Lost the data and try to recover it

I read someone wrote how he was lost the data:

When a file is deleted (removed from the recycle bin within Windows), both file systems simply mark the file as deleted. The data is not actually removed from the drive, but rather the space it takes up on the disk is now considered to be free. Consequently, if you delete a file accidentally, you have an excellent chance of being able to restore it provided you do not write more information to the disk.

In my situation, I had two NTFS partitions on the effected disk. When I ran FDISK, it wrote garbage information over certain areas of this disk, including areas of both partitions. As a result, the first partition (the one with my article on it) had lost its partition boot sector, meaning it could not be accessed normally by an operating system. The second partition had merely had crucial system files overwritten, and was unbootable, but still fully accessible once I transferred the disk to another computer.

Thankfully there is a way to fix all of this, and get the data back!
