Not entirely correct. Depending on the laptop, you may need to slipstream the USB drivers and the Windows 7 iso on to a "bootable" thumb drive. Depending on the chipset, the Windows 7 iso may not have the correct drivers to start the install. you'll need to check the laptop manufacturer's web site to see if there's Windows 7 USB drivers for this process. You can use the the program Rufus to create a bootable thumb drive.
