Hi there, got a HP Pavillion 17-e002sg here. It booted into Windows just fine, but only using an external monitor. The laptop screen has vertical lines. The external monitor wont show the bios. Only windows gets shown. As of today, the HDD died and I tried various youtube videos to navigate through the BIOS in blind mode. But to disable Secure Boot, I need to enter a number afterwards it seems...which I cant see. I tried booting various CDs, (Win 8, Win 10, Knoppix etc.) but they all did not boot. I tried to pre-install windows 8/10 to another HDD and boot it from within the laptop. It fails of course. Is there any "cheat" to get an external monitor working before Windows, to view the bios ? Is there any chance someone has a HDD image of this particular laptop ? Would it be possible to flash a already "Secure Boot DIsabled" BIOS via Crysis Recovery ? I already tried "Windows Key + B + Power On"..which should re-flash the last bios...but I only get a blinking CapsLock...which, according to google results, means a defective CPU or Mainboard...yet the Laptop booted and worked just fine this morning. Any help is really appreciated.
