Manufacturers haven't included recovery DVDs with personal computers for years, but now more are now leaving out recovery software which will create them for you. Without a recovery disk, or a USB stick that does the same job, you'll be up for a large bill if your computer suffers a hard disk drive failure.
If you've got recovery media you're up for the cost of a hard disk drives, if you haven't you'll be up for the cost of a new computer operating system as well. Microsoft knows this and has now included a tool to create full blown recovery media: a copy of Windows 8 or 8.1, depending on which you are running, on DVD or USB stick.
Such recovery media take a couple of hours to create and could save you a pretty penny.
It's easy to set up and can be created by typing the word "recovery" from the Windows 8 Start screen. Click "Settings" and then "Create a recovery drive". If you have a recovery partition on your computer you will be given the option to "Copy the recovery partition from the PC to the recovery drive". Tick this box if you can, otherwise only system repair tools are created. Then click "Next".
You'll probably need a USB stick of about 16GB, but in rare instances 32GB is necessary. Or you can use DVDs if your machine has an optical disk drive. Be sure to label your USB stick, or DVDs, and store them in a safe place for if you ever need them.
