How Do I Uninstall Windows XP From My Computer

"How do I uninstall Windows XP from my computer?" is a question with a rather complicated answer. The uninstall process varies depending on how you installed the Windows XP operating system, so you might need to try a few different options.

Back up important files before you uninstall Windows XP.
Before you attempt to uninstall Windows XP, back up important files from your system. Save them to an external storage device or to a second hard drive. You may need to format your hard drive during the uninstall process, and if you haven't backed up important files before you begin this process you may not get an opportunity to save them.

Uninstalling is simple if you saved your old system files.
When you installed Windows XP, you received a prompt asking if you wanted to save old system files. If you saved these files, then uninstalling is relatively easy. You'll need to start your computer in Safe Mode by restarting your computer and pressing the F8 key while Windows is booting up. Once you're in Safe Mode, go to your Start Menu, Control Panel and Add/Remove Programs. From there, click on Uninstall Windows XP, and simply follow the system prompts as you uninstall and revert to your old operating system.

With no backup files, you must manually reinstall your old operating system.
If Uninstall Windows XP doesn't show up on the Add/Remove Programs list, you don't have the necessary backup files, and you've got to reinstall your old operating system manually. If this is the case, beware. Manual installation requires you to reformat your hard drive, which means you'll lose all the files and software on your hard drive. Don't pursue this option unless you've backed up your data and are comfortable reformatting your hard drive. If you're not comfortable with this option, consult Microsoft or a computer repair technician for Windows XP help to resolve your issues.

If you're ready to proceed, put your old Windows operating system disc in your drive-not the Windows XP operating system disc-and put a startup diskette in your floppy drive. Boot from the startup diskette. Different boot startups require different procedures to boot from a floppy, so consult your computer documentation to find out how to boot from a floppy drive.

When you boot, select option one to start your computer with CD-ROM support. Type "dfisk" and press Enter at the A:> prompt. Create a DOS partition, and follow the prompts to create the appropriately sized partition. When you're finished, restart the computer again, type format c: and press enter.

Once that operation is complete, restart the computer again, and select your CD-ROM drive. If your drive is E, type E:, press enter, type dir and press enter again. The directory gives you the name of your Windows installation file. Type CD and the name of the installation file, and press enter. Finally, type Setup, and it should start your new Windows installation.
