Options for partitioning and formatting your hard disk

Consider the following questions before you partition and format your hard disk:
 

• Have you prepared the hard disk by following the manufacturer's instructions?
  
  Set the jumpers and the cabling according to the role of the hard disk (for example, master or subordinate) and make any required BIOS (or CMOS) changes. See the documentation that came with your hard disk and motherboard, or contact the manufacturers.
  
   
• What type of file system do you want to use?
  
  You can use either the FAT or NTFS file systems.
  
  For additional information about the differences between the FAT and NTFS file systems, click the following article numbers to view the articles in the Microsoft Knowledge Base:

• Does the hard disk already contain data? If yes, have you backed up all your important data?
  
  If not, back up your data before you continue. When you partition and format a hard disk, all the data on that partition is permanently deleted. You can view current partition information without deleting your data.

• Does the hard disk have a drive overlay or a disk management program?
  
  If your computer uses drive overlay software for large hard disk support, do not use the Windows XP Setup program to partition or to format the drive until you have verified Windows XP compatibility with the software manufacturer. If you do not know whether you have drive overlay software installed, contact the software manufacturer before you continue.
• Do you have the floppy disks or the CD-ROMs that you need to reinstall your software?
  
  Make sure that you have the software so that you can reinstall your programs after you partition and format your drive. If you purchased an upgrade for a program, make sure that you have the full version of the original program. Many upgrades for programs require a compliance check before you can install the upgraded product. If you cannot find the original floppy disks or CD-ROMs, contact the software manufacturer before you continue.
• Do you have updated device drivers backed up on storage other than the drive that you want to format and partition?
  
  If you have installed an updated device driver for your peripheral devices (for example, modems and printers), make sure that you back up the new driver for the device to a location other than the drive that you want to format and partition. Therefore, you can reinstall it after you install your operating system.
• Can you start your computer from the CD-ROM drive?

Important If you follow these steps on a hard disk that is not empty, all the data on that hard disk is permanently deleted. We recommend that you back up your hard disk before you follow these steps.

To partition and format your hard disk by using the Windows XP Setup program:

1. Insert the Windows XP CD-ROM into your CD-ROM drive or DVD-ROM drive, or insert the first Windows XP Setup disk into the floppy disk drive, and then restart the computer.

Note To start your computer from the Windows XP CD-ROM (or from the startup disk), your computer must be configured to start from the CD-ROM drive, the DVD-ROM drive, or the floppy disk drive. In some cases, you may have to modify your computer's BIOS settings to set this configuration. For information about how to configure your computer to start from the CD-ROM drive, the DVD-ROM drive, or the floppy disk drive, see the documentation that is included with your computer, or contact the computer manufacturer.

2. If you are starting the computer from the Windows XP CD-ROM, select any options that are required to start the computer from the CD-ROM drive if you are prompted to do this.

Note If your hard disk controller requires a third-party original equipment manufacturer (OEM) driver, press F6 to specify the driver.

For additional information about how to use F6 to supply a third-party OEM device driver while the Windows Setup program is running, click the following article number to view the article in the Microsoft Knowledge Base:

314859 Limited OEM driver support is available with F6 during Windows XP Setup If you are starting from the Windows XP Setup disks, insert each of the additional disks when you are prompted, and then press ENTER to continue after you insert each disk.

3. At the Welcome to Setup page, press ENTER.

4. Press F8 to accept the Windows XP Licensing Agreement.

5. If an existing Windows XP installation is detected, you are prompted to repair it. To bypass the repair, press ESC.

6. All the existing partitions and the unpartitioned spaces are listed for each physical hard disk. Use the ARROW keys to select the partition or the unpartitioned space where you want to create a new partition. Press D to delete an existing partition, or press C to create a new partition by using unpartitioned space. If you press D to delete an existing partition, you must then press L (or press ENTER, and then press L if it is the System partition) to confirm that you want to delete the partition. Repeat this step for each of the existing partitions that you want to use for the new partition. When all the partitions are deleted, select the remaining unpartitioned space, and then press C to create the new partition.

Note If you want to create a partition where one or more partitions already exist, you must first delete the existing partition or partitions, and then create the new partition.

7. Type the size in megabytes (MB) that you want to use for the new partition, and then press ENTER, or just press ENTER to create the partition with the maximum size.

8. Repeat Steps 4 and 5 to create additional partitions if you want them.

9. If you want to install Windows XP, use the ARROW keys to select the partition where you want to install Windows XP, and then press ENTER. If you do not want to format the partition and install Windows XP, press F3 two times to quit the Windows Setup program, and then do not follow the remaining steps. In this case, you must use a different utility to format the partition.

10. Select the format option that you want to use for the partition, and then press ENTER. You have the following options:

 

• Format the partition by using the NTFS file system (Quick)
• Format the partition by using the FAT file system (Quick)
• Format the partition by using the NTFS file system
• Format the partition by using the FAT file system
• Leave the current file system intact (no changes)
