Overview on recovering data from deleted/lost partition

"Partitions got lost during installing OS! There are two disks on my computer, an SSD and a hard drive. I was reinstalling Windows 7 and the OS was supposed to go to SSD, but I didn't know why it wiped the hard drive. I stopped the process right away when I noted the error. Now the hard drive has no partitions, but it hasn't got reformatted. How can I restore those lost files and partitions from the unbootable computer?"

Disk partitioning process divides disk into one or more storage sections and system assigns a drive letter for each section, and these are partitions C, D, E, etc. on your computer. In general, Windows OS is installed on C drive and personal files are stored on other partitions. Partitions are logical sections on a hard drive, and they can be deleted, created, formatted, resized, hidden, backed up, and so on by disk partition software. If you delete a partition, you are going to get unallocated disk space and lose all files in the partition. Apart from partition deletion, there are many other causes accounting for partitions loss, for example, repartition disk, bad sector, virus, human error, OS reinstallation and more.

What to do when partition gets deleted? First and foremost, you should keep deleted data from being overwritten: do not recreate partition, add unallocated disk space to other partition, copy data to the save drive, etc. Once lost files get overwritten, they will be lost forever. Then use reliable recovery software to scan the disk for lost files and partitions. Now it's time to look at how deleted partition data recovery works.
