Ventoy is an open-source tool to create a 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 image files to the USB drive and boot it. You can copy many image files at a time and ventoy will give you a boot menu to select them.

How to install ventoy in USB drive
Download the installation package, like ventoy-x.x.xx-windows.zip, and decompress it.
Run Ventoy2Disk.exe, select the device, and click the Install or Update button.

You just need to install Ventoy once, after that all the things needed are to copy the iso files to the USB. You can also use it as a plain USB drive to store files and this will not affect Ventoy’s function.
Copy Image files
After the installation is complete, the USB drive will be divided into 2 partitions. The 1st partition was formatted with the exFAT filesystem (You can also reformat it manually with NTFS/FAT32/UDF/XFS/Ext2/3/4 … See Notes). You just need to copy iso files to this partition. You can place the iso/wim/img/vhd(x) files any where. Ventoy will search all the directories and subdirectories recursively to find all the image files and list them in the boot menu alphabetically. Also, you use plugin configuration to tell Ventoy only to search for image files in a fixed directory (and its subdirectories).
