I partitioned mine using the Linux mint installer, tho I definitely frigged up my windows install and can no longer boot into it lol, I think I can fix it with a windows 10 install usb but haven't tried yet

I switched to mint from windows last night, best decision of my life. I was skeptical of it at first because when I tested it out booting from a bootable drive I was running into a bunch of issues, but once I committed and made an actual install on a partition all the problems went away
