Faulty HP Laptop

Note: The following notes assume an XP environment. The
steps are similar for both 2000 and 2003 environments, but I did not
take the time to investigate if there are any differences here.


Boot to the recovery console.

Turn on the computer, pop in the Windows XP CD.


Reboot the computer. If the Windows XP CD does not boot up, then
reboot, go into the BIOS and configure the "boot order" to boot from CD
first. Lather, rinse, repeat.


Select R for Recovery.

After getting to the Recovery Console prompt, make certain that you are in the C:\Windows path for XP (assuming that XP is on C:, that Windows was installed into the \Windows directory, and that your hard disk is readable).


Change to your CD drive - by typing "D:", "E:" or "F:" etc. -- this varies per system but is most often:

D:

Change to i386 path by typing:

cd i386

Copy necessary files to root path (C: in this case) of winxp installation by typing:

copy ntldr C:
copy ntdetect.com C:

Change back to your windows path:

C:
cd windows

Attempt to fix the boot record:

fixboot c:

Try restarting machine - if still nothing - go back into recovery console by booting from cd Then run:

fixmbr c:

If it does work but you are getting an annoying boot.ini message
everytime you restart your PC now go back into recovery console as
above and run:

bootcfg /?

Reference the below articles for more information on bootcfg. Be certain to select c:\windows as the boot installation.

Cause:



1. Keyboard issue

2. Miscellaneous corruption

3. Corrupt boot.ini file.

4. Missing boot.ini file.

5. Missing or corrupt ntoskrnl.exe file.

6. Windows NT installed on a partition bigger then 7.8GB

7. Corrupted hard disk drive or severely corrupted Windows.



Solution:

Keyboard issue


This issue has also been known to be caused by a short in the
ground wire in the keyboard cable. Make sure this is not the cause of
your error by replacing the keyboard with a different keyboard or
simply just disconnecting the keyboard from the computer.



Miscellaneous corruption


Before trying any of the below recommendations it's recommend that
you attempt to load the last known good configuration. Additional
information about doing this can be found on document CH000626.



Corrupt boot.ini file


This issue is often caused when the boot.ini is missing or
improperly configured. This issue often arises after a user has
recently added or removed an operating system on the computer or added
or removed hard disk drives in the computer.


Make sure the line pointing to the operating system and it's drive
and partition is properly configured in the [boot loader] and
[operating systems] section. Additional information about boot.ini can
be found on document CH000492.



Missing boot.ini file



Microsoft Windows XP users:


If the boot.ini is severely corrupted or missing a user running
Microsoft Windows XP can rebuild the boot.ini to resolve this issue.
Additional information about rebuilding the boot.ini can be found on
document CH000648.



Microsoft Windows NT and Windows 2000 users:


To restore the original boot.ini file in Microsoft Windows NT or
Windows 2000 you will need an ERD and follow the below steps. If you do
not have an ERD you will be unable to follow these steps.



1. Boot the computer with your Windows NT three setup diskettes or the Windows 2000 setup disc.

2. In the setup menu, type R to start the repair.

3. When prompted for the ERD diskette insert the diskette and inspect the startup environment.



Missing or corrupt ntoskrnl.exe file


If the ntoskrnl.exe file is corrupt or missing this can also
generate the error. To restore this file follow the below steps.


1. Insert the Microsoft Windows XP CD. Note: If you have a
recovery CD or a restore CD and not a Microsoft Windows XP CD it is
likely the below steps will not resolve your issue.

2. Reboot the computer, as the computer is starting you should see a
message to press any key to boot from the CD. When you see this message
press any key.

3. In the Microsoft Windows XP setup menu press the R key to enter the recovery console.

4. Select the operating system you wish to fix, and then enter the administrator password.

5. Type expand d:\i386\ntoskrnl.ex_ c:\windows\system32

6. You will then be prompted if you wish to overwrite the file type Y and press enter to overwrite the file.

7. Type exit to reboot the computer.



Windows NT installed on a partition bigger then 7.8GB


If you are running Microsoft windows NT 4.0 on a partition larger
than 7.8GB this issue can occur if the boot files are located outside
this limitation. When this error occurs your computer will have the
error message as shown below.



OS Loader v4.01

Disk I/O error status=00000001

Windows NT could not start because the below file is missing or corrupt: winnt\system32\Ntoskrnl.exe

Please reinstall a copy of the above file.


If your system partition is larger than 7.8GB you will need to
delete the partition and recreate the partition to 7.8GB or less.
Additional information about this issue can be found on Microsoft KB
Q224526.



Corrupted hard disk drive or severely corrupted Windows



Attempt to check the hard disk drive for any errors by running the chkdsk error. To do this follow the below steps.


1. Insert the Microsoft Windows XP CD. Note: If you have a
recovery CD or a restore CD and not a Microsoft Windows XP CD it is
likely the below steps will not resolve your issue.

2. Reboot the computer, as the computer is starting you should see a
message to press any key to boot from the CD. When you see this message
press any key.

3. In the Microsoft Windows XP setup menu press the R key to enter the recovery console.

4. Select the operating system you wish to fix, and then enter the administrator password.

5. Once at the recovery console type chkdsk /r

6. Once completed type exit and see if issue is resolved.


If after trying all of the above steps you are still encountering
the same issue it's likely that Windows is severely corrupted and it is
recommended you attempt to reinstall Windows. Additional information
about erasing the computer and starting over can be found on document
CH000186.



Finally, if during the Windows installation you encounter errors it's likely that your hard disk drive is bad.
