Actual changes to your hard disk are executed by  the program only if you confirm with [Enter], [Y], and  ‘OK’. With the option labeled ‘Proceed’, an analysis first  takes place. The present status can and should be saved using  the ‘Save’ button.

TestDisk shows  the hard disk  info as CHS (Cylinders, Heads, Sectors) after a verification started with ‘Search’. This is  followed by  its  total size  in MB. What is  important  is  the first character of the output  line: ‘*’ means primary and active as boot partition, ‘P’  is primary but not bootable, ‘L’  is a logical drive, and ‘D’  indicates  the partition has been deleted. Selected the deleted partition, place  it on  ‘P’ using  the  right/left-arrow keys and save with  ‘Write’.
