After learning how to install medicat i discovered ventoy. With ventoy you can copy and paste how ever many bootable iso files you like into it and run them all from the same drive/partition from a selectable boot menu. It's amazing, I won't be using dd anymore for boot disks.
Careful where you point that thing. I unintentionally disrupted someone's life by introducing them to ventoy. Now they have been distrohopping like crazy because of how easy it is.
