Showing Low Disk Space on "Filesystem root" 2 GB free space

Please help, i have installed parrot on 200 GB unallocated space on dual boot with windiws. but after finishing the installations i sew this warning Low Disk Space on “Filesystem root” and says only 2GB space free.

Did you give enough space to your / partition?
(Note: not same as /root folder)?

Sometimes people make the mistake of giving plenty of space to /home, not saving enough side for /

What does df command return?
