I have checked the follwing links -
I have uploaded my DxDiag output but if you are interested only on the keyboard details -
+ Standard PS/2 Keyboard
| Matching Device ID: *PNP0303
| Service: i8042prt

I have also visited the local Lenovo service center but they were not able to properly diagonise the issue. Their only solution was to change the keyboard and since this was an international product they said that they couldn't find any replacement parts. I didn't expect such a irresponsible reply.
In case you need more details, feel free to comment .

I'm curious what will happen when you set back the original Fn & left-Ctrl key mapping on your system w/ Windows?
If you will see nothing improved, I suspect keyboard H/W issue.

Sorry for the late reply. I tried changing the setting back. But now all the keys have been remapped. I dont think its just a H/W issue. I suspect some S/W problems also. The keyboard (except the fn key) works fine once it enters the OS . But during GRUB and Windows login screen it misbehaves.
