Creating a bootable USB from an ISO is done for several reasons. Mainly, the process is a life saver when an optical drive is broken and a new program or version of windows needs to be installed. Otherwise the process is used to speed up installation of software through the USB port. Creating a bootable USB drive from an ISO is done by following a few easy steps.
Download software that makes bootable USB drives from an ISO. WinToFlash and UNetbootin are both options included in the Resources section. The software will automatically convert iso files to a USB drive and make them bootable.
Open and install your chosen software. The software will be a click-through installation where pressing next a couple times will have you ready to go.
Plug in the USB flash drive and check what drive it is listed as in "My Computer."
Run your chosen software and specify the paths. There will be two sections to choose from. In the upload or source section browse for the ISO file being converted. For the second section, select the path or destination (USB drive) the ISO is being transferred to.
Click "Next" and let the program create a bootable USB drive from the ISO file. It may take some time depending on the size of the ISO file. When the process is done you have a bootable USB drive with your ISO file.
