I've read this problem due to new hardware interferences with desktop computers, all they had to do is change a few pins around on the harddrives.. since this is a laptop, and is quite difficult and dodgy to access the hardware, the only other suggestion is to reinstall windows with a recovery disk, or windows CD-ROM.

Your notebook does not see the proper boot files on your C drive. Many times the boot.ini has been corrupted.
You will need a Windows XP Install CD mounted in the CD Rom. When you boot the system you need to choose the CD as the boot device (if the notebbok does not do it by default) then typr R to enter the recovery console. Once you get the C: prompt you will need to create a new boot.ini file using the bootcfg command. See the following website for details in using the Recovery Console:

I'd like to help you, but it is very difficult to diagnose based on your description. We will need to gather more info as we try a few things.
1. Why are you reinstalling? 2. How old is the system? 3. Try the following & let me know the result: turn system back on. When the normal LED indicators are on, press & hold down the power button for 4+ seconds until everything goes off. 4. If step 3 worked, then turn power on & hit bios setup key (f2?). 5. See if HDD is detected.
