Understanding the GPT Disk Format

Before we dive into the solutions, let's establish what GPT, or GUID Partition Table, means. GPT is a modern disk partitioning scheme that has replaced the older MBR (Master Boot Record) in recent years. It offers numerous advantages, including support for larger disk capacities and more robust data structures.

Common Causes of the Error

Understanding the root causes of the ‘Windows can be installed only in GPT disks' error is crucial. Common culprits include incorrect disk formatting and BIOS settings. By identifying these factors, you can better address the issue.

Check Your Current Disk Format

To begin resolving the error, you'll first need to determine your current disk format. Knowing whether your disk is in GPT or MBR format is essential for selecting the appropriate solution.

Converting Your Disk to GPT

One of the primary solutions to the error is converting your disk to the GPT format. We'll guide you through this process step by step, using the Disk Management tool in Windows. Remember, before proceeding with any changes, it's imperative to back up your data to prevent any data loss.

Alternative Method: Converting Disk to GPT Using Command Prompt

For those seeking an alternative approach or facing difficulties with Disk Management, Command Prompt can be a powerful tool. We'll walk you through the commands and steps required to convert your disk to GPT using this method.

To get started:

  1. Access the Command Prompt during the Windows installation process by pressing Shift + F10 simultaneously when you see the error message.
  2. In the Command Prompt window, type ‘diskpart‘ and press Enter.
  3. Next, type ‘list disk‘ to display all connected disks.
  4. Identify the target disk and note the disk number.
  5. Type ‘select disk X‘ (replace ‘X' with the actual disk number) and press Enter.
  6. Type ‘clean' to erase all data on the selected disk.
  7. After cleaning, type ‘convert gpt‘ to convert the disk to the GPT format.
  8. Close the Command Prompt and proceed with Windows installation.

This method is effective, but demands caution, particularly when using the ‘clean‘ command, as it erases all data on the selected disk.

Adjusting BIOS/UEFI Settings

Incorrect BIOS or UEFI settings can also trigger the ‘Windows can be installed only in GPT disks' error. We'll explain the significance of these settings and guide you on how to access and modify them to ensure a smooth installation.

To access your BIOS (Basic Input/Output System) or its modern counterpart or UEFI (Unified Extensible Firmware Interface), you'll typically need to press a specific key during the initial boot-up sequence, such as F2, F12, Delete, or Esc, depending on your computer's manufacturer. Once inside, you'll be presented with a range of options and menus, each governing a different aspect of your system's behavior.

Choosing Between Clean Install and Repair

When dealing with this error, you'll face a critical decision: should you perform a clean Windows installation or attempt to repair the existing one? We'll compare the pros and cons of both options to help you make an informed choice.

Troubleshooting with Command Prompt

In addition to the disk conversion methods, we'll provide you with a list of useful Command Prompt commands for troubleshooting the error. These commands can help resolve common issues and get your Windows installation back on track.

Seeking Professional Help

While the solutions we've discussed are effective for many users, there are cases where professional assistance may be necessary. We'll outline scenarios where DIY methods may fall short and advise on when to seek expert help.
