Using a previous VHD in a new PC

[pippo1959]

Hi all, I'm asking the following question because, after searching the forum for more than 2 hours, I could not find the answer...
What happens...I used a virtual machine on a win7 32 laptop...both laptop & hard drive died...
So I installed Vbox on a new laptop, always win 7 32, and I tried to reuse the backup of the above mentioned virtual machine (it's a win xp guest).
But, when I tell Vbox to use this VHD, i receive this message (ok, it's italian language, but I'm italian...):
Apertura non riuscita del disco fisso C:\Users\ENC-IT\.VirtualBox\Windows XP Mode SP3.vhd.
Parent medium with UUID {c80aca75-02d9-f647-a457-be6fa88c8e1a} of the medium 'C:\Users\ENC-IT\.VirtualBox\Windows XP Mode SP3.vhd' is not found in the media registry ('C:\Users\ENC-IT/.VirtualBox\VirtualBox.xml').

could not open virtual hard drive etc etc etc...

Anyone who experienced the same problem could help me ?

I will appreciate any useful information.
Thanks a lot...
Pippo

Yes, in general you can use existing VHDs in new VMs.

However, a couple of caveats seem to apply to you. (1) The error message means that the VHD you have there is not stand-alone, it's a differencing or delta image relative to a base image which I presume is missing. Even if you replace the missing base image and work out how to merge them I think you'll then encounter problem (2) The Win7 "Window XP Mode" activation check will prevent it from running on any PC except the original Win7 PC.
