How can install xp by command prompt?

To install Windows XP via the command prompt, you need to boot from the Windows XP installation CD. Once the setup starts, press R to enter the Recovery Console, and then you can access the command prompt. However, installing Windows XP typically requires the use of the graphical setup interface instead of solely relying on the command prompt. To proceed with a full installation, follow the on-screen prompts after booting from the CD.
