SharpBoot is a small utility for creating multiboot ISO or USB. You just need to drag-n-drop some iso files inside, and it automatically adds description and category (for supported ISO files). It can use Syslinux or Grub4Dos for the menu, but you will need a tool like Rufus to put the ISO file on a USB key. You can also specify a custom background image and you an choose screen resolution between 640x480, 800x600 and 1024x768 (the background image is automatically resized to fit the screen).
