Hello,
The machine that you are restoring to should have similar hardware.
Please see the technote below which will help you further regarding this:

Also please note regarding your second question:
It will overwrite the drivers for the SATA controller when you do a restore for entire system.
Also if you restore and there is a driver conflict then it can cause Blue screen for which you might need to contact Microsoft.
Thanks,
