Short story: BIOS says boot order is network > USB > SSD, but won't boot from any USB stick.
Tried using Windows recovery options and choosing "use USB", and also the volume down + power to boot.
Tried switching BIOS to boot only from SSD, saving/rebooting, then back to "USB", and save/reboot.
Story:
So I have a Surface Pro 3 and installed the Windows 10 Technical Preview. Wanted to go back to Windows 8.1 and start clean (all my files are in OneDrive or another PC, so this tablet could be wiped clean). I tried my Recovery Stick and it wouldn't boot from it, so I downloaded Windows 8.1 Pro from MSDN and ran setup.exe. I thought I would use it to create yet another USB install stick, but it actually let me choose to "keep nothing" and install it without creating secondary media. It's running perfectly fine, but I still can't boot from USB.
I can read/write files to any USB drive just fine.
I noticed this when I tried to create a Windows To Go drive, I could create it but not boot from it. Now I'm trying to use it to launch Windows 10 Setup and install it into another partition (I like Windows 8.1 too much to go solo 10 even on this secondary device). But nothing so far has let it boot from USB and I am out of ideas.
