can you boot in safe mode
enter into the bios and check if the hard disk is available...
do you have any network cables or usb devices plugged in during boot?
In the set up utility looking at the information page it says none under both IDE0 model name and serial number. I don't get an option to boot in safe mode during the process it just goes to the messages I indicated earlier.
im not sure but i think you may have a partition problem . i am looking for a free partition program to see if thats the problem .
Open the back of your laptop and check your SATA cable hasn't came loose form your hard drive.
I would reseat the hard drive. Pull it out and put it back in, then run diagnostics on the hard drive

Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.

See this for how to make a bootable cd
go to control panel - administrative tools -computer management - disk management

there are your hard drives and the partitions . check if all the partition are healthy and activated .

Since the computer won't boot how may access this?
I suggest that you follow Old Rich's advice.

If the system cant boot ?,how are you going to achieve the above,^ to control panel - administrative tools -computer management - disk management
Stick with Old Rich,you may also want to try this,


This issue is often caused by either an incorrect setting inCMOS Setup or a bad boot device, such as a bad hard disk drive.

Verify your boot options are properly set in CMOS setup. Set the CD or disc drive as your first boot device and then hard drive as the second boot device.
If your CMOS Setup has an option to boot from the LAN disable this option. make sure to save and reboot the computer.
what about safe mode ? can you boot in safe mode ?
So I have done step 1 form old Rich and pulled and reseated the harddrive. It's a Western Digital Blue Scorpio model WE2500BEVT-222CTD. Which diagnostic program do you recommend?
There are several WD listings on the page you linked.
