I used to this without any problems on my Thinkpad when I was running Windows 7. It was pretty straightforward then.
- Download the ISO from Microsoft Store
- Download Windows 7 USB/DVD Download Tool
- Create bootable USB
For some reason, with my Sony Vaio and Windows 8, sometimes it doesn't recognize the USB drive or it gives me this silly error message.
Files copied successfully. However, we were unable to run bootsect to make the USB device bootable. If you need assistance with bootsect, please click the "Online Help" link above for more information.
I tried a couple of other utilities and found this one to work EVERYTIME and it gets the job done really quickly too. So yeah, get Rufus whenever you need to create bootable USB drives. I'll be using this for all my Linux distro images too.
