i have a dos laptop on which i installed windows 8.Will the windows be uninstalled if i do a factry reset

Solution
Whatever OS was on the system originally should be what it resets to. If that was DOS only, then that is what it will go back to. Or if it was another version of Windows, same thing.

The reset would come from either a separate partition on your drive, or your installation disk(s). If you have them.

Unless you had previously completely wiped the drive, or replaced it, and only had DOS on it, then it should go back to that.
