After windows 7 restore, no usb storage devices were available. A recovery suggestion said disconnect power and all devices and remove battery for 20 minutes.
When I come back up I get HP BIOS logo showing v02.99 version and "Press any key for Option ROM Messages" and "Press the ESC key for Startup Menu".
It goes no further without action (key strokes).
Pressing ESC brings screen with title "Startup" in lower right with no screen content. Press PF10 brings screen with title "Setup" in lower right with no screen content. Press CNTL+P brings screen with title "MEBx setup" in lower right with no other screen content. pressing 'any key' leaves screen blank.
Disconnecting HDD or leaving bootable USB stick in and powering on gives same symptoms. All solutions I find involve using content from these menu's where I can't get more than title.
