[21:51] <dckc> Hi. This HP Envy says "selected boot image did not authenticate" when I try to boot from USB stick. I have a working Ubuntu desktop (where this IRC client is running). Clues?
[21:51] <dckc> Most clues I find are about upgrading the bios -- how do I do that when the HP Envy won't boot?
[21:52] <dckc> When I let it try to boot windows, it goes into recovery / repair but then says "recovery failed" (roughly)
[21:52] <dckc> It looks like I need to make a UEFI boot USB stick. Clues for doing this seem pretty obscure.
[22:00] <dckc> ooh! I think I got it...
