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 won’t boot because the partition boot sector has been corrupted, you can use a special Recovery Console tool called Fixboot to fix it.
Start by accessing the Recovery Console.
To use the Fixboot tool, from the Recovery Console command prompt, type
Where [drive] is the letter of the drive to which you want to write a new partition boot sector.
System Restore is an extremely helpful tool built into Windows XP and Vista. System Restore runs in the background as a service and continually monitors system-critical components for changes. When it detects an impending change, System Restore immediately makes backup copies, called restore points, of these critical components before the change occurs. In addition, System Restore is configured by default to create restore points every 24 hours.
To use System Restore, first restart the computer by pressing [Ctrl][Alt][Delete]. When 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, select the Safe Mode item from the menu and press [Enter].
Once Windows boots into Safe mode, click the Start button, go to All Programs -> Accessories -> System Tools, and select System Restore. Because you’re running in Safe mode, the only option on the opening screen of the System Restore wizard is Restore My Computer To An Earlier Time, make sure it’s selected and click Next. Follow along with the wizard to select a restore point and begin the restoration procedure.
Confirm the date and time selected and click Next. Windows will perform the restoration and shut down. After the restoration Windows will restart and inform you that the restoration completed successfully. Click OK to continue the startup process.
When Windows 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. Then, select the Disable The Automatic Restart On System Failure item and press [Enter]. Now, Windows 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.
When a Windows XP system wont boot up, you can often fix the problem using the Recovery Console. The Windows XP CD is bootable and will provide you with access to this tool.
To boot from the Windows XP CD, insert it into the CD-ROM drive on the problem system and reboot the computer. The system should present you with the option to boot from the CD, simply follow the prompts that will allow the loading of the basic files needed to run Setup. If not, you will need to access the BIOS and enable booting from your CD or DVD drive.
When you see the Welcome To Setup screen, shown below, press R to start the Recovery Console.
You’ll then see a Recovery Console menu, like the one shown below. It displays the folder containing the operating system’s files and prompts you to choose the operating system you want to log on to. Just press the menu number on the keyboard, and you’ll be prompted to enter the Administrator’s password. You’ll then find yourself at the main Recovery Console prompt.
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 your master boot record has been corrupted, you can use the Recovery Console tool Fixmbr to fix it. First, boot the system with the Windows XP CD and access the Recovery Console
To use the Fixmbr tool, from the Recovery Console command prompt, type
Where [device_name] is the device pathname of the drive to which you want to write a new master boot record. For example, the device pathname format for a standard bootable drive C configuration would look like this:
