If you need to boot to Easy2Boot under a VM on a system that does not have RMPrepUSB or a VM Manager such as Virtual Box or VMWare already installed, you can keep a copy of MobaLiveCD.exe on the E2B drive.
MobaLiveCD.exe will boot to QEMU (a CPU and system emulator) and then boot the QEMU virtual machine from the E2B USB drive.
As an alternative, you can download and unzip the BOOT_ME_USING_QEMU.zip file from the E2B Alternate Downloads Area to your E2B USB drive (it must be on the USB drive and not your internal hard disk) and then double-click on the BootUSB.cmd file to boot from the USB drive under QEMU. This should only be used to boot to the menu system or select .imgPTN files however as it does not create a virtual hard disk, does not lock the drive like RMPrepUSB does, and uses a fixed memory size of 500MB.
I may add this QEMU folder into the E2B download file, if anyone thinks this is useful, as it is only an extra 1MB.
