Wiping a hard drive from the BIOS is a process that involves erasing all data from the hard drive at a low-level, including the operating system, partitions, and all data stored on the drive. This can be useful if you want to securely erase your hard drive before selling or disposing of it, or if you’re experiencing issues that require a complete wipe and reinstallation of the operating system. Here’s how to wipe a hard drive from the BIOS:

- Backup your data Before wiping your hard drive, it’s important to backup any important data that you want to keep. This includes documents, photos, videos, and any other files that you want to keep. You can backup your data to an external hard drive, a cloud-based storage service, or another computer on your network.
- Enter the BIOS To wipe your hard drive from the BIOS, you need to access the BIOS settings on your computer. The process for accessing the BIOS varies depending on the manufacturer of your computer, but it usually involves pressing a key (such as F2, F10, or Del) during startup. Look for a message on the screen during startup that tells you which key to press to enter the BIOS.
- Locate the hard drive settings Once you’re in the BIOS settings, you need to locate the hard drive settings. This may be located in a “Storage” or “Advanced” section of the BIOS settings. Look for a setting that says “SATA Configuration”, “Drive Configuration”, or something similar.
- Disable Secure Boot If your computer has Secure Boot enabled, you need to disable it before you can wipe the hard drive. Secure Boot is a security feature that prevents unauthorized operating systems from booting on your computer. To disable Secure Boot, look for a setting in the BIOS that says “Secure Boot” or “UEFI Boot”. Set this to “Disabled”.
- Change the boot order To wipe your hard drive, you need to boot from a bootable media that contains a disk wiping tool. This can be a USB flash drive, a CD or DVD, or a network boot image. To change the boot order, look for a setting in the BIOS that says “Boot Order”, “Boot Sequence”, or something similar. Set the boot order so that the device containing the wiping tool is first in the boot order.
- Save changes and exit After making changes to the BIOS settings, be sure to save the changes before exiting. Look for a setting that says “Save Changes and Exit” or something similar. Confirm that you want to save the changes and exit the BIOS.
- Boot from the wiping tool After exiting the BIOS, your computer should boot from the wiping tool you selected. Follow the instructions provided by the wiping tool to erase your hard drive. Be sure to select the hard drive you want to wipe, as the wiping tool will erase all data on the selected drive.
- Reinstall the operating system After wiping your hard drive, you need to reinstall the operating system and any other software that you want to use. Insert the installation media for your operating system (such as a Windows DVD or USB drive) and boot from it. Follow the instructions provided by the installer to install the operating system.
In summary, wiping a hard drive from the BIOS involves accessing the BIOS settings on your computer, disabling Secure Boot, changing the boot order to boot from a wiping tool, and following the instructions provided by the wiping tool to erase your hard drive. After wiping your hard drive, you need to reinstall the operating system and any other software you want to use. Remember to backup any important data before wiping your hard drive, as the wiping process will erase all data from the drive.
