http://www.sevenforums.com/tutorials/219533-troubleshooting-windows-7-failure-boot.html may help to an extent. There are steps there that will at least allow you to backup your data.


Also, try clearing the BIOS software/hardware connections and clearing temporary memory of corruption prior to installing:

1. Shut down and turn off the computer.
2. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
3. "Remove the computer from any port replicator or docking station, disconnect
   cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices." (Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English))
4. Hold down the power button for 30 seconds. This closes the circuit and ensures all
   power from components is drained to clear the software connections between the BIOS
   and hardware and clear any corruption in the temporary memory.
5. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall. Do not reconnect any unnecessary peripherals; monitor, keyboard,
   and mouse should suffice and be the only peripherals reconnected.
6. Turn it on to reinitialize the software connections between the BIOS and hardware

I would suggest only installing with your licensed version of Windows 7 and not with Ultimate.
