Cause of 'The Selected Disk Has an MBR Partition Table'

The error message itself has already given you the reason why Windows cannot be installed on the MBR disk. That's because your computer has an EFI system, which is not compatible with an MBR disk. It means your computer's hardware doesn't allow you to boot from a disk with the MBR partition table. However, many users are confused about what the MBR partition table is, what an EFI system is, and why Windows can't be installed on an MBR disk on an EFI system. Here are the answers.

What is an MBR Partition Table

The partition table decides the layout of the hard drives, like an HDD or SSD, and tells Windows how to access the data on it. MBR partition table is a traditional partitioning method that supports disks with a maximum size of 2TB. Besides, MBR has a limit that you can create at most four primary partitions on an MBR disk.

Contrary to MBR, the GPT partition table is a newer standard for disk partitioning. GPT supports disks larger than 2TB and has theoretically no limit on how many partitions you can create on the disk.

Both MBR and GPT are frequently used partition styles on computers. For more information, refer to the article about MBR vs GPT.

What is EFI

Most computers use either the boot modes BIOS or UEFI (Unified Extensible Firmware Interface). The EFI, Extensible Firmware Interface, is the name of the partition that stores the UEFI boot files.

Why Cannot Windows Be Installed to the MBR Disk

MBR disks use the standard BIOS partition table, and GPT disks apply UEFI. That means if your computer has the traditional BIOS firmware, you should install Windows on an MBR disk. Similarly, if the computer is UEFI-based, you can only install Windows on a GPT disk.

You are now clear about why the prompt says, 'Windows cannot be installed on this disk. The selected disk has an MBR partition table.' appears. That's because you are trying to install Windows on an MBR disk on a computer that has UEFI firmware, which is incompatible.

Conclusion

The only solution to 'Windows cannot be installed to this disk MBR' is to change MBR to GPT. To get it done, you can either use the partition tool - EaseUS Partition Master or Windows installation DVD/USB, depending on whether you want to keep the files on the MBR disk. Hope this article can help you solve the problem successfully.

FAQs About Windows Can't Be Installed to This Disk MBR

There are some hot issues related to the MBR disk you may be interested in. Check them below to get more details.

1. How do I change MBR to GPT?

If the computer can boot properly, you can change the MBR to GPT via Disk Management. If your computer cannot boot, you can use EaseUS Partition Master or Windows installation media to convert MBR to GPT.

2. How do I get rid of the MBR partition table?

The partition table is necessary to use a disk. Thus, you cannot simply get rid of the MBR partition style. Instead, you should convert it to GPT if you don't want it.

3. Can Windows 10 be installed on an MBR partition?

Whether you can install Windows on MBR or not depends on the computer's firmware. You can install Windows 10 on an MBR partition if the computer is BIOS-based or UEFI-based with BIOS-compatibility.

4. Can Windows 11 be installed on MBR disk?

No! Actually, Windows 11 requires secure boot mode which only works on UEFI boot mode, and as UEFI boot requires GPT disk type, you'll need to convert the OS drive into GPT before installing or upgrading to Windows 11.
