If you're looking to wipe your laptop and start over, there are a few things you'll need to do. First, you'll need to back up any important files or data that you don't want to lose. Once you've done that, you can begin the process of wiping your laptop.
To do this, you'll need to access your laptop's BIOS settings. This can usually be done by pressing a key during startup, such as F2 or Del. Once in the BIOS settings, look for an option that says something like Factory Reset or Restore defaults. Select this option and follow the prompts to complete the reset.
Once your laptop has been reset, it will be as if you just bought it new! You can now set it up how you want and install any necessary programs or files.
