i dont know how to explain this but i have a 500gb drive divided as 
PARTITION 1
262gb  = ntfs. this is where windows resides.
EXTENDED PARTITION 
PARTITION 2
238gb 
Filesystem 
Partition 5
130gb = ntfs. this is where windows files reside.
Filesystem 
Partition 6
20gb = ext4. mounted at Filesystem root
Swap Partition 8
2gb = swap

Free space of 8gb= Unallocated space


Filesystem 
Partition 7
85gb = ext4. mounted at /home.

And there is another partition named Free Space Unallocated space that takes up 1.1 gb.

Whats with all these unallocated space. can i retake them as ext4 partitions? how?
