I have very little clue as to how linux works. 
The new laptop came with Endless OS rather than Windows 10, I need to keep Endless OS on the PC for warranty reasons, any way I can dual boot?

I also posted on the Linux subforum, wasn't sure where this goes.

How about taking an image of the hard drive, then reformatting it to install windows? Or just replace the hard drive in its entirety and use another one for Windows? Then if you need the OS for warranty, replace the drive with the one that the laptop came with. Either option would work well.
