Alternatively, holding the Shift key while clicking “Restart” in the login screen may also lead to this menu.

Using the Command Prompt to Format the Drive:

In the Advanced Startup Options menu, select “Troubleshoot” and then “Advanced options.”
Choose “Command Prompt.”
The command prompt window will appear.

Commands to Format the Drive:

First, use the diskpart command to manage the disks. Type diskpart and press Enter.
Next, list the available disks using the list disk command. Identify the disk number corresponding to your laptop’s hard drive.
Select the disk you want to format using the select disk X command, where X is the disk number.
Clean the disk using clean. This command removes all partition and volume information from the disk.
Create a new primary partition: create partition primary
Select the newly created partition: select partition 1
Format the partition using the format fs=ntfs quick command. This will perform a quick format of the partition with the NTFS file system. For a more thorough format, omit the quick option.
Assign a drive letter: assign letter=C
Exit diskpart by typing exit and pressing Enter.

Caution: Be extremely careful when using the diskpart command, as incorrect commands can lead to data loss on the wrong drive. Double-check the disk number before selecting and cleaning the disk.

Security Considerations After Formatting
