How to Install Windows 11 from a Disk Image (ISO) File

Are you excited about the latest release of Windows 11? Before installing it, make sure your computer meets the minimum requirements and that you have a valid ISO file. Here's a step-by-step guide on how to install Windows 11 from a disk image (ISO) file.

Converting Your Drive to GPT

Before changing your firmware mode from BIOS to UEFI, you need to convert your drive using a GPT partition. This is because Microsoft requires that Windows 11 users use the GPT partition scheme, which allows for disk drives bigger than 2TB.

To do this, follow these steps:

1. Open Command Prompt as an administrator.

2. Type `mbr2gpt /convert` and press Enter.

3. Then, type `mbr2gpt /validate` and press Enter.

4. Sign in with your administrator account.

5. Click Troubleshoot on the next options screen.

Changing Your Firmware Mode to UEFI

Once you have converted your drive to GPT, you can change your firmware mode from BIOS to UEFI. To do this:

1. Restart your computer and enter the BIOS settings.

2. Look for the 'Boot Order' or 'Priority Boot Device' setting and set it to UEFI.

3. Save your changes and exit the BIOS settings.

Installing Windows 11

Now that you have converted your drive to GPT and changed your firmware mode to UEFI, you can install Windows 11 from the ISO file. Here's how:

1. Download the Windows 11 ISO file from the official download page.

2. Double-click on the `setup.exe` file to begin the installation process.

3. Choose Windows Explorer as the program and click Apply.

4. Select Properties from the drop-down menu, find the ISO file you downloaded, right-click on it, and select Mount.

Mounting the ISO File

Once you have mounted the ISO file, you can install Windows 11 directly from it without using a DVD or USB flash drive. Here's how:

1. Open File Explorer and navigate to the mounted ISO file.

2. Double-click on the `setup.exe` file to begin the installation process.

Installing Windows 11 from a disk image (ISO) file is a straightforward process that requires some technical knowledge. By following these steps, you can successfully install Windows 11 on your computer and enjoy all its new features and improvements.

Remember to refer to the PC Health Check app before attempting to install Windows 11 to ensure that your PC meets the minimum requirements.
