    NTLDR Missing

     

    This error occurs when the partition marked as active does not contain the operating system boot files. The partition for the OS must be a primary partition that has been marked as active. If it is a SCSI, SATA or RAID drive the appropriate drivers need to have already been installed. The boot partition must be located on the disk pointed to in the BIOS boot sequence. The below advice is for single boot systems. Some exceptions apply if you have a dual boot setup..

     

    So, two issues:

     

    1. Having the PC boot from the correct drive, properly partitioned with the boot partition set as "Active".

     

    2. Having the right files in that partition.

     

    You can change the active partition using fdisk. And you can change the first boot device (but using an optical drive with a Windows CD to boot from can cause you problems later) in the BIOS.

     

    Using fdisk:

     

    1. Boot to a command prompt by using a boot disk (if you have one. Otherwise you can make one from any Windows 95/98/ME PC.

    2. At the command prompt, type fdisk, and then press enter.

    3. Click set active partition, choose the partition that you want to make active, and then hit enter.

    4. Press Esc.

    5. Remove the boot floppy disk, restart the computer.

     

    Right Files:

     

     

     

     

    Using the Recovery Console, copy the Ntldr file from the Windows XP CD-ROM to the root directory of the current active partition. Follow these steps:

    1. Start your computer by using the Windows XP Setup floppy disks or by using the Windows XP CD-ROM.

    2. At the "Welcome to Setup" screen, press F10, or press R to repair.

    3. Press C to start the Recovery Console.

    4. Copy the Ntldr file from the Windows XP CD-ROM to the root of your system partition by using the following commands, pressing ENTER after each command:

     

    1. Type cd .. to go to the root of drive C. (Note the space)

    2. Type the letter of the CD-ROM drive

    3. Type cd i386 to change into the right directory

    4. Type Copy ntldr c:

    5. Type Exit

     

    If the partition was not formatted by using Windows, you might also need to run the Recovery Console fixboot command to make the active partition bootable.

     

    After you can boot into Windows, it is recommended that you use the Windows Disk Management snap-in tool to reset the original system partition as the active partition, and then restart the computer.

     

    From Microsoft:

     

    If the NTLDR is missing or damaged try the Recovery Console.

     

    To start the computer and use the Recovery Console to replace the boot sector

     

    "Insert the Windows XP Professional Setup CD-ROM into the CD-ROM drive.

     

    Restart the computer. If prompted to press a key to start the computer from the CD-ROM, press the appropriate key.

    When the text-based part of Setup begins, follow the prompts. Press the R key to repair a Windows XP Professional installation.

    If you are repairing a system that has more than one operating system installed, from the Recovery Console choose the Windows XP Professional installation that you need to repair.

    Note

     

    If you press ENTER without typing a number, the Recovery Console quits and restarts the computer.

     

     

    The Recovery Console might also show valid installations of Windows NT 4.0. However, the results of attempting to access a Windows NT 4.0 installation can be unpredictable.

     

    When prompted, type the Administrator password. If you do not have the correct password, or if the security database for the installation of Windows XP Professional that you are attempting to access is corrupted, Recovery Console does not allow access to the local disks and you cannot replace the boot sector.

     

    To replace the boot sector, at the Recovery Console command prompt, type: fixboot [drive:]

     

    If you do not specify a drive letter, the Recovery Console replaces the boot sector of the system volume. If you need to replace the boot sector of a volume that is not the system volume, then you must specify the appropriate drive letter."

     

    ... More Microsoft NTLDR Help

     

    "Using Recovery Console enables you to recover from the following problems:

     

    Corrupted or deleted startup files caused by incompatible software, user error, or virus activity.

     

    Disk problems related to damage to the master boot record (MBR), partition table, or boot sector on x86-based systems.

     

    A partition boot sector overwritten by another operating system's setup program.

     

    If critical system files, such as Ntldr or Ntoskrnl.exe, are missing or corrupted, you can restore them by starting Recovery Console and copying fresh files from the Windows XP Professional operating system CD or other removable disk media." More

     

     

     

    One user has written in with this feedback:

     

    "I recently encountered the above mentioned 'NTLDR is missing' error

    while starting up my pc and found the solution on your site. Thanks, people! Thing was, all the time I had a floppy in my floppy drive. And my pc is set up to have it's primary boot device be the floppy drive! Maybe you can add this tip to your page- make sure there is no floppy in the drive!"

    I tried it, it slowed my system down. It fortunately can be uninstalled via ADD/REMOVE programs, but it leaves shortcuts, icons and files scattered all over the place. It has some interesting features, like the new Windows Update and the Security Center, but I'll wait for the final release. Fortunately I had an image to restore my system. Be afraid, be very afraid....

    Firewall Settings Requirements:

     

    For ICQ to successfully work behind a firewall the following system configurations must be set by the System Administrator for the systems network.

     

    Client to server Communication:

    This is done via port 5190 TCP to login.icq.com (please note- allow a bi-directional connection to the port for login.icq.com and not any specific IP address, since it stands for more than one IP address).

     

    Client to client communication:

     

    Client to client connection is done using the TCP protocol, using port range 1024-65535. This means that the client needs an open listening port within the mentioned range-- 1024-65535.

    If your Network firewall settings meet the above requirements, you do not to need to configure ICQ to work behind a firewall.

     

     

    In the event that your systems network has difficulty setting the above

    ICQ firewall requirements you may wish to check some of the

    possibilities below for finding a solution to your firewall problem:

     

     

    The TCP Listening Port range is too large

    Minimize the range. you can open a smaller range on your firewall, and then you must configure ICQ to work through the specific port range you have dedicated.

     

     

    In the event you cannot open any TCP listening port

    If you cannot open the TCP listening port but you can open a bidirectional TCP connection to the internet, configure ICQ to work with no listening port.

     

     

     

    Note: Communication between LAN users and any Internet user who cannot open a listening TCP port cannot be accomplished. To prevent this from occurring use Socks4.x.x or Scoks5.x compatible firewalls. This requires the use of a proxy server (Socks4.x/Socks5.x.x).

    The ICQ client must have access to the Socks4.x/Socks5.x.x server, and the server must have full access to an Internet connection, including opened listening TCP ports.

    The Socks server acts like a bridge to the Internet and ICQ is the pedestrian. Otherwise, HTTPS will not be able to carryout peer to peer connection. This means that a web proxy (client) may relay a request to the web servers, but it will not be acknowledged by the servers, therefore no answer will be given to the information request.

     

     

    Your connection to the Internet is done using IP-Masquerading

    This means you cannot open any listening ports, and you need to use the basic firewall configuration. Once again,using this option your users will not be able to communicate with any user who cannot open a TCP listening port. To solve this problem use Socks4.x or Socks5.x Proxy server.

     

     

     

    View ICQ with Socks4.x configuration

     

    View ICQ with Socks5.x configuration

     

    View ICQ with HTTPS configuration
