YUMI multiboot usb to ISO file? I have been using a YUMI made multiboot USB for about 3 years now and as I was tinkering in my VirtualBox it hit me, can I make an ISO from that YUMI multiboot USB? I made an ISO from it via PowerISO but it would not boot. I usually do this with ImageBurn but the etfsboot.com that I use isn't seen in the YUMI multiboot USB contents... Any ideas guys? Thanks a lot!
