Re: dell latitude d510 cannot recognise harddrive
Doesn't sound good. A bad cmos battery can cause symptoms like this (small battery inside the computer to run the clock when it is off).
Although I am afraid it is probably more like the BIOS is corrupt. Which is what is called in a bricked state. You may find info on the Internet for tricks for trying to get it unbricked, but they don't always work. :(
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Yes, you either have some corrupt or missing boot or system files. Run the Check Disk Utility.
To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r Check disk will run well over an hour or two and you will notice thepercentages going from high to low, this is normal. Let it run tocompletion. Then reboot machine.
If check disk fails to solve your problem you might have to reinstall windows.Try doing a Repair Install that way you don't loose your data, documents,music, pictures, videos or programs.
In windows xp you get to the dos command prompt by selecting R for repair whenthe options appear.
In Vista and Windows 7 you want to get to the recoveryconsole and look down at the bottom of the window for the Dos Command.
You can get it from unlockbiosrecovery I use them when I need a laptop bios password cleared as I repair laptops and see this often. $20 and they guarantee it to work or you money back. Worked every time for me.
Check the lights on the power LED. If it is steady green and there is no display then your computer is clearing POST, and there might be a Video card or screen backlight issue.
However, if the light is blinking green or amber etc then its a post issue and you will need to get the computer checked by a hardware technician.
If this was helpful, then kindly rate me.
unmountable boot volume means that either your system is corrupted, your boot.ini is damaged, or your boot sector is corrupt. Try this:
"You can boot to the XP cd and when you see the Welcome to setup press the letter R You will get a dos prompt Then type "chkdsk /p" without the quotes and hit enter When that is done type "fixboot" and hit enter "Y" and enter at the prompt Then type "exit" and hit enter The system will now reboot into Windows"
