I completed a new build two days ago. Since then I have been trying to install Windows 10 from a bootable USB flash drive, and this flippin' system REFUSES to boot from USB.
I've tried two different USB drives. I moved each of them to different USB slots (both USB 3.0 and 2.0). I even downloaded the Windows 10 ISO a second time and created a new bootable USB.
I tested every conceivable combination of UEFI/BIOS settings. Enabled/disabled Legacy USB support, switched between Legacy & UEFI and UEFI-only modes, tried enabling only the UEFI USB drive boot option and then only the non-UEFI USB option, changed the boot device priority a zillion times. Nothing works.
There's strange behavior besides.
Sometimes the MSI UEFI/BIOS detects the USB type/name, sometimes it doesn't. Even with the drive in the same slot with no settings changed, there's an even chance that the BIOS will or won't recognize the drive. It does this with both USB flash drives I've tested.
Sometimes clicking "Save Settings and Reboot" doesn't reboot, and I have to use the reset switch.
Out of probably 75-100 restarts, it has only ATTEMPTED to boot from USB 3 times. Twice I got error messages. "B1InitializeLibrary failed 0xc000000bb". "Reboot or select proper boot device, or insert media in boot device and press a key." Once it just froze on a black screen.
And now the system doesn't even TRY to boot. It goes directly to the BIOS every time, without any keys pressed.
I suspect the MSI B450 Tomahawk is at fault because of its inconsistent behavior. At this point, even if I get Windows installed, I don't know if I can trust my system to this motherboard.
Suggestions? I'd dearly appreciate any help.
