The ability to wipe out the hard drive and reinstall Windows 10 on your computer is usually the recommended method to improve system performance when the system is not working correctly, running slow, or you’re dealing with battery problems. Also, the process of removing everything and starting fresh with a new installation can help you get rid of tough viruses, or prepare the device when you’re planning to find a new owner without giving away your information.
Whatever the reason it might be, on Windows 10, there are at least two ways to erase and start from scratch with a fresh copy of the operating system. You can use the “Reset this PC” feature, which allows you to reset the system to the factory default settings removing everything from all the drives without the need of a USB installation and additional steps. Or you can use a USB bootable media to start the computer to manually wipe out the hard drive and perform a clean installation of the operating system.
In this guide, you’ll learn two methods to securely erase the hard drive and reinstall Windows 10.
- Erase hard drive and reinstall Windows 10 with Reset this PC
- Erase hard drive and reinstall Windows 10 with USB media

After you complete the steps, the hard drive will be wiped out and a clean copy of Windows 10 will be installed on the device. Also, after the installation, you’ll need to complete the out-of-box experience (OOBE) to finish setting up your account and personal settings. However, if you are intending to decommission or sell the computer, you don’t need to go through the steps to complete the setup.
While there are multiple ways to erase the hard drive and reinstall the operating system, using the USB bootable media is perhaps the best option to complete the process since it allows you to manually wipe out the drive and the installation process is likely to cause less problems than using the reset option.
