How can I boot Lenovo X1 Carbon 2014 from a USB thumb drive? It has Windows 8.1. And I have tried
- Disable Secure Boot in the BIOS setting.
- Create the bootable USB drive using Windows 7 USB/DVD download too (tool?).
- Change the boot order to have the USB drive as #1.

but when I boot my laptop up, it does not boot from the USB drive. It always goes back to Windows 8.1.
Does anyone know how to get Lenovo X1 Carbon to boot from USB drive?
