Is it possible to strip a Windows computer of its OS, and put a hypervisor on it?

I have a few laptops at work laying around and I've thought about putting it to use.

For the past few days I've been trying to put Promox, through Rufus, on some computers and I haven't been successful.

I've gone through about 6 USB's, and most of em have ended up corrupted while using Rufus. A couple of em didn't end up corrupted but I can't get it to boot up on the laptop.

Anybody have any suggestions or advice?

I've tried etcher and the other USB installer mentioned in the Proxmox docs, but I can't even see the iso images when I use those.
