How to Fix ‘The Selected Disk Has an MBR Partition Table’ Error: It is possible that you will frequently encounter a frustrating error that will prevent you from successfully installing the Windows operating system on your personal computer. This error may prevent you from installing the system. The message that appears on the screen could read, “Windows cannot be installed to this disk.”

An MBR partition table is present on the disk that was selected. The error that states “the selected disk has an MBR partition table” is extremely common and can be found on a variety of Windows installation versions. It has been reported by a few users that the process of installing Windows OS on their hard disk is interrupted whenever they attempt to do so.

As soon as they press the Install now button during the Windows Setup process, the Windows installation fails, and Windows Setup displays the message that Windows cannot be installed to this disk. Instead, the selected disk displays an MBR partition table error. In the event that you are also experiencing this issue, there are a few potential solutions how to Fix ‘The Selected Disk Has an MBR Partition Table’ Error.

Causes of the ‘The Selected Disk Has an MBR Partition Table’ Error

1. Mismatch between partition table type and installation tool: If you’re using an installation tool or partitioning software that expects a GPT partition table, but the disk you’re working with has an MBR partition table, you’ll encounter this error.
2. Attempting to install a UEFI-based operating system: Modern UEFI (Unified Extensible Firmware Interface) based systems often require a GPT partition table for booting. If you’re trying to install an operating system that requires UEFI boot mode, but your disk is using an MBR partition table, you’ll see this error.
3. Legacy hardware or software limitations: Some older hardware or software may not support GPT partitioning, necessitating the use of MBR partition tables. In such cases, attempting to install an operating system or create partitions using GPT may result in this error.
4. Disk previously used with MBR partitioning: If the disk was previously used with an MBR partition table and not properly converted to GPT before attempting a GPT-based installation or partitioning, you’ll encounter this error.
5. BIOS settings: Incorrect BIOS settings can sometimes cause this error. For example, if your BIOS is set to Legacy mode instead of UEFI mode, and you’re trying to install an operating system that requires GPT, you may encounter this error.
