format, with VirtualBox 4.1.12

• Adam May 4, 2012, 1:38 pm

When I try to run sethduuid on 4.1.14 using this command:

vboxmanage internalcommands setheuuid “E:\vm.vdi”

I get the following error:

VERR_FILE_NOT_FOUND at D:\tinderbox\win-4.1\src\VBox\Storage\VD.cpp(4484) in function VDOpen
VBoxManage.exe : error: Cannot open the image : VERR_FILE_NOT_FOUND

I have no D: drive and have nothing to do with tinderbox. Help!

Adam -

Can you confirm your .virtualbox file is pointing to the correct location of the vdi?

Reply
• Adam May 7, 2012, 2:33 pm

Yes, and no reference anywhere to a D: drive.

Reply
• Adam May 7, 2012, 3:43 pm

SOLVED – turns out vboxmanage is case sensitive when looking at path and file names.

Simple solution!

Thank you very much. I knew there was a solution and it was in the back of my mind. Your link was the first entry when I searched for the solution.

I had copied a cloned image into a different location (instead of the default C: drive), which, when I tried to use, caused this error.

I have use the command and I do not have any error but when i try to import the Virtual Machine Definiton file I obtain the same error. There is another way to solve the problem? Thanks.

Vito –

Check out @thegeekprophet’s reply with the reminder to update the UUID in the .vbox file. Let us know if that works!

Reply
• thegeekprophet April 10, 2013, 10:32 am

If it still complains, dont forget to update the UUID in the .vbox file for the drives you updated…

Reply
• Alex June 24, 2013, 11:57 pm

Thanks for posting this, worked perfectly for me! I needed to transfer a VBOX hard drive image to a different drive to save space which ought to be a common/easy function in VirtualBox, but isn’t. I copied the file and then changed the UUID with the command you posted. If you’re in Linux (Ubuntu, in my case), this is the command you’ll want to use:

vboxmanage internalcommands sethduuid pathto.vdi
