Laptop not going beyond loading windows.

I have already tried system restore and startup repair countless number of times but to no avail
No i have no important files so i did not feel the need to backup my files.

the setups which i needed are stored in D drive..

How did you run Startup Repair and Restore? From the booted DVD or Repair CD?

What are setups? Downloads? Having them on D if it is on the same HD is NOT backup. To try to overcome install problems you need to wipe your HD so back up anything from D now to another HD, USB external HD or flashs stick, or DVD using Copy & Paste - in Windows Recovery Console

If you have not tried to reinstall yet then boot the installer, use Custom install Drive Options shown in Steps 6/7 of Clean Install Windows 7 to delete all but the D partition where your data is stored, then create a new partition in the deleted partition space, format it, highlight it to Install on it.

While it installs read over the steps for Clean Reinstall - Factory OEM Windows 7 so you know how to proceed once Win7 is loaded, particularly with drivers - have your ethernet cable plugged in during install to get online fastest to get all rounds of Important and Optional Updates including drivers.

As long as you don't touch the D partition your data should be safe. But its safest to back up any data you need at all times since the HD could always fail.

i just booted my laptop thru safe mode with netwrking.
this was the first time i reached beyond loading point..
it said i need to restart my lappy to make changes n wn i dd i can now access windows normally !!
WTF is happening !! n know the problem will resurface again

it itself gave me the option either to start windows normally or run startup repair..
i dont need to back up anything..
wn u go for system restore ur entire data installed after the restore point is wiped out.
so in order to avoid the hassle of downloading the setups of the softwares, i copied their setup file in D drive cz D drive is not affected by restore process..

I specfically said to run Startup Repair and System Restore from System Recovery Options
on booted installer or Repair CD, not the auto-start one which you ran.

Data is not affected by System Restore. But your your data should always be backed up for the reasons I've mentioned.

In your case I would see if the vastly superior Clean Reinstall - Factory OEM Windows 7 makes the difference for your Lenovo. But a lot depends upon whether you follow the steps closely. You'll get and keep a perfect install as long as you stick with the tools and methods given.

I saw the screen shots of the process through which you restore through system recovery options and it is not different from the autostart option in any way..

But i am going to follow the clean reinstall thing and let you know :)..
thanks for all the help though :)

The autostart Repairs depend upon System files which may be infected or corrupted.

i went to download the iso file of windows 7 home basic 64 bit but they have iso files for starter, home premium and ultimate..

what should i do now ?

If Basic is the licensed OS on your COA sticker, then download the Home Premium ISO, run the eicfg removal tool on the downloaded ISO, burn to DVD or write to flash stick using Windows 7 USB-DVD Download Tool,

Boot to choose your licensed version for install.
