Issue

If you are creating virtual hard drives from VirtualBox, you will probably run into the following error.

Failed to create the hard disk storage C:\xuan\vbox\vm\Debian\debian\debian.vhd.

Cannot register the hard disk 'C:\xuan\vbox\vm\Debian\debian\debian.vhd' {01c18f8b-52e0-463a-8b4c-f756f3325cbe} because a hard disk 'C:\xuan\vbox\vm\Debian\debian\debian.vhd' with UUID {8ccc5b02-3751-4168-af99-207aeddf7bc0} already exists.

The most common cause of this problem is that you detach your VHDs from your virtual machine without removing it from the central registry, Virtual Media Manager. Then, you proceed to create a new VHD with same name. Therefore, VirtualBox will complain that the same UUID already exist in Virtual Media Manager.

Solution

Navigate to File > Virtual Media Manager and then remove the existing VHD. Then, you can now add a new VHD with the same name.
