I recently bought SanDisk Ultra USB 128GB Pendrive. I want to make it bootable (Windows to go). But when I plugged it into my laptop (Lenovo G50-80) 3.0 port it is not recogniged by Boot manger(BIOS). But when I plugged into my 2.0 port it successfully recognised.

On the other hand there is no problem in my 3.0 port because when I plugged a 3.0 external hdd into 3.0 port bootmanger successfully recognised it.

Why bootmanger not able to recognised this 3.0 pendrive with 3.0 port only?
Please help
Sorry for bad english.
