Is there a tool that could be used off an already-formatted USB drive? I have my Win7 Ultimate x64 installation on a 64GB thumb drive, with a couple of Linux images and Hirens' BootCD as well, and a a good clone/migration tool would be great.
I've already got a bootable USB (Easy2Boot), I just need a tool to put on it, it will run ISO's.You can create a bootable USB with Macrium Reflect and MiniTool partition Wizard.
I used Easy2Boot, which worked like a charm.I don't know what you used to make your multiboot drive but you might see what Yumi at pendrivelinux.com has in its support list.
