Invalid Partition Table Disk Error: Causes & How To Fix

The invalid partition table error is not a standard disk error. However, you may face a black screen on your computer. It may happen after an attempt to install Windows 10 on an SSD. First, let’s establish what a partition table is.

The Partition Table describes the partitions on that disk. The operating system maintains it on the disk to describe the partitions on it. 

Errors on the partition table can occur due to:

• Outdated BIOS version.
• Corrupted Master Boot Record (MBR).
• Bad sectors.
• Wrong boot sequence.

MBR keeps hard drive information to locate system partitions, logical volume, etc. It can get corrupted when the user doesn’t shoot the system down correctly.

When the boot sequence is wrong or disordered, it leads to an unsuccessful booting process.

The data stored on hard drive bad sectors won’t load during system startup or be read properly.

Symptoms of invalid partition table error

The partition table tells the computer where each section of the hard disk is located. If this table becomes corrupt, it can cause problems when accessing data on the hard disk.

The main sign of a corrupted partition table is the error message “Disk Error invalid partition table” when starting your computer. The message can also be:

• Bad Disk
• Invalid Disk
• Disk Error

One more sign is that your computer may not ‌start up properly.
