First off, are there data in the old Windows system that you'd like to retrieve? If yes, fire up the Linux system and save them on to an external source. That way, if you go for a factory reset, you won't have lost anything except programmes you've install since you had the laptop.

The option you're looking for is Custom and that's a new system.
