You can cancel the current one. And for making a bootable installer. Make sure you have a USB that can be formatted. https://support.apple.com/en-us/HT201372I do not think I created a bootable installer I just clicked on the install Monterey in the application folder? does installing it from a bootable disk wipe your information or just updates the OS? If so how do I create the bootable disk? Thanks for the help!
Sorry for my ignorance
Also on the command. you will see for example it will have " --volume /blablabla/bla " . I recommend adding --downloadassets too so " --downloadassets --volume /bla/bla " so that it'll download the necessary things when it's making the installer..
To boot to the installer you can just look at the link above. It shows how to boot into it too
