How Do I Mount Iso
YUMI uses a small menu when the USB is booted to let you select the ISO/OS to boot from the USB drive. Choose your USB drive in step 1, choose the 'Windows Vista/7/8 Installer' option for Step 2 (it's near the bottom of the drop-down menu), and point it to the Windows 7 ISO file in Step 3. YUMI should take care of the rest. OSFMount is a free software to mount BIN files as virtual drives. Along with BIN files.
