Using WinUSB to make bootable USB Stick
WinUSB comes with a simple GUI with minimal options to go with, here is how to use WinUSB to make bootable Windows USB from Ubuntu. You can use any Windows ISO may be for XP, Windows 7, Windows 8, Windows 8.1 or any other.
- Insert Flash Drive & Get your Windows ISO (I used Windows 10 Technical Preview) or insert the Windows CD/DVD
- Start WinUSB and, nothing else really needs to be explained.
- Select your Source, either ISO or CD Drive
- Pick your Target (USB) Device. If it doesn’t appear, hit refresh and make sure it’s mounted.
- Click on “Install” and enter your Password (required to mount devices and write directly to drives)
When you boot your computer now with the USB inserted, enter Boot Options or Select Boot Device, or you could change the order your computer boots and place your USB Device before your main harddrive. Just to note, not all computers support USB Boot devices, but nearly every computer after the year 2005 do support it.
