Windows 10: Two operating systems

When I restart an older W10 laptop I own, after the manufacturer logo I see a light blue screen with "Choose an Operating System" at the top. Below that it has two choices.


Windows 10

On volume 5


and


Windows 10

On volume 3


I always select the first one and have never had a problem. I'm not sure how or why it started, but it has been happening ever since I reinstalled Windows years ago. It may have been an upgrade to W10 from an earlier version, I don't remember.


I am giving the computer away and would like to clean things up. I would assume this duplication of the OS must be using up more space than necessary? Should I worry about it and if so, how to fix it?


Also, can I reinstall Windows from scratch to wipe the computer?

Are you able to follow them?

need list of usb bootable Operating Systems

I am looking for a good list of operating systems you can run from a usb or dvd.

If not a list, then folks can just post their top picks.

I want these to run from the usb/dvd without installing on the system or getting in the way of the system that exists on the hard drive.

Thanks in advance.
