Re: hard disk wont start
Probably hardrive is defective. However you can enter the BIOS and revert the settings to default and test again. Also perform full power cycle. If issue persists I recommend you to replace/service your HDD.

After much time and frustration you will end up reloading the operating system, the reason is it is corrupted, why this happens is not always the same, but the fresh copy of the operating system is the cure. You will need the recovery disks do this, you were either given them with the system or you were prompted to make them when the computer was new. If you don't have the recovery disk set then call the parts dept of the computer maker for ordering instructions, they run about $25
Do you know how to bring up the bios ? (try pressing del or f10, f12, f2 while the dell logo is showing at startup) usually one of these will open the bios. Now look for your "primary master" click on it and then click on populate when the option becomes available. As long as the bios can "see" your hard drive it is still good.
from here you have 2 options. the first is to pull out the hard drive and put it into a usb enclosure and reinstall your OS and software onto a new hard drive, while retaining access to your files and such on the external drive. the second is to use the recovery tools on the OS install disk to try and repair the MBR (master boot record).
Note: Format would delete all of the data(like pictures, documents.) from the computer.
Make sure, you back up all of your important data before formating the hard drive.
1. Insert operating system disk.
2. Shut down and restart the computer.As soon as, you restart the computer, start tapping 'Spacebar' key. Now, this would start loading from disk.
3.Hit F8 to accept the license agreement.
5. Enter Enter again and follow the on screen instruction and this would format your hard drive.
Note: once you format the hard drive, you would need to install drivers as well. Make sure you have the drivers and utilities disk as well.
1st chose harddisk and hit enter
2nd chose the boot order put the 1st device harddisk, if that will not solve your problem start the laptop in SAFE MODE and restore at a previos stage wen was working ok .
to start in SAFE MODE press F8 at the boot time.and chose SAFE MODE with windows.
Generally the bios setting will be set to check the primary Hard disk for the Operating system and then move to the CD/DVD drive . It looks like your system is not finding the hard disk. Thats why its moving on the CD drive and trying to read it.
Possible issues :
1) Hard Drive crash
Solution : Nothing much. You need to replace the hard drive and reinstall the OS.
2) Hard Drive connection issue.
Solution : Open the chasi and try to figure out if the hard disc is properly connected.
3) Corrupted OS or boot file
Solution : Try to repair the OS use the OS cd and run the repair option.
4) Bios setting to treat CD drive as the primary media.
Solution : Use the F10 option in the Bios to change the primary Media.
What you,ll need is a system restore CD.
Usually supplied with the Computer/Laptop.
Your only other option, is to enter the systems BIOS Setup if possible, and instruct the the computer, to first boot cd/dvd rom drive, with your windows or operating system cd in, and carry out a new installation. this could be a missing file/driver issue. or failed RAM ( Memory ) Which can only be determined by listening for Beeps at system startup.
Have you installed any new hardware or loaded any new software lately? If not you might have some corrupt files. Reboot the laptop in safe mode. Just hit F8 a few times. It should give you a menu. Arrow to safe mode and hit enter. After it finishes booting to safe mode, do a system restore. Click Start>click Start>Accessories>System Tools>System Restore. Choose a date before a couple of days before you noticed anything happening. Restore will take a few minutes. When it's restored and booted, I want you to do one more thing. Click on start>run>type in cmd and hit ok. This will take you to your command prompt. Type chkdsk /f It will tell you it can't run it right now do wan't to run it the next time you start up? say yes. Close the window. Restart the computer and the check disk program will run and fix your errors.
If this has fixed your problem please rate it as fixed. If nit, just add a comment add I'll be happy to help you out more. Thanks.
Every laptop is accompanied by a preinstalled vesion of Windows, on the same hard disk in a hidden space. So if you get a prompt to restore your laptop to a previous state at the beginning of system startup, press the relevant key.
If windows xp is your choice. and want to install it you may need follow the installation instruction from your system manufacturer.
When the system starts up some information is displayed on the screen, like this: " Press F1 to enter setup"
If you press the relevant key and enter the BIOS setup you can find the CPU temperature settings, shutdown temperature etc...
This may not be you case. So I suggest you to get support from a qulified technician. Your system hardware should have some problem. (motherboard or hard disk is more prone to error)
you can also try to find information from your system vendor's manuals and support website.
All the best
