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 just disconnecting the keyboard from the computer.

Miscellaneous corruption

Before trying any of the below recommendations it's recommend that you load the last known good configuration.

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 its drive and partition is properly configured in the [boot loader] and [operating systems] section.

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.

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

Check the hard disk drive for any errors by running the chkdsk program. 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 reinstall Windows.

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

Tip

If you get message: " boot disk failure" then follow this tip


1)If any cd or dvd is there in the cd or dvd drive remove them first then try booting
if problem persists then
2)check the boot device priority in the BIOS menu,change the boot device priority if required(change to 1 st boot device floppy, 2nd harddisk drive,3 rd to cdrom drive something like this)
to go to bios setup press del or f2(it depends if del key doesnt brings you the bios utility then press f2) at time when you switch on the pc ie at the time of booting the pc ,
if problem persists then
3)check whether the harddisk is detected or not in the bios setup
if it is not detected then just open the CPU & check the bus & power supply cable connected to the harddisk remove them & reinsert them ...
if required then replace with the new ones ....
if the problem persists then
4)the operating system might have got corrupted just reinstall ....
if problem persists then
5)the harddisk partitions might have got corrupted or crashed ,just try partitioning them again and by installing the operating system.

Computer will not boot up


This is because of either the system has shutdown while it was processing a windows file. sometimes repairing the OS or running a CHKDSK /R in the recovery console will fix this problem. if that doesnt help i recommend you change your HDD

Ntldr is missing, press ctrl,alt and del to restart


the ntldr.sys file is used to boot your winxp, this should have got corrupted, or your boot sector in the harddisk should have got corrupted.

what file system was used on your harddisk ( Fat32 or NTFS)

if it is Fat32 then you can try this. boot your system with win98 boot cd or floppy. after booting insert your windows xp cd in the cd drive copy the file ntldr.sys from the i386 folder to the os root dir(usually the c:) you will receive a overwrite message. do the over writing. thats all.
now restart your system normally (harddisk). it should be fine.

if the file system is NTFS, i am sorry to say, if you dont know the admin pass, you will have to repair the installation with the winxp cd,

for this boot your system with the winxp cd, on the first screen, press enter( for a fresh installation), then press F8, now you will be notified that there is already a window installation, on this screen press 'R' to repair the installation. follow the online screen.

Actually this is a nothing but just a reinstall of the OS. you may have to reinstall most of the os updates. and a few softwares also.

Hope this helps you.

The quick restore dosen`t work


What operating system you are using before installing windows xp. If it is windows 98, Your restore cd will restore windows 98. if you want to restore to factory settings pls boot from the restore cd and format the harddisk. Becareful, this will erase your entire data on the harddisk which cannot be recover. If you are using licenced (not pirated) windows xp boot from it and reinstall windows xp so that you can run the os smoothly. But in either case becarefull when you are formating, it will destroy entire data and you may endup in soup. feel free to revert back for further quiries
