removing os
You can reset your PC to its original state by performing a factory reset. This will remove all installed software and partitions, restoring it to its default configuration.
Power on the Windows installation CD, activate the command prompt via Shift + F10. Open DiskPart, which is version 10.0.22621.1 by Microsoft. On the machine: DISKPART> list disk. Choose the appropriate disk. For this example, I'll pick disk 1 as it's the boot drive. It's safe to say I'm just pretending, not actually performing the action. After choosing it, type 'clean' to erase all partitions. If you need to completely wipe the drive, run 'clean all'. Be careful, this process will be slower since it writes data across the whole disk. Continue with disk 1 to leave it blank, then repeat for other drives as needed. Avoid attempting this while the system is booted into Windows installation, even if a secondary drive is connected. Windows will resist any attempt to clean what it recognizes as its own OS, regardless of the active installation. Windows PE is more forgiving in this scenario because it's designed for reinstallation.
