For people who like to mess around with live cds, https://ventoy.net/ let's you create a bootable USB stick where you can simply copy .iso files to, and it will let you boot from that iso.
That way you don't have to keep reformatting / preparing the usb drive.
Ventoy is a fairly common source of trouble from people trying to boot ReactOS.
It's a nice, well, toy, but its compatibility with various OSes is spotty at best. You're much better off just writing a real CD-R or USB stick with the plain image than trying to manage it via Ventoy.
Ventoy never "worked" for me for some reason. It usually gets me to the ISO selection stage of the boot process, but the image refuses to boot, quickly followed by a reboot. Am I missing a trick?
Rufus continues to be easy to use and reliable on the other hand.
