SSD failed, received replacement but... os is on failed drive. How will Windows run after I swap out the drive?

I have a 17 R4 that came with a 128 SSD, which is where Windows is installed, and for some reason it was set as the default drive for everything when I purchased the computer.  It filled up in a week, and 2 months after purchase it has already failed.  It's covered under warranty, but, now that I have the replacement... I don't know how to go about getting Windows on either my 1TB HD or the new replacement SSD.  I guess I'm not the nerd I thought I was.
