virtualbox.org

Good evening, I installed VirtualBox and I associate a virtual hard disk.
but I have a problem; if I make a copy of this virtual hard disk and rename it, then I can not bind it to the same virtual machine (instead of the other) it in a new virtual machine.
It gives me the following error:

Apertura del file del disco fisso C:\Users\Andrea\Documents\Macchine Virtuali\Immagini HDD\WIN 7_PRO_32bit_Omron\WIN 7_PRO_32bit_Omron.vhd non riuscita.

Can anyone help me?
Thank you

You should clone instead of copying. Each guest must have a unique UUID.

Ah, then I try to clone.
Thank you Perryg!
