Issue: Fix a corrupt Boot.ini

As the Windows XP operating system begins to load, the Ntldrprogram refers to the Boot.ini file to determine where the operating systemfiles reside and which options to enable as the operating system continues toload. So if there's a problem rooted in the Boot.ini file, it can render WindowsXP incapable of booting correctly.

If you suspect that Windows XP won't boot because Boot.inihas been corrupted, you can use the special Recovery Console version of theBootcfg tool to fix it. Of course, you must first boot the system with theWindows XP CD and access the Recovery Console as described in #4.

To use the Bootcfg tool, from the Recovery Console commandprompt, type
Bootcfg /parameter
Where /parameter is one of these required parameters:

• /Add--Scans the disk for all Windowsinstallations and allows you to add any new ones to the Boot.ini file.
• /Scan--Scans the disk for all Windowsinstallations.
• /List--Lists each entry in the Boot.ini file.
• /Default--Sets the default operating system as themain boot entry.
• /Rebuild--Completely re-creates the Boot.inifile. The user must confirm each step.
• /Redirect--Allows the boot operation to beredirected to a specific port when using the Headless Administration feature.The Redirect parameter takes two parameters of its own, [Port Baudrate ] | [UseBiosSettings].
• /Disableredirect--Disables the redirection.

Issue: Fix a corrupt partition boot sector
The partition boot sector is a small section of the harddisk partition that contains information about the operating system's filesystem (NTFS or FAT32), as well as a very small machine language program thatis crucial in assisting the operating system as it loads.
If you suspect that Windows XP won't boot because thepartition boot sector has been corrupted, you can use a special RecoveryConsole tool called Fixboot to fix it. Start by booting the system with theWindows XP CD and accessing the Recovery Console as described in #4.

To use the Fixboot tool, from the Recovery Console commandprompt, type

Fixboot [drive]:

Where [drive] is the letter of the drive towhich you want to write a new partition boot sector.

Issue: Fix a corrupt master boot record
The master boot record occupies the first sector on the harddisk and is responsible for initiating the Windows boot procedure. The masterboot record contains the partition table for the disk as well as a smallprogram called the master boot code,which is responsible for locating the active, or bootable, partition, in thepartition table. Once this occurs, the partition boot sector takes over andbegins loading Windows. If the master boot record is corrupt, the partitionboot sector can't do its job and Windows won't boot.

If you suspect Windows XP won't boot because the master bootrecord has been corrupted, you can use the Recovery Console tool Fixmbr to fixit. First, boot the system with the Windows XP CD and access the RecoveryConsole as described in #4.

To use the Fixmbr tool, from the Recovery Console commandprompt, type
Fixmbr [device_name]

Where [device_name] is the devicepathname of the drive to which you want to write a new master boot record. Forexample, the device pathname format for a standard bootable drive Cconfiguration would look like this:

\Device\HardDisk0
