how to install linux with windows in the same disk

  fedora, linux, windows

I’m a windows user, and I want to install Linux with my windows 10 on the same hard disk.
my HDD has 2Tb so I take 30Gb to install fedora but after making the live USB and go to the installation
I see only one partition that is all the disk (2 Tb ) which means I’m going to lose my windows and all my files enter image description here.

the partition I made is the right 30Gb.
