How to delete all partitions in windows 11?

Using diskpart to delete all partitions in Windows 11 is powerful—but it comes with risks and limitations that may make it unsuitable for casual or inexperienced users. Here are the main reasons why you might not want to use diskpart.

1. No Undo or Confirmation Prompts

diskpart executes destructive commands like clean immediately without confirmation or the ability to undo. If you select the wrong disk and run clean, you'll permanently lose all partitions and data—even before realizing the mistake.

2. Complex and Risky for Beginners

Unlike graphical tools, diskpart has no visual interface, making it easy to misidentify disks. Beginners can easily:

• Select the wrong disk (select disk X)
• Confuse clean with clean all
• Delete the system drive by accident

3. No Data Recovery or Preview

diskpart does not warn about what's inside a partition, nor does it offer a preview. Once executed, all partitions and file systems are immediately wiped, making recovery difficult without specialized software.

Use diskpart only to delete all partitions on Windows 11 without losing data if you're confident and need full manual control like when scripting disk setup, prepping drives for OS deployment, or working in recovery mode.
