Have you seen this screen
- Figure 1: Example of a hard drive listed in the BIOS
and if so which drives are listed.ON THAT screen - as asked by my colleague. I know you say only the WD but were you on this screen. IF SO which devices were detected, as if it was ONLY the WD and your CD drive, then your system drive from which you boot is indeed not shown.
see AGAIN please fhe link provided from HP for YOUR computer model and follow the directions for the DRIVE is listed or the DRIVE is NOT listed.
Then if it is NOT listed - follow the instructions for resetting the BIOS to default.
F5 and F10
I presume for your last you have done that, but that step was AFTER the confirmation of it NOT being seen in the BIOS
The reset referred to by me
please follow the procedure firstly for a reset and then for the bios check to see if the HDD is detected.
AND on the HP Compaq link was the reset
- Turn off the computer and unplug the power cord from the power outlet.
- Reset the power: with the power cord unplugged, press and hold the power button on the front of the computer for 5 seconds.
- Plug the power cord into the power outlet.
- Press the power button to turn on the computer and note what happens.
after disconnecting all peripheral devices.,. as on the link.
I apologise you have become confused, but can you imagine the amount of typing we would have to do if all advice was typed out rather than sent as links
