When you buy your new Windows 7 based computer, one of the first things you need to do is burn a few discs with the System Repair or Recovery on it. It is stored when the computer arrives on your hard drive (C) in the partition (D). (Click My Computer to open it and you will see drive D)
What you are going to do is create a set of DVD discs that will restore your computer to the state it was in when you bought it. This will allow you to restore your computer system in the unlikely event the hard drive crashes. Hard drives are a lot more reliable than they once were, but they will still fail, and this will allow you to go back to day 1 and start over if it ever happens.
So, how do we do that? If you haven’t already done it, go to your Control Panel, and click on “Back up and Restore”.
On the left side panel look for and click on “Create a system repair disc”. A new window will pop up with a very complete description on what you need to do. Step by step. It will take a while, but once it is done you have backed up your entire system. Depending on your system, you may need 4 or 5 discs. Mark the discs you use in the order you burn them, I use a sharpie marker for that. You will also need a bundle of blank DVD discs, get a box of 10 or so to get started with. You will have some left over, but they will get used later. Try to buy a brand name like Sony or Maxell, they seem to have fewer drop outs than the house brand variety. They cost a penny or 2 more, but it is after all your precious data you are protecting. Be sure to get a box complete with jewel cases.
Select either DVD-R or DVD+R, I think the DVD-R is the better choice. Do not use the DVD-RW. Those can be rewritten and you don’t want to do that. (RW=Rewrite) They also take longer to burn.
Once this is done, store the discs in a safe place, rembering of course just where this safe place is in the event you need to use them. (FYI I have had to use them so I know how important they are.)
