hi everyone,

I am having a major problem with my Toshiba laptop, Windows XP home ed. after a few weeks of having an extremely loud fan processor. Now when I turn on the computer, I get a black screen with the message "windows could not start because the following file is missing or corrupt <windowsroot>\system32\ntoskrnl.exe. Please re-install a copy of the above file."

I have the Toshiba Recovery and Applications/Drivers DVD, and changed the BIOS to boot first from the disk. However, this did not work and when I put the comp on, I get a black screen with a blinking white cursor for a few seconds, followed by this message ... "pxe-e61: media test failure, check cable" and "pxe-mof: exiting pxe-rom." It stays on this screen for a few seconds before going back to the original error message ("windows could not start because the following file is missing or corrupt <windowsroot>\system32\ntoskrnl.exe. Please re-install a copy of the above file.")

Whenever I hit any key, the comp reboots and does the same thing over and over. I can't go into safe mode, or do anything really. I am worried that I will lose my files that I have stored on my computer, so any suggestions anyone has would be greatly appreciated.

Thanks in advance,
MR

The loud fan noise on the processor cooler is extremely dangerous. If that fan fails it can destroy your processor in an instant!

As far as the missing or corrupt file, NTOSKRNL.EXE
see if any of the information on the following link helps:

thanks so much for your reply. Unfortunately, the information provided in that link works only when the disk is accessible.

I am assuming that you do not have a Windows XP installation cd (not a restore cd). Is that correct?

If so, what I suggest you do is get an adapter so you can hook up the laptop's hard drive as a slave in another computer, and then backup the data that is on it.

Then replace the hard drive in the laptop, reset the boot order in the bios, and use the Toshiba Recovery cd to reset the computer back to "new" condition. If it has a repair option try that first.

My Toshiba came with a Windows CD and a driver CD. It will not boot from the driver CD - but the Windows CD worked flawlessly for me the last time that I used it.

Hi Enthusiast,

I'm hoping you can give me more information on hooking my computer up to another computer, as I have access to another Windows XP computer this weekend. What kind of adaptor do I need? And what do I do once I have them connected?

I tried copying ntoskrnl.exe, boot.ini, NTdetect, and NTLDR to disk from another computer, as per recommendation from a friend, then put the disk in my laptop, hoping to replace the corrupt files. However, since I still get the error message when I put the computer on, I am unsure as how to proceed. I reset the BIOS to set to boot from CD first and tried disabling the LAN, but upon reboot, it always goes to the error message screen.

Again, any suggestions are welcome. Thanks!

Make sure the problem isn't a loose cable to the hard drive before pulling the hard drive and using an adapter. Also use a can of compressed air to blow the dust out of the air intake port. Many laptop problems are due to loose cables, plugged intake ports and fans.
