VirtualBox - Change UUID

" Cannot Register the hard disk ‘harddisk_2.vdi’ {93476107-f8f8-44ae-83b9-e6be00432ab8} because a hard disk ‘harddisk.vdi’ with UUID {93476107-f8f8-44ae-83b9-e6be00432ab8} already exists. "

You cannot just copy hard drive files and expect them to work on the same VirtualBox instance. You need to change the UUID, like this -

C:\>cd\program files\oracle\virtualbox

C:\Program Files\Oracle\VirtualBox>vboxmanage internalcommands sethduuid "c:\!rd
UUID changed to: cb850c97-570f-4051-bebb-92951a90e6cf
