Envy ultrabook 4 does not boot to windows

[maxium_burn]

I have an ultrabook ENVY 4 that boots to blue error screen which I a have enclosed.  I recently installed windows 10 from windows 8..      Windows 10 worked  and had been installed for 3 week.   The problem started after battery died and I turned on laptop.  The start up screen gave choice to boot to windows or HP operating system ( This is some default menu I recognized since working with the laptop even with Window 8 installed.   I inadvertenly selected HP and thats when I got the error boot see  images below.  I tried several fixes:

    I tried to boot from a USB that had window 10 no go... I pressed F keys to get to the HP recovery menu which only enabled me to check Hard drive and computer chip integrity which were all ok.  But I think a repair menu did not work.   I tried to boot from BIOS which did not find something to boot from.  The crazy thing the bar code scan goes pulls up a windows site menu which does not address the issue.   I am guessing that a hard reboot is needed  resetting CMOS but I do not have a removable battery and a 15 second push on power button does not work.
