No, nothing inserted in any drive. Turned the computer off before bed last night, turned it on this morning - it DID briefly show the startup screen from HP (where I can choose like f9 or f11). Then a black screen with white letters came up - couldn't copy it all down, but: Intel UNDI, PXE-21 (build 083) bunch of stuff about patents Client MAC ADDR 64 31 50 33 2454 GUID... something... ended in DHCP... with a scrolling cursos That was up a few seconds, then there was a fast message about No Boot Filename Received and now the original message I posted about reboot is on the screen.
