This creates a bootable USB. It handled Windows 7 + Windows 10 and Linux Mint 18.3.
I suppose it will accommodate other Linux live systems also. You need to select FAT32 for UEFI bios installs. I normally used Yumi for multiboot but it can't accommodate multiple Windows installs.
I also like the test boot function with QEMU.
I did add advanced setting to use custom names for Windows boots . . .
I tried "syslinux" but it didn't seem to work so had to redo with linux ISO option. I probably don't understand how to use the syslinux option.
