A Windows-based hard drive is mainly divided into two or more partitions. The exact size and location for each partition is saved in a database named 'Partition Table'. This table is saved in the first sector of a hard drive and is 64 bytes long. Corruption in this table can occur due to improper system shutdown, virus infection, and operating system malfunction. In most partition table corruption events, a Windows user confronts an error message that does not permits the system to boot the system. This further results in inaccessibility of all the hard drive partitions and data stored within them. To master such error messages and access all the partitions, it is best to restore them from an up-to-date backup. However, if the user has not maintained any backup, or the backup fails to meet your expectations, then you will need to choose a third-party Partition Recovery utility to recover your partitions.
To elaborate the above scenario, consider a practical case, wherein you encounter any of the below error messages while trying to boot your Windows-based system:
“Not found any Active Partition in hard drive.”
“DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.”
“Invalid partition table.”
“Missing operating system.”
“Boot infection or Boot virus.”
“Invalid media type reading drive.”
After any of the above error message appears, the system becomes unbootable and subsequently the hard drive data also becomes inaccessible.
The root cause for the occurrence of the above error message is corruption in partition table.
To conclude all the above error messages and to access the data saved in the partitions, follow the steps mentioned below:
Execute 'Startup Repair' option to resolve startup issues.
Use 'Last Known Good Configuration' option to boot your system.
In case, both the above options fail to solve the above error messages and the partitions remain inaccessible, then you will need to reinstall the operating system and recreate new partitions. However, while doing so all the previously saved data in the partitions becomes inaccessible. To recover all those partitions and their data, you will need to use a commercial Partition Recovery application. A Partition Recovery Software uses efficient recovery mechanisms to recover lost, deleted, and formatted hard drive partition.
