Before wiping your PC, prepare the following essentials:

(Usually tied to your Microsoft account or PC hardware.) -
✅ A stable internet connection
For downloading updates or activation. -
✅ A backup of your important files
Because wiping your drive will erase everything.

Here are a few safe backup options:
Option 1: Use OneDrive (Cloud Backup)
-
Open Settings → Accounts → Windows Backup.

Enable Remember my apps and OneDrive folder sync.
-
All your Desktop, Documents, and Pictures folders will be uploaded to the cloud.

Option 3: Use Third-Party Backup Tools
Tools like Macrium Reflect, EaseUS Todo Backup, or Acronis True Image can back up your entire drive (including partitions and system files).
✅ Pro Tip:
Don’t forget to back up browser bookmarks, saved passwords, and emails if they’re stored locally.
⚙️ Step 2: Create Windows 11 Installation Media
To reinstall Windows 11, you’ll need a bootable USB drive.

Let the tool download and prepare your Windows 11 installer.
Method 2: Use an ISO File (Advanced Users)
If you prefer, you can download the ISO file and use Rufus to create bootable media manually.
🔒 Step 3: Securely Wipe Your Hard Drive
Before reinstalling, you’ll want to erase the existing data completely.
Option 1: Wipe During Windows Setup
When you reinstall Windows 11, you can delete all partitions directly from the setup screen (details in Step 6 below).

If you want a secure, deep wipe:

Enter your boot menu (usually by pressing F2, F12, Del, or Esc depending on your manufacturer).

-
Choose the edition of Windows 11 you want (Pro, Home, etc.).

Accept the license terms and continue.
🔧 Step 6: Choose “Custom: Install Windows Only (Advanced)”
This step is crucial for a complete wipe.

When prompted with installation options, select:

When done, you’ll have one line that says Unallocated Space.
-
Select it and click Next.
Windows Setup will now create the necessary partitions and start installing a fresh copy of Windows 11.
⚡ Step 7: Let Windows 11 Install
This part is mostly automatic.
Your PC will:
