In this post I explain how to reinstall factory operating system on different laptops. This should work for most laptops running Windows Vista or Windows 7 operating systems.
This could be useful if your operating system stopped working properly, got corrupted or infected with a virus.
WARNING! Running system restore utility will erase all personal data on the hard drive and re-image it back to factory defaults. Make sure all personal data is backed up before reinstalling the operating system. Also, make sure the laptop is running on AC adapter power during the recovery process.
These days most laptops are sold without recovery discs. Instead they have a hidden (or visible) recovery partition with the factory image. In order to re-image the hard drive back to factory defaults it’s necessary to initiate the recovery wizard and it’s very similar for many different laptop brands.
As an example I’ll show step-by-step operating system re-installation process on HP laptops.
Again, it will be the same or very similar for other laptop brands.
