Clean Install of Windows 8 or Windows 8.1
- Not Applicable.
- A clean install erases every bit of information on the drive you're going to install Windows 8.
- This means all of the data, programs, and the old Windows files will be erased. This means that the entire operating system that's on there now, whatever that may be, will be gone.
- Backing up your actual programs isn't usually possible, so locate all the installation media and downloaded installation files that you used to install the programs.
- Also backup any data files from your programs, assuming they have any, that might not be located with your other saved files.
- A 25-digit alphanumeric code is required during the Windows 8 clean install process.
- The product key should be included with the DVD media or in the email confirmation you received when you purchased Windows 8 or 8.1 for download.
- If Windows 8 came preinstalled on your computer, look for a sticker with the product key somewhere on the computer.
- If you cannot locate your Windows 8 product key but Windows was preinstalled by your computer manufacturer, then you do have the option of extracting the key from your current installation.
- To start the Windows 8 clean install process, you'll need to boot your computer from whatever installation source you happen to be using: either a DVD disc or a flash drive.
- Insert the Windows 8 DVD into your optical drive, or plug into a free USB port the flash drive with the Windows 8 installation files on it, and then turn on or restart the computer.
- Watch for a Press any key to boot from CD or DVD... message if you're booting from a disc, or a Press any key to boot from external device..
- Press any key to force your computer to boot from either the Windows 8 DVD or a flash drive with the Windows 8 installation files on it. If you don't press a key to force the boot from the external drive or DVD disc, your computer will try to boot from the next device listed in the boot order in BIOS, probably your hard drive, in which case your currently installed operating system will start. If that happens, just restart your computer and try again.
