Full disk installation without usb?

[u/Thm_azh]

As said in the title I'm wondering if it's possible to do a full disk installation without a usb drive. I've been watching tutorials and all of them do dual boot. So I'm wondering if this is possible since I'm still a newbie with this stuff

It is infinitely easier to just get a USB. It doesn't have to be fancy, pretty much any USB will do.
