    Default Will my BIOS access USB3? What about W10 on SATA?

    D-day is approaching and I'm thinking about installing W10 from USB. I currently run Win7

    Questions:

    (1) is my BIOS dated April 2015 likely to support W10 installation from a USB2 stick (or DVD) on a USB3 port?

    (2) same question but support for a USB3 stick (on a USB3 port). I might as well use the faster version if it will work

    (3) when the BIOS passes control over to W10, will the USB3 ports be usable at that point without installing drivers?

    (4) is it possible to install W10 from fresh by putting Microsoft W10 Build XXX on a SATA drive beforehand and having BIOS install from that? I have a blank 120GB SSD doing nothing (not needed for OS)

    I ask these questions because my MB is a bit unusual in not having any USB2 ports on the back. When I built my rig 6 months ago I turned it on to check the CPU fan and to my surprise it loaded Win7 from the old MB installation. I left it there because I wanted Win7, but none of the USB3 ports worked. A problem, because my DVD is USB and Ethernet didn't work either so I had no way of getting drivers. (I eventually got everything going via SATA)

    The issue I'm struggling with is that when BIOS passed control over to Win7, surely Win7 should have been able to drive the USB3 ports in USB2 mode? There's something I don't understand, and I'm wondering if a native USB2 port is essential? There's a header for USB2 but my case ports are USB3 connected to a USB3 header. (I might have to use an old USB2 case connector temporarily. I think I've got one somewhere)

    Win7 : install the USB3 driver . Its that simple (usually) .
    You may have some driver issues since Win7 was from an install on another motherboard/system

    Win10 : should allready have that USB3 driver so should just work....
    If in doubt, download win10 network drivers and save to usb first (just in case)

    ... all assuming there isnt a hardware fault other weirdness .

    That's fine if USB2 is working

    With Win7 it doesnt support USB 3 when you install it. So it can, or will be hard trying to install it using a USB 3 port. Use a USB 2 port.

    Some people have managed to install it by cancelling it then going back to the install. If you changed the USB in the BIOS to legacy then it may work in a USB 3 port

    Altho if you've got the ISO this Intel program will inject USB 3 drivers into it

    Win10 supports USB 3 natively (and when you use a USB 3 port to install it). Win7 does not

    The BIOS isnt the prob when you install Win7, (as above it doesnt support USB 3 natively. There are no USB 3 drivers in the ISO or the DVD), when you install it.

    If you brought Win10 it will install fine. If you upgrade from 7 or 8, make sure it's activated first then upgrade. Then you can do a clean install of 10. It should stay activated

    Should be fine with SATA. I've got Win10 on an SSD. If its 64 bit enable secureboot in the BIOS before you install Win10
