I have this HP dv5 which was working perfectly fine with Windows Vista.
I tried to install Windows 7. During installation, I got the message that Windows would restart (which is pretty normal). My laptop never restarted.
I am now stuck on "hp invent" screen and at the bottom left I see Press Esc key for Startup Menu.
Nothing happens when I press Esc and I remain on the same screen.
What I have done so far:
Removed and reinstalled RAM (3GB)
Tried one RAM stick at a time
Removed battery, kept the power switch pressed for 15 seconds and tried to boot with power (without battery)
Removed RTC battery and kept out for 15 seconds
