The "install system" process you're asking about starts with downloading the Yosemite installer and that's over 5GB in size. Depending on how fast your internet connection is, that can take quite a while, and that's assuming the server that's delivering it to you can run faster than your internet connection (they can sometimes get very busy). It's only after the download is complete and is verified that the actual installation even begins.

Just what is listed on the the screen for what is is current happening?

Sometimes a glitch happens and you have to start over.

If you have a good fast Internet connection, and the download seems to predict far too long for that download, cancel it the download again. Often the next download will proceed at a more reasonable pace.

Some of the fastest Internet connections can complete that download in a predicted one hour.

If you use Ethernet, it will be a lot faster.

On another Mac download the Yosemite installer from the Mac App Store. Do NOT run the installer.

Download this

DiskMaker X

and use it to make a bootable USB install device.

Boot the MacBook from that USB device bt depressing and holding the Option key during boot up and then section the USB device fro booting

No, you need a Mac to download Yosemite AND to make a bootable USB device

You bought a used machine that was not properly erased to its original settings and OS.

Since you've never purchased (downloaded using your own Apple ID) Yosemite you can't use internet Recovery to restore it. If it originally shipped with Lion then that must be installed before you can download Yosemite.
