I have 2 Windows 7 computers, both of the same spec but different makers.
Each one has similar Windows 7 installed but, obviously different keys!
Now, if I had a second drive, on the same computer, whatever the content, I could overwrite it and, changing the master, it would work.
What I would like to do is use an external drive and copy across the whole contents of my more up-to-date computer's contents, replacing the completely the secondary Windows 7 which, in any case I only use as an emergency backup for my documents.
The thing is, the secondary is virtually unusable as a main computer because, due to overheating problems the hard drive has been replaced four times. As a reserve, however it gives me immediate access to the internet in an emergency.
Responses please from anyone who has tried that or has knowledge!
I've used Acronis for many years without a single problem. However, *Fruit Bat /\0/* is correct - whilst you can clone the HDD of your second PC, this will not work on your first PC because the motherboard drivers will be different.
