Have you tried to unplug, remove battery, plug in, reboot and select the System Restore/Recovery software? You didn't post the HP Model or the OS you are using?

SOURCE: boot safe mode
to boot safe mode,
1. tap the f8 button while your computer boots...before your windows starts load and just after you press the power button.
2. a screen will appear it will give you the option to boot in safe mode, select it

Did you attempt to load recovery/factory image from hidden partition and if so did you follow User Manual or Guide re instruvtions? if so there should have been no problems. I would try again though do it slowly and carefully when choosing Options so that you don't change Partitions where the Default Software is.
Was it Alt and F10 buttons when powering up from a Shutdown, i.e Cold Boot?

You need to fix the boot manager problem first by connecting an external monitor to the laptop so you can see and do a system repair.
As for the backlight problem :-
You could have a faulty CCFL lamp or inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Tips for a great answer:
Restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer
If done properly the user should get to a screen similar to the below screen.
Select the option for Safe mode command prompt only
Windows Advanced Options Menu
Please select an option:
Safe Mode with Networking
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Start Windows Normally
Return to OS Choices Menu
Use the up and down arrow keys to move the highlight to your choice.
Select safe mode with command prompt then type in chkdsk/f/r which will scan for and and attempt repair of bad files and bad sectors on hard drive
You should have no input while chkdsk utility is in progress any input might further damage your computer also
Use the System File Checker tool (SFC.exe) to determine which file is causing the issue and then replace the file.
Type the following command and then press ENTER: sfc /scannow The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

Turn off the computer, then hit the power button to turn it
back on and immediately start hitting the F8 key repeatedly until you see SAFE
MODE. Take the Safe Mode option and let it boot up. Safe Mode will look
different to you, the screen will be darker and the icons bigger, this is
normal. If it boots up ok, then do a restart into your normal windows mode.
Try running the check disk utility.
To run the check disk utility you will need a repair disc or
a operating system disc. Put the disc in the cd drive and boot from
it. You want to get to the Dos Command Prompt (Black screen with white
letters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice the percentages going from high to low, this is normal. Let it run to completion. Then reboot machine.
If check disk fails to solve your problem you might have to reinstall windows. Try doing a Repair Install that way you don't loose your data, documents, music, pictures, videos or programs.
In windows xp you get to the dos command prompt by selecting R for repair when the options appear.
In Vista and Windows 7 you want to get to the recovery console and look down at the bottom of the window for the Dos Command.
