Hey there! Are you attempting to dualboot or just install arch only on your computer/laptop?

Do you want to dualboot on the same drive?
For me normally what I do to prevent issues at least for me I unplug my windows drive and do archinstall with only the drive I want to install it on
I am not sure I am at a loss then

Well you don't need to unplug the drive lol
Also if you're doing a manual install there's no reason to do that (and probably not any reason if you're using archinstall either)
I can help with any questions you have

This is a good place to start
