Ventoy ➝

From the website:

Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. With ventoy, you don’t need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly. You can copy many files at a time and ventoy will give you a boot menu to select them

I have an old MacBook Air that has been a bit finicky to get working with some Linux distributions — I suspect the machine’s WiFi and the associated drivers are to blame. I wanted to test out a bunch of distributions and Ventoy made it drop-dead simple.

I didn’t have to flash a half dozen installer images to a USB drive one at a time, I just created a Ventoy drive, transferred all of the installer images to it, and was able to test them from there.
