There are three reasons why you may need to install a new copy of Windows XP:
Your current operating system doesn’t support an upgrade to Windows XP Professional.
Your current operating system supports an upgrade to Windows XP Professional, but you don’t want to keep your existing files and personalized settings.
Your computer does not have an operating system.
The setup process is similar for new installations and upgrades with a few notable exceptions. For example, during a new installation, you are able to configure Special Options, convert your file system, and create a new partition for the Windows XP installation.
IMPORTANT
A new installation deletes all programs or system files from a previous installation.
Special Options
Under Special Options, you have the choice to change Language, Advanced, and Accessibility settings during the setup process.
Note: If you are in a country that has recently adopted the euro as its currency, you may have to modify the currency settings to display monetary amounts correctly.
For more information, go to Help and Support Center and type “euro” in the Search box.Select If you want to...
Language Choose the primary language and regions for Windows XP, which affects the default settings for date, time, currency, numbers, character sets, and keyboard layout.
Choose additional language groups and character sets to use with the programs you are running on Windows XP.
Advanced Options Change the default location of the Setup files.
Store system files in a folder other than the default (Windows) folder
Copy the installation files from the CD to the hard disk.
Accessibility Use Narrator or Magnifier during Setup.
IMPORTANT
Unless you're an advanced user, it's recommended that you use the default settings.
Choosing a File System
During a new installation of Windows XP, you may have to choose which file system your computer should use. Windows XP Professional supports:
FAT32: An enhanced version of the file allocation table (FAT) system that is standard on all Windows operating systems starting with later (32-bit) versions of Windows 95. The FAT32 system can be used on large hard disks, from 512 megabytes (MB) to 32 gigabytes (GB).
NTFS: The NT file system (NTFS) is used with the Windows NT, Windows 2000, and Windows XP operating systems. NTFS provides enhanced reliability, stability, and security, and supports large hard disks of up to 2 terabytes (TB).
IMPORTANT
You can convert your file system any time, even after you install Windows XP, without losing any of your data.
The conversion to NTFS is one–way only; if you convert your FAT or FAT32 file system to NTFS you can’t convert your hard disk back to FAT later.
If you’re not sure which file system to use, keep the one your computer defaults to during Setup. If you want to change your file system, here are a few recommendations:
Use FAT32 if your hard disk is smaller than 32 GB.
Use FAT32 if you want to install more than one operating system on your computer.
Use NTFS if your hard drive is larger than 32 GB and you are running only one operating system on your computer.
Use NTFS if you want enhanced file security.
Use NTFS if you need better disk compression.
Disk Partitions
You can create partitions to organize information—for example, to back up data—or to install more than one operating system on your computer. A hard disk can contain up to four partitions.
If you’re performing a new installation, the appropriate disk partition is selected automatically during Windows XP Setup unless you click Advanced Options and specify your own requirements
For more information about configuring, sizing, reformatting, or converting disk partitions, see your current online Help before you install or upgrade to Windows XP Professional.
