Z70 USB 3.0 didnt recognize by bios



My original hdd died a few weeks ago and i bought a external hdd with usb 3.0 compatibility (1 TB). I installed windows 10 in the usb hdd (full OS, not only the iso to boot installer). I can start and work the W10 from the external hdd but only from my usb 2.0 ports (after top it in the bios uefi boot list). If i change the hdd to the other usb 2.0, all works fine, but if i change to the usb 3.0 the bios didnt show it. When i initialize from the usb 2.0 i can work with the 3.0 without fails (any storage device, wifi amplifier, mouse). From another emergency SO usb boot (hiren) i checked that the new hdd works in the usb 3.0.


I need to know how to activate the boot option from the usb 3.0, and i want to suggest to change your bios politics to leave the final user to change everything in the product that they bought without need of a Computers PHd. and collect 300 shiny pokemons.

Hi Sidasaurus!


Welcome to the Community,


Try installing the Chipset Driver directly from our support website, (Enter Serial Number>Drivers and Software>Chipset)


Also, make sure Secure Boot under Security Tab in BIOS is disabled. You can follow the guide in the link below on how to access BIOS,


After that, press Fn+F10 to exit saving changes.


Update us how it goes.
