Once you have made the Easy2Boot USB Flash drive (or USB HDD), you simply copy over all your boot ISOs or images (using Windows Explorer or any other method - no special utility required).
The current menu system caters for any number of Windows install ISO files ranging from XP Home to Server 2012.
You can also just copy on your WinPE ISOs, rescue ISOs and even linux LiveCD ISOs.
For Windows install ISOs, just put them in the correct folder.
All the payload files that you add are listed in the dynamically created menu system every time you boot from the USB drive.
If you make a USB HDD Multiboot drive, then for Windows Vista and later OS's , you also need to insert a USB flash drive containing 3 files at the same time as booting from the USB HDD.
For installing XP from USB using an XP ISO, E2B now automatically detects and creates F6 virtual floppy disks with the correct mass storage drivers for your system so you can install from an unmodified XP ISO straight to an AHCI/SCSI/RAID system.

Here is the Easy2Boot YouTube video to demo it and explain it all.
