[CentOS] data recovery

Two weeks ago I've been in similar situation on an 80 gig sata drive.

Found it with 8 partition; boot was there but nothing of the operating 
system to load Linux 5.6

My recovery solution was to put the disk on a window system as a secondary 
drive. Just connected to read data
For reading I found a software called ' nucleus kernel linux'  from 
http://www.nucleustechnologies.com/Linux-Data-Recovery-Software.html

On partition 3 I found nearly all my data files and their directories but 
were missiing  /etc /bin /dev ....

Hope this help.
