There are a lot of reasons why people don’t like Windows Vista and decide to downgrade to an earlier version of Windows such as Windows 2000 or Windows XP. Vista tends to be somewhat sluggish on older computers and it also tends towards the nanny-like protection for which Microsoft is famous. Unfortunately, Microsoft does not allow downgrades directly from Vista. Instead, you must first wipe Vista out and then install Windows 2000.
Copy all your vital files onto blank CDs. This includes anything that cannot be replaced except program files or system files. You will simply re-install those once you are done.
Consult your user manual and find out how to enter BIOS. Often, the F2 key will allow you to do so. Enter the BIOS and change the boot sequence to boot from the CD drive first.
Insert the Vista disk and boot from it. Follow the prompts to reinstall Vista. When the system asks if you'd like to wipe away your hard drive and completely re-install Vista (as opposed to simply repairing it), choose to re-install. Once it says it has finished formatting your hard drive, either press the reboot button on your computer or turn it off completely.
If you turned your computer off, turn it back on again. Remove the Vista disk from your CD drive and insert the Windows 2000 disk. Depending on how quickly you do this, you may need to reboot again. If the screen gives you an error of "no operating system found" then you'll need to reboot. When you have rebooted the computer, it should boot from your Windows 2000 disk. Follow the prompts to install the software.
Transfer your vital files back and re-install your programs once Windows 2000 is installed.
- Often, you do not need to access BIOS since the computer is pre-set to boot from the CD. Just press any key when it asks if you want to boot from CD.
- You will permanently lose anything on your computer that you do not back up, so be sure you copy everything you think you may need.
