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

  • The UEFI BIOS (Unified Extensible Firmware Interface) BIOS is used by modern computers instead of the older BIOS. It is more advanced and safer. For booting, UEFI needs discs to use the GUID Partition Table (GPT) method.
  • MBR Partition Table: MBR is an older way to divide up discs that has some problems, like only working with discs up to 2 TB in size. It still works, but it doesn’t work with UEFI boot mode.
  • If your BIOS is set to UEFI mode but the target disc uses MBR, the system won’t see it as a bootable disc, which is what causes the problem.
Fix 'The Selected Disk Has an MBR Partition Table' Error

  2. Find the disc that has the mistake on it.
  3. Pick up the disc and rightclick on it. Then choose “Convert to GPT Disc.”
  4. When asked, confirm the move.

Use DiskPart

  1. Open the Command Prompt as an administrator.
  2. Press Enter after typing diskpart.
  3. To see a list of all the various discs, type list disc.
  4. Pick out the disc that you want to turn.
  5. Type choose disc (use the real disc number instead of ).
  6. To get rid of all the divisions on the disc, type “clean.”
  7. To change the disc to GPT, type convert gpt.
  8. Put away the Command Prompt.

Perform a Clean Installation

  1. Start up from the Windows installation disc.
  2. If you are asked where you want to install Windows, pick the empty spot on the disc (which now has a GPT partition style).

Check Boot Media

Make sure that the file you’re using to install Windows supports UEFI. The installation USB you made with the Windows Media Creation Tool should work with both UEFI and Legacy boot modes.

FAQs

Why can’t i install Windows on MBR partition table?

You already know why Windows can’t be loaded on the MBR disc from the error message. That is because the system in your computer is EFI, and an MBR disc doesn’t work with IT. It means that the hardware in your computer won’t let you start up from a disc that has the MBR partition table.

How do I remove a MBR partition table?

In Windows, you can delete more than one MBR disc at the same time. Either “Delete Volume” in Disc Management or “Clean” in Diskpart can be used to get rid of them. EaseUS Partition Master is a good third-party tool that you can use instead.

Can you convert MBR to GPT without erasing data?

The MBR2GPT.EXE file changes the disk’s partition style from Master Boot Record (MBR) to GUID Partition Table (GPT), but it doesn’t change or delete any data on the disc.
