Do you mean to reset a hard drive ready to install Windows 8.1 or Windows 10 from BIOS? If you need to format the hard drive from the BIOS without booting Windows, you'll have to use a Windows installation USB drive to do so.

Step 1. Connect a bootable USB drive to the targeted PC, restart your PC, and press F2 to Enter the BIOS.

Step 2. Set the USB flash drive as the boot disk, and wait for the Windows installation medium to open.

Step 3. Then, navigate to Troubleshoot > Advanced > Command Prompt.

Step 4. Type one of the following commands and press Enter:

  • diskpart
  • list volume
  • exit
  • dir C: (replace C with the letter of your OS drive)
  • format C: /fs:NTFS (replace C: with the letter of the targeted drive)
  • y

Don't have much experience in command lines? It's okay. Actually, it is an easy job as long as you use a reliable tool. After my various tests, I found a trustworthy third-party tool, EaseUS Partition Master. It can help you create a bootable USB and then help you format a hard drive or a disk from BIOS. Its clear interface makes this process short and easy. You don't have to type any commands during the process.
