How would you prepare for it?
Same as you would for any full OS install.
Have your OS install and license key ready
Have installations, serial numbers, usernames, passwords...all saved elsewhere.
Have all your personal data that lives on that drive saved elsewhere and offline.
Find and download all the relevant drivers.
Your browser favorites, stuff like that.
All that may not be needed. It may boot up perfectly.
But better to have it and not need it, rather than need it and not have it.
