Get the 98 start up floppy and stick it in the a:/

Copy command.com, or anything else missing to your c:/ from the floppy. type help/? at the c:/ and you should find the proper format for the version of DOS you have.

    you should see the Dos prompt C:\  like that for example type win and press enter if it still persist that the COMMAND.COM is corrupt then you will need to find that command.com and its gotta be the win98 one too.



     



    Gee its been ages since I have used DOS but int eh autoexec.bat you should check to see if thats ok but dont forget to type win if it dont work on the c:\ then type cd space windows enter then type win.   Come back and tell me what happens I am still online and in New Zealand.

    Here is some more info for you will you need to know how to activate this?.



     



     



    Make sure that COMMAND.COM is in the C:\ root directory, or if it somewhere else, that there is a line in AUTOEXEC.BAT that reads "COMSPEC=X:\PATH" where "X:\PATH" is wherever COMMAND.COM resides. Edit the PATH command in your AUTOEXEC.BAT file, if you are trying to run a command in another directory that should be accessible from anywhere.

    Are you able to go back to your friend to get the original 98 disk of him/her because unless you have any know how on DOS that is the way your machine will stay.



     



    What it is saying is that if you change directory to C:\Windows you will find COMMAND.COM by typing command or cmd in that directory the Command .commay be ok. if not then to make it go again you need a knew Command.com.



     



    Where you stand now is here  C:\



     



    That means nothing will run while you are there.



     



    Dos was Microsofts first operating system



     



    the autoexec.bat runs the show including Windows 98 if you can obtain the Command.com of your friend and install it all good you will be up an running however Windows 2000 should also install into that laptop and if it is running 64MB of Ram it will also take Winxp.

    By the way if you do a google search for the original 98 disk you will find them free to download but of course thats another research you would need to do.

I cannot boot up my Microsoft Windows 7 due to a corrupt ntfs.sys file. I can access command prompt through computer or cd. Please help!


As you are able to access command prompt, you can run the "System File Checker" tool to repair/ replace the corrupted ntfs.sys file. To do this, follow the instructions below:
1.Restart your system and tap F8 key repeatedly until you see Advanced Boot Options menu on your screen. If you miss reaching the screen in the first attempt, repeat this step until you reach the screen.
2.On the Advanced Boot Options screen, select "Safe Mode with command prompt"
3.In the command prompt window, type "SFC /scannow" (without quotes).
Note: There is a space between C and / in the command above.

This will scan all your protected system files and replace the corrupted files with a cached copy stored in your system.
Important: Please do not close the command prompt window until the verification is 100% complete. After the process is completed, the scan results will be displayed on your screen.

To know more about System File Checker, you can refer to the following Microsoft support page:
http://support.microsoft.com/kb/929833

Hope this will help you.

My certified data laptop quit all of a sudden and turning it off and on or even removing the battery does not help it just goes to safe mode or open windows normal and the screen stays blank


Symptoms seem to indicate either corrupted or missing driver files (probably other corrupted files on hard drive as well).

You can boot into Safe Mode, then run Command Prompt, and type the following to try to correct corruption on the hard drive:
chkdsk c: /r

You will get a message telling you the drive is in use, and would you like to run on next restart. Type "Y" and hit enter, then restart the computer. Depending on the size of your hard drive, this could take hours to run, but be patient.

If this does not resolve your problem, the next thing to try is (in Command Prompt again) "sfc /scannow". You will need your installation disks as this program does a full System File Check and will ask for your installer CD/DVD to replace any missing or corrupt System files it finds.

I hope this helps...

To resolve this problem, replace the missing or corrupted Ntfs.sys file:
  1. Use the Windows Vista startup disks or the Windows Vista CD to restart your computer.
  2. When the "Welcome to Setup" screen appears, press R to select the To repair a Windows Vista installation using Recovery Console, press R option.
  3. Type the number of the Windows installation that you want to access from the Recovery Console, and then press ENTER.
  4. Type the administrator password when you are prompted, and then press ENTER. If no administrator password exists, just press ENTER.
  5. At the command prompt, type the following commands (press ENTER after each command): cd \windows\system32\drivers

    ren ntfs.sys ntfs.oldNote This step renames the corrupted Ntfs.sys file to Ntfs.old. If the Ntfs.sys file is not found, the file is missing.
  6. At the command prompt, type the following command, and then press ENTER: copy cd:\i386\ntfs.sys drive:\windows\system32\driversWhere cd is the drive letter for the CD-ROM drive that contains the Windows Vista CD, and drive is the drive where you installed Windows Vista .
  7. Remove the Windows Vista CD from your CD-ROM drive, type quit at a command prompt, and then press ENTER to quit the Recovery Console.
  8. Restart the computer.

Ntldr is missing press clt alt del to restart


The NTLDR and Ntdetect.com files are important system files that are used by your computer to start the Windows XP operating system. These files can become damaged, corrupted or deleted for a number of reasons and are usually brought to your attention by the "NTLDR is Missing" error message. 

Follow these easy steps to restore the damaged/corrupted or missing NTLDR and Ntdetect.com files from the Windows XP CD using the Recovery Console. 

Time Required: Restoring the NTLDR and Ntdetect.com files from the Windows XP CD usually takes less than 15 minutes

Here's How:

Boot your system  using a Windows XP CD, press any key when the windows display "press any key to boot from CD"and wait for some time, select "r" option to go to recovery console. it will ask you for administrator password too.

When you reach the command prompt type the following two commands, pressing Enter after each one: 
copy d:\i386\ntldr c:\
copy d:\i386\ntdetect.com c:\

In the command listed above, d represents the drive letter assigned to the optical drive that your Windows XP CD is currently in. While this is most often d, your system could assign a different letter. Also, c:\ represents the root folder of the partition that Windows XP is currently installed on. Again, this is most often the case but your system could be different. 

If you're prompted to overwrite either of the two files, press Y. 

Take out the Windows XP CD, type exit and then press Enter to restart your PC. 

Assuming that missing or corrupt versions of the NTLDR and/or Ntdetect.com files were your only issues, Windows XP should now start normally.

That's it.

I cant start my computer because system32\driver\isanpn.sys is missing or corrupt


You need to replace that missing or corrupt system file. If you don't have your disk, you can borrow someone else's Windows XP disk (SP2) because you will need an XP disk to access the recovery console to replace isanpn.sys file.

Here's a link to the full steps on Microsoft's website to go to the recovery console and replace that file:

Missing or corrupted file C:\windows\himem.sys


If you are running Windows 95, Windows 98, type:
copy himem.sys c:\windows <press enter>
If when typing any of the above commands you receive a prompt that the file already exists, ensure to overwrite it.
Reboot the computer; if the issue continues to occur, verify that the config.sys is properly setup. The line himem.sys should read:
DEVICE=C:\Windows\HIMEM.SYS
or
DEVICE=C:\DOS\HIMEM.SYS
Additional information and examples of the config.sys can be found on our autoexec.bat / config.sys page.
