Invalid Partition Table Is What Error and How to Fix It

This guide explains how to resolve Invalid Partition Table Is What Error and How to Fix It, starting with the most likely causes and moving through practical troubleshooting steps.

The most common cause of this error is a corrupted partition table. It is in the MBR (Master Boot Record) of the boot sector, which contains information about how to partition logical, containing file systems, organized on that medium. The most common cause of the error is a hard drive failure or a write error.

There is also another cause: Of all the available partitions on the hard drive, only one is set to be the boot partition. If MBR detects two active partitions on the current disk, the system loading will stop. This is usually caused by errors made while configuring partitions manually.

And here are some measures to fix the above error.

Method 1: Change the boot sequence to the hard drive

If your computer is attached from 2 or more hard drives, the Invalid Partition Table error will occur because the computer boots up incorrectly on a hard drive that does not contain windows. In this case, you can restart your computer. Then, access the BIOS and install to put the hard drive containing the Supported operating systems first on the list of hard drives in the computer, then it will prioritize booting into the hard drive with the Supported operating systems. Finally, restart the computer to see if the Windows system can boot normally.

Method 2 : Upgrade the BIOS version

When you install Windows 10 on an outdated SSD and BOIS drive, it can lead to the Invalid Partition Table error. In this case, you need to upgrade the BIOS to the latest version. Download the latest BIOS from the computer manufacturer's website you're using, but because you can't boot into the system, you'll need to use a different computer to create a USB boot after that. Copy the latest BIOS version to the USB flash drive and proceed with the installation on the defective computer. The steps are as follows:

1. Connect the USB to another computer
2. Visit the manufacturer's website and download the latest BIOS version
3. Copy the BIOS setup file to the USB
4. The USB connection containing the BIOS setup file to the computer has a problem.
5. Boot your computer, press F12 on Startup to open Menu boots .
6. Select boot into USB that you have connected.
7. If the BIOS. exe file does not run automatically, you need to type the E: XXXXXX. exe command prompt (where E is the name of the USB drive letter and XXXXXX is the name of the file you saved to the USB drive).
8. Press Enter to run the file and install the BIOS.

Once the BIOS update is complete, continue your installation of the Supported operating systems and check for errors.

Method 3: Repair corrupted MBR with CMD command

To do this, you need a USB or Windows 7/8/10 installation disc, the steps are as follows:

1. Insert the USB flash drive or disc into the computer

2. Restart your computer and choose to boot into USB or Windows installation disc

3. Click Repair your computer

4. At the System Recovery Options screen, select Command Prompt

5. Run the following commands:

bootrec / fixboot bootrec / scanos bootrec / fixmbr bootrec / rebuildbcd 

Press Enter after each command and wait for the commands to finish

6. Restart your computer and check for errors.

Method 4: Check the status of partitions with Diskpart

The integrated Windows Diskpart utility can be used to check the status of partitions and mark them inactive if necessary. To do this you also need a USB or windows installation disc.

Here are the steps to run Diskpart and change the status of the disk:

1. Boot from the Windows installation disc
2. Click Repair your computer after selecting the appropriate language, time and keyboard
3. Select the Windows installation drive, usually C:, and click Next
4. Select Command Prompt when the System Recovery Options window appears
5. Type the diskpart command and press Enter.
6. Then enter the list volume command and press "Enter" to check the active partitions. If it is an active partition, it will have a "*" next to its name.
