Whie trying the system reset (i.e. wiping out all prigrammes and rebboting afresh) the rebooting stooped after about 93% booting with the message NTLDR Missing . Now the computer does not boot. It does not have a CD drive . HOW to correct thge problem to get the computer booted properly?
USB cd-rom's are pretty inexpensive. Here's a page of examples:

Or you could put a Hirens boot disk on a USB thumb drive and run it. There are articles how to repair that error message. Do a Google search for "NTLDR Missing".

f you get back into Windows again, you can change that "1st Try This" menu by going into Start > Control Panel > PerformanceAndMaintenance/System > Advanced tab > Startup and Recovery section, Settings button > System Startup; then change the "Default Operating System:" to the selection that worked for you, and change the box that says "Time to display list of operating systems" to however many seconds you want (usually 1 second). Click OK twice.

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.

If you don't have documents, pictures,
etc on the hard drive that you need to backup, try running system
recovery by doing the following (not sure if this works on the version
with a solid state drive):
1. Turn on the computer
2. Press and hold Alt + F10
3. Click on Restore System to Factory Default
4. Ensure the netbook is plugged into AC power instead of running off the battery and click OK
* This will return your netbook to the condition it was in from the manufacturer.
