OR

Disconnect power line of existing HDD to be reinstalled .
Attach another HDD or drive , for example USB stick .
Perform a fresh install on the new unit .
After verifying that the new install is working properly ,
Shutdown the computer ,
attach power of previous HDD ,
mount it ,
copy all of the new files from freshly installed unit into previous HDD,
Shutdown the computer ,
Disconnect newly installed unit ,
Restart the computer .
It is very likely that your previous HDD will work as like newly installed .

OR

Do the reverse :

>From previous HDD , copy all of the required files to the new HDD .
Disconnect previous HDD or unit .
Continue with the new HDD or unit .

If the previous HDD is not bootable , it is necessary to continue with the
new HDD .

I am applying the second kind of steps for all my new installs .

In that way nothing is broken , even there is no back up of the files
because
nothing applied to the existing HDD .

The cost of this operation is to have a spare disk or a USB stick having
sufficient capacity .
Personally I am not using USB sticks for such operations because they may
fail unexpectedly .

Thank you very much .
