which are the steps for formating laptop windows 7 without cd

Solution
Most laptops have a hidden partition on the hard drive which contains the "Factory Recovery" data to restore the laptop with a fresh installation of Windows plus drivers. To start the factory recovery process you have to press a specific key at boot time, the actual key varies from one manufacturer to another, so check your laptop manual or go their website for support.

If there is no recovery partition on the hard drive (eg if you've had to replace a failed hard drive), contact the manufacturer and ask them if they can supply a set of recovery discs for your model.
