How to Uninstall Windows XP Then Boot From a Discby Joshua Benjamin
While Windows XP is still one of Microsoft's most popular operating systems, sometimes people will want to remove it to make room for a different OS. When this happens, there are essentially two options for the computer owner. If the version of Windows XP is an upgrade from a previous version of Windows like Windows 95 or 98, then it is a simple matter to just uninstall Windows XP and revert to the older operating system. If, however, no older operating system is present, then the only way to remove Windows XP is to format the hard drive and start over.
Reverting to an Older Version
Turn on your computer, and press "F8" before Windows loads.
Select the "Safe Mode" option.
Access the "Control Panel" through the "Start" menu, and double-click "Add or remove programs."
Scroll down the list of installed programs until you find "Microsoft Windows XP". Double-click "Uninstall Windows XP" to start the uninstall process. Click "Yes" when asked if you really wish to uninstall Windows XP.
Formatting the Hard Drive
Turn on your computer, and insert your Windows XP install disk into your computer's CD drive. Press any key to boot from the Windows XP install disk when prompted.
Follow the on-screen instructions until you reach the point where the setup program asks which partition you wish to install Windows XP onto. Do not select any partitions. Instead, highlight the partition containing your current copy of Windows XP, and press the "D" key to delete the partition.
Press "L" when prompted, to delete the partition. This will erase all the information stored on this partition, so make sure you have backed up any vital information you do not wish to lose before completing this step.
Exit the Windows XP Install program.
Booting from a disk.
Restart your computer after uninstalling Windows XP.
Insert the disk you wish to boot from into your computer's CD drive.
Press any key when prompted to boot from the CD.
