Reason for the Error

The error “Invalid Partition Table” while starting or installing the Windows 10 usually appears due to the following reasons:

Boot sequence plays an essential part while booting the system. When the boot sequence is in disarray, it will lead to an unsuccessful booting process. So you should always make sure that the boot order is properly set through the boot menu.

In many cases, the reason for this error is a corrupted partition table. This is in the Master Boot Record (MBR) of the boot sector. The MBR contains information about logical volume, location of system partition, etc. on your hard drive.

3. When There Are Two Or More Partitions Active On Your Hard Drive
