Hello jo-papi,
Can you, please give me more information regarding the cloning process? Are you just changing the hard drives of the PCs or you are trying to renew the whole PC – I mean with the motherboard changed and then try to install the HDD? Please, explain, as I could not quite catch the detailes of the situation. If you want to make an image from one desktop to many other PCs, you could find issues during the starting process as the PC of origin has different hardware settings than the others. A clone would work perfectly if you copy the image of a hard drive and transfer it to another HDD.
Cheers.
