Lenovo ThinkPad T480 has no OS, repair shop wants too much for a fresh Windows install!

Hello! Like the title says, my laptop has no OS installed; I was trying to uninstall Linux (followed all steps from an online guide) and it uninstalled Windows too… I’m primarily a Mac person, so I’m not sure how to solve this.

Anyways, I went to a computer repair shop and they want $195 to reinstall Windows + drivers and updates, but the issue is, this computer only cost me $250. It’s a backup computer so it’s not urgent, but I also don’t wanna pay that to reinstall Windows.

That being said, I am, as I always have been, a MacOS first person, and I’ve never had a Hackintosh before. Is this a device I could co-opt into a Hackintosh? Can someone walk me through it?
