Failed to open the hard disk. Cannot register the hard disk becuase a hard disk with UUID already exists. I looked all over the place to find what was causing it and finally found a fix. Of course it requires the command prompt, so open that junk up and let’s get started! **Note that I am on VirtualBox version 4.1.6 and from what I’ve read this command used to be something different a few versions ago. I think instead of setdhuuid it was setvdiuuid, but don’t hold me to that.** Open the Command Prompt Change the directory to where VirtualBox is installed (Default: C:\Program Files\Oracle\VirtualBox). Type the following: VBOXMANAGE.EXE internalcommands sethduuid pathtovirtualharddisk Note that internalcommands and sethduuid need to be lowercase. I spent more than a couple minutes trying to figure out why things weren’t working. :) Source
