Why same image is bootable from DVD and not from USB, what I need to do to make it bootable-usb of the same iso image?

It depends on what you're trying to boot. If you're trying to boot something that's Linux, UNetBootin is great. For Windows 7, give the official Windows 7 USB/DVD download tool a whirl.

As the question sawdust linked explains, you will need some kind of boot loader for images 'burned' to a USB drive. Both these utilities will take care of that. (Anyone know of a solution for pre-Vista installs?)

  • I think UNetBootin works for anything, not just linux. It includes an automatic download feature for some linux distros, which probably confuses people as the GUI is a bit vague. – jiggunjer Dec 30 '15 at 03:14
