FDISK is a great old tool. Guaranteed to wipe your drive out with a few clicks on the keyboard. If this was your primary disk you could try using USB booting tools. It sounds like you killed your MBR.

Easy fix if you have two computers. Take HD out and stick in another computer as a secondary HD and see if you can see it.

Deleting the MBR should not effect the BIOS in detecting the hard disk. All the BIOS reads initially is the firmware and some hidden information put there by the manufacturer that Fdisk or any other partitioning software wont touch.

Until the BIOS can detect the hard disk you wont be able to do a thing. I would check that all the cables are sill firmly in place and that you haven't inadvertently changed something in the BIOS setup.

As Stuart has already stated the changes you made can't affect how the BIOS configures your hard drive.

If the computer listed in your specs above the unit in question?

Watch the POST screens at start up to verify the BIOS is properly configuring the hard drive by both the drive model and the FULL drive capacity. What does the following mean? "Its Insyde BIOS Syst".

The BIOS created by Insyde corp. Its getting worst, i even cannot boot with my WinME MS-DOS startup disk. Something must be so wrong with the BIOS or HDD

OK, Insyde corp. appears to be the vendor that assembled your computer.

The screens that display by them are NOT the BIOS screens.

Do you see any screens BEFORE those? If not, then reboot and tap the Del key until the BIOS screens open. Read the prompts on the page to learn how to move around in those screens. You need to first check the drive configuration screen to see if your hard drive is listed there.

Then look for a screen that has a listing for fast boot. Set to disable.

Then look for a screen with any mention of Logos and disable all logos. Save and exit by following the prompts.

Now you should be able to see the actual POST screens. Look for the drives as I described above and post back.

Check the drive cables.

As already mentioned running fdisk won't cause the bios to lose the drive. But then, just typing FDISK and enter at a dos prompt won't affect anything either. It depends on which fdisk option you chose. So which was it?

You're not really green until you're soylent green.
