Surface book keeps trying to boot from USB

[Christopher Lindsay]

I disabled USB boot from the bios but it keeps trying to boot from USB when I have my external hard drive plugged in. This very annoying. Anybody else have this problem?

I have not had that issue. I keep my external plugged in as well.

Does your external drive have an OS partition on it? The windows bootloader may be looking for bootable drives, thus presenting you with a choice on boot if your drive is indeed bootable.

No. Sometimes I don't even have an external hard drive plugged in it. Just a USB hub and it will try to boot from USB anyway. It gets stuck and just stays on the surface screen until I unplug whatever is in the USB slot.

Interesting... I wonder what MS support would have to say about this. Clearly something is wrong here... ? (then again, this device seems quirky as heck and almost nothing surprises me at this point).
