✔ Best Answer
Did this just happen all at once? Did you make changes in the BIOS prior to this issue?

Your computer is trying to boot to a network. This happens when there is no bootable device listed before the network boot.

Your hard drive may have failed. When starting the computer is the hard drive showing up in those screens?

Use another working computer to download and burn to CDR a utility called Seatools for DOS. This can test your hard drive to determine its health. Get Seatools for DOS from the link below. You boot directly to that CDR, so be sure you have the CD drive set asthe first device.

If your hard drive is OK then your installed operating system (Windows) is not working correctly and may need to be repaired or re-installed.

Hi i have done the seatools dos and the laptop comes up with no hard drives found if you believe this to be incorrect,check cables,drive power connection and jumper settings and then try again i will let you know once i have took it out and checked it again
If it doesnt work after that does it mean my harddrive is dead ????
Thanks for your help Othehill

Try to set BIOS to factory default settings and reboot the Laptop.

Wouldn't hurt to try the default BIOS settings but it sure sounds like the drive has died.

Be aware that the hard drive in a laptop usually has some sort of carrier that you must reuse. Don't throw the old drive away.

Also, the old hard drive MAY still be under warranty. What is the model of the drive and how old is the laptop.

Have you tried to boot from CD/DVD, just to check, whether CD/DVD is working?

If booting from CD/DVD will also fail, it's most likely the controller, implemented to the mainboard, that has died.
And that's the worst case!!!

Agree, if the hard drive didn't work in another laptop, it might have died.
But, is the hard drive listed in the BIOS.
Maybe you only lost all the data and maybe the partitions on the drive, which will end up in the same result.

If I were you, I would download e.g. BartPE, burn it to CD, boot the computer with it and check, whether there is any partition on your hard drive.
If it's not, your hard drive might work but all the data and partitions on it where lost.
In that case, you have to install your operating system from scratch.
During intallation, the e.g. Windows XP or Windows 7 will find the hard drive and will repartition it, so that the operating system can be installed to it.

I used a program called seatools for dos that didnt find the hard drive at all but when i ran it on the desktop it found all three i have tryed reinstalling windows 7 and it just sits onthe set up page and is constantly working not sure how long to leave it so i usually shut it down after a while might try to leave it for an hour in the morning and see if anything happens dont think ti can hurt

In that case it might be best, to use a drive fitness test for your hard drive.
E.g.: If your hard drive is a Toshiba drive, you have to use drive fitness test for Toshiba drives.
This tool will tell you, whether there is a real problem with the hard drive.

Obviously I was missing some posts above. You already used the correct tools. So while SeaTools did not find any hard drive, it's gone (dead).
Time for a new one, I guess.

If the hard drive is making click sound while trying to install windows, it tries to read track zero of the hard drive. If this track zero is corrupt, the hard drive has died.

Try booting off a Linux Live CD & see if you can access your files. If you can, transfer them to a USB HDD or flash drive.

Toshiba doesn't have a fitness test of their own. Seatools for DOS supposedly works with any hard drive.

If jim burned Seatools to a CDR then he must have used the optical drive to run it.

It wouldn't hurt to try accessing the hard drive with a Linux distro or with Barts. That said, if Seatools can't access the drive then something more is wrong than just a lost OS.
