You can boot off of the WIndows XP cd. before that make sure the cd drive is set as the first boot device in the bios, start the computer with the cd in the drive and when prompted press any key to boot off of the cd. From there you can either format and reinstall Windows or do a repair of the current installation.

This issue may occur if you have a CD, a DVD or a floppy disk in your CD, DVD, or floppy drive when you start the computer. or This issue occurs if one or more of the following elements are corrupted and will not load during the boot sequence of the computer:

• Master boot record
• Partition tables
• Boot sector
• NTLDR file

If you can start the computer from the boot disk without receiving an error message, the damage is limited to the master boot record, the boot sector, or the NTLDR file. After Windows XP is running, immediately back up all data before you try to fix the boot sector.

Use Disk Management to view the partition information and to verify that the disk partition (or partitions) is correct. To use Disk Management, follow these steps:

• Click Start, right-click My Computer, and then click Manage.
• Expand Storage, and then click Disk Management.

If invalid partitions are present or you cannot start your computer by using a boot disk, consider reinstalling Windows XP on your computer and restoring your data and configuration information from a recent backup.

If you do not have a current backup copy of the data on the computer, contact a computer specialist to determine the best method of data recovery and configuration.

1. Run a current virus scanning program to verify that no virus is present.
   
2. Repair the master boot record by using the FIXMBR command from the Windows XP Recovery Console.
   
3. If the primary boot partition is a FAT partition, use the FIXBOOT command from the Windows XP Recovery Console to write a new boot sector on the system partition, and then use the FIXMBR command to repair the master boot record.

If your computer is infected with a virus and you use the FIXMBR command, you may be unable to start the computer. Before you use this command, make sure that the computer is not infected with a virus.
