The 'Fix The Selected Disk is of the GPT Partition Style' error occurs when you try to install Windows 7 on a disk that uses the GPT (Globally Unique Identifier) partition style. This error affects users who are trying to dual-boot Windows 7 with Ubuntu or other Linux distributions on Lenovo laptops, including the Lenovo G510.

This error can be frustrating as it prevents the installation of Windows 7 and may lead to data loss if not addressed properly. However, by following the steps outlined in this guide, you should be able to resolve the issue without losing any data.

💡 Why You Are Getting This Error

  • The GPT partition style is used on newer hard drives and solid-state drives (SSDs), which are commonly found in modern laptops like the Lenovo G510. Windows 7 does not support GPT disks, so if you try to install it on a disk with this partition style, you will receive the 'Fix The Selected Disk is of the GPT Partition Style' error.
  • Another possible cause could be that the disk has been previously used as a GPT disk in another operating system, such as Linux. In this case, Windows 7 may not recognize the disk's format and will display the same error message.

🚀 How to Resolve This Issue

Using a Bootable USB Drive to Reformat the Disk

  1. Step 1: Create a bootable USB drive using a tool like Rufus or UNetbootin. This will allow you to access the disk's format and make any necessary changes.
  2. Step 2: Insert the bootable USB drive into your laptop and restart it. The USB drive should be recognized as the first boot device, allowing you to enter the BIOS settings.
  3. Step 3: In the BIOS settings, set the disk with the GPT partition style as the primary boot device. Save the changes and exit the BIOS settings.

Using a Different Disk or Partition

  1. Step 1: Check if you have another disk or partition that uses the MBR (Master Boot Record) format, which is compatible with Windows 7. If available, use this disk instead of the one with the GPT partition style.
  2. Step 2: If no other disk is available, try creating a new primary partition on the existing disk and then install Windows 7 on that partition.

🎯 Final Words

By following these steps, you should be able to resolve the 'Fix The Selected Disk is of the GPT Partition Style' error and successfully install Windows 7 as a dual-boot operating system with Ubuntu 14.04 on your Lenovo G510 laptop.
