The partition boot sector is a small section of the hard disk partition that contains information about the operating system's file system NTFS or FAT32 , as well as a very small machine language program that is crucial in assisting the operating system as it loads.
If you suspect that Windows XP won't boot because the partition boot sector has been corrupted, you can use a special Recovery Console tool called Fixboot to fix it. The master boot record occupies the first sector on the hard disk and is responsible for initiating the Windows boot procedure. The master boot record contains the partition table for the disk as well as a small program called the master boot code, which is responsible for locating the active, or bootable, partition, in the partition table.
Once this occurs, the partition boot sector takes over and begins loading Windows. If the master boot record is corrupt, the partition boot sector can't do its job and Windows won't boot. If you suspect Windows XP won't boot because the master boot record has been corrupted, you can use the Recovery Console tool Fixmbr to fix it. For example, the device pathname format for a standard bootable drive C configuration would look like this:. When Windows XP encounters a fatal error, the default setting for handling such an error is to automatically reboot the system.
If the error occurs while Windows XP is booting, the operating system will become stuck in a reboot cycle--rebooting over and over instead of starting up normally. In that case, you'll need to disable the option for automatically restarting on system failure. When Windows XP begins to boot up and you see the message Please select the operating system to start or hear the single beep, press [F8] to display the Windows Advanced Options Menu.
Now, Windows XP will hang up when it encounters the error and with any luck, it will display a stop message you can use to diagnose the problem. If you can't seem to repair a Windows XP system that won't boot and you have a recent backup, you can restore the system from the backup media. The method you use to restore the system will depend on what backup utility you used, so you'll need to follow the utility's instructions on how to perform a restore operation.
If you can't repair a Windows XP system that won't boot and you don't have a recent backup, you can perform an in-place upgrade. Doing so reinstalls the operating system into the same folder, just as if you were upgrading from one version of Windows to another. An in-place upgrade will usually solve most, if not all, Windows boot problems.
This screen will prompt you to press R to repair the selected installation or to press [Esc] to install a fresh copy of Windows XP. In this case, initiating a repair operation is synonymous with performing an in-place upgrade, so you'll need to press R.
