Hello , on this system I'd manage to install Windows 7 64bit Home Premium edition. All fine for the end with all drivers installed on support section.
After some minutes HP Assistant give an update for the BIOS component at the latest version. I accepted and installed the latest version.
The behaviour was a little strange because it installed the update but doesn't call for a reboot. I rebooted the system but after that the machine doesn't boot anymore it has black screen ,the fan accelerate after one minute and i saw that it leave about 5 minutes it lit the lcd screen. Sometimes it beep once and restart itself but is eratically.
I'd manage to install the 3 in 1 diagnostic tool on usb thumb and booted that , it enter in UEFI diagnostic tool but it ask for CSO number and Agent ID , I introduced blank values for both and i saw that It doesn't show the firmware management.
Second method what I tried was to build a usb thumb with upgrade bios and started the system with key combination win+B
