If this is a XP professional OS then you should be seeing XP Recovery Console in the options.
If not and it is a XP home then repair may be impossible without a XP install CD.

Which is it?

find restore disk

The above link is a place you can purchase restore disk. You search by name and model. I used it once to help someone else and I believe I paid around $25.

The computer manufacturer is where I would look first.

If you start in safe mode it lists about 15 files the last one being multi(0)rdisk(0)partition(1)\windows\system32\drivers\isapmp.sys....

G'day once again!

What happens when attempting to load Windows in Safe Mode?
  • Does it simply stop at the above mentioned screen showing the last driver loaded?
    How long have you waited? Give it a good amount of time ... and hour or two would be appropriate.
  • Or does it progress to some other screen and then hang?
  • Or does it re-start?
Please get me the boot log. You know the drill:

Test the hard drive. You know the drill:

Good result on the hard drive.

Let me test my instructions for searching for ntbtlog.txt ... in case I got it wrong?

So, you have been looking at the screen showing the last driver loaded for 45 minutes ... so far?

Having a look at my own ntbtlog.txt, I note that isapnp.sys is loaded very early (10th down the list).

Note: that is isapnp.sys and not as you have typed it in your original post (PLEASE CONFIRM FOR ME!)

So it would seem that something is going wrong very early in the boot process of loading the first lot of drivers.

ntbtlog.txt is the correct spelling of the text file that you should be looking for, and you should be looking inside the Windows directory (folder).
  • You would click on Windows in the left-pane to highlight it (there is no need to expand it by clicking on the little arrow beside Windows).
  • In the right-pane, would be displayed the contents of the Windows folder, and it is here that you would look for the text file ntbtlog.txt.
Edit: I'll think about this some more after a nap.

Can't read anything on that .bmp image ... too blurry. Use .jpg or .png format when attaching images (not as large in file size). I'll take your word for it, that ntbtlog.txt is nowhere to be found.

Not to worry about the missing hard disk drive: Windows is like that. Let's try other ways to get around this little annoyance ...

Do you perchance have a Vista or Windows7 (or XP 64 bit for that matter) installation disk from which we could boot and attempt to run chkdsk /r? (The version of chkdsk is better than the standard XP version.)

Another alternative that sometimes works when the standard XP Recovery Console chkdsk will not ...

Please try the following ...

Let's use a FreeDOS image for CD that contains a few tools (compiled & hosted by noahdfear).

The first step is carried out using a working computer.
:step1: Download NTBR_CD.exe and create a bootable CD:
  • Save the file to your Desktop and double-click it. This will create a folder named NTBR_CD.
  • Open the folder and locate BurnItCD: Launch it by double-clicking it.
  • When BurnCDCC opens, click Start: The CD tray will open.
  • Insert a blank CD and click OK.
    The tray will close, burn the image and then eject the disk.

:step2: Run chkdsk on the problematic computer.
  • Boot the affected computer with the new CD.
  • Once presented with the boot screen press <ENTER> to boot from the CD.
    After a warning screen there is a keyboard language options screen.
  • Press <ENTER> to leave it at EN-US.
    You should now be at the Tool options screen.
  • Type 5 and press <ENTER> to choose the command prompt.
    You will see an X:\> prompt, where X: is the ramdrive (temporary drive space in memory).
  • At the command prompt type the following bolded command:

    tools\ntfs4dos\chkdsk
  • and press <ENTER>.
    You will be prompted (in ?Dutch) to press <ENTER>.
  • Press <ENTER> to start the check disk utility.
    Check Disk will check all attached drives and attempt to correct any errors.
    Please make a note of any errors found or corrections made.
  • When it completes type menu and press <ENTER> to return to the tools menu.
  • Type 6 to select Quit, and press <ENTER>.
  • Press <Ctrl+Alt+Del> to restart, and remove the CD.
  • Allow the computer to attempt booting normally and let me know the outcome.
Please let me know if chkdsk reports any errors or corrections made, or if it completes without incident.
***(With thanks to noahdfear for the above tool and instructions.)

windows made corrections...

Run NTFS4DOS chkdsk again please. Then test starting normally.
  • Test starting in Safe Mode also:
  • Do you still get exactly the same drivers loading on-screen, and ending with isapnp.sys?
If necessary try chkdsk /r from the Recovery Console again. What happens? Still "no hard disk drive"?

When attempting to start the computer normally, please describe exactly what you see on-screen, and for how long ... until you get to the ? blank black screen. How long have you let it sit and wait for something to happen???? Try leaving it for an hour or so.
