Say operating system not found

No OS. Reinsall the Winows Operating System.

Define "normal", does it loads your windows desktop with all icons, does it loads windows, if not you might need to reinstall the Operating System. You can find a nice tutorial here http://adf.ly/ImuHt

The hard drive has issues, or the window files are corrupt. I suggest a computer repair store to retrieve files and test hardware.

well try finding someone who repairs coumpters from their home it is alot cheaper. explain your problem they should tell you weather they can fix it

I was never put my file data at system disk. It's mean I always have two partition drive on my computer. So when the system crashes and can't repair, I can free to re-install the system without affecting my data. Base on my experience there is nothing to do than re-install your system. Backup your data first if its placed on system disk with Live operating system that you can found on internet such as SLAX Linux.

If you have the original recovery disc, do a fresh re-install of your operational system, this will completely erase your hard drive including all the files.

If possible try changing your cd rom or dvd rom for cd use check it is recognised in bios and change bios to boot from it,if you still get the black screen with flashing cursor ,could be os is missing due to hdd failure

This sounds like you have no operating system on your laptop. I bet someway, just as I did before, you have lost your operating system, and it needs to be reinstalled on your computer.

try to reload the operating system
