Lost Partitions While Upgrading from Windows 7 to Windows 8

Author : Creative Team Updated on February 7, 2017

Installing Windows on a clean hard drive is not at all a problem, as it contains no data and the odds for situations like data loss or corruption cannot come across. In contrast, partitioning a hard drive that contains data might cause weird situations like data loss or corruption. For instance, inefficient repartitioning might cause corruption in one or more existing partitions and eventually cause corruption in those partitions. Well, lost or inaccessible partitions can be recovered using Stellar Phoenix partition recovery software. However, taking precautionary measures is a wise as well as a productive decision.

Hard Drive Partitioning

Hard drive partitioning results in multiple partitions of equal or unequal sizes where each partition acts as a separate drive connected to the computer. Based on the types of data you have for storage, you can create multiple partitions on the hard drive, which also facilitates you multi-boot your computer, i.e. installing more than one operating system in separate partitions or single hard drive.

Efficient Partitioning

Partitioning a hard drive efficiently means creating the required number of partitions without affecting the data stored on the hard drive. An efficient and reliable partition manager is the prime requirement to succeed in drive partitioning. Since Windows does not allow resizing partitions if you create them once, the only option you have to create multiple partitions is during Windows installation.

You can split one partition into two or more other partitions from Disk Management (i.e. a system utility), but it requires you to be experienced to get the job done successfully. Otherwise, it may cause partition loss.

Note: Before deleting a partition to create multiple ones using ‘Disk Management’ utility, make sure the partition contains no data.

Inefficient Partitioning

Inefficient partitioning refers to a state of data loss or missing partition(s) either due to lack of experience or because of an unreliable partition manager used for the task. Besides, a corrupt Disk Management tool might also be responsible for a state of data loss.

Suppose you are installing Windows 8 on your computer having Windows 7 currently installed on it. For a clean OS install, you delete and recreate the primary partition from the installation screen in the boot menu. However, your computer fails to show the primary and a secondary partition that contained crucial files. In such a state, you cannot carry on with Windows 7 installation. Moreover, this leaves your computer in a state of inaccessibility and you eventually fail to access your data stored in other secondary partitions.

Steps to Recover Lost Partition

While installing Windows 8 on a brand new hard drive, you can split the hard drive into several partitions, based on your requirements. However, you must be careful when the hard drive contains data, as your carelessness might cause corruption or loss of one or more partitions containing data. In such a scenario, Stellar Phoenix partition recovery software enables you recover lost partition keeping the data intact. Go on with the following steps to recover lost partitions:
