How to Wipe hard drive on my Windows 7 computer?

This method uses Windows built-in tool called Diskpart. It’ll completely wipe hard drive on Windows 7 PC without needing any additional software.

1. Backup Your Data:

• Before you start, make sure to back up any important files. Once wiped, everything will be gone!

2. Create Windows Installation Media (if needed):

• If you want to reinstall Windows afterward, you’ll need a Windows 7 installation DVD or a USB drive. If you don't have one, you can create it using the Windows USB/DVD Download Tool with the Windows ISO.

3. Boot from Installation Media:

• Insert your installation disc or USB, and restart your computer.
• Enter the boot menu (usually F12, F2, DEL, or ESC depending on your machine) and choose to boot from the installation media.

4. Access Command Prompt:

• Once it loads, choose your language and select “Repair your computer.”
• In the System Recovery Options, click on “Command Prompt.”

5. Use Diskpart:

• In the Command Prompt window, type the following commands: diskpart
• To see a list of drives, type: list disk
• Identify your hard drive (usually Disk 0) and select it. For example: select disk 0
• Now, wipe the drive by typing: clean all
• The clean all command will take more time as it overwrites the data, ensuring it’s gone for good.

6. Exit Diskpart: exit

7.Reboot Your System:

• If you don’t plan to reinstall Windows, you can shut down the computer after this step. If you are, continue with the installation process.
