TIL about Ventoy, an amazing open source tool which allows to create bootable USB drives with multiple ISOs.
No need anymore to format the USB drive every time I need to install a new operating system. The same USB stick can store more than one ISO.
I'm currently storing GParted, Fedora, and Ubuntu images in the same USB stick. When I boot from it, I just need to select the desired image from the menu.
To add a new ISO, one simply needs to drag and drop the respective file to the USB stick.
