Leaving around 90GB of free disk space. Now Iam unable to create new patition with fdisk or by installing the fedora 16.

The DOS partition table only allows 4 primary partitions, one of which 
may be an extended partition. You already have 4 primary partitions 
(sda1-sda4), so the unallocated space between sda3 and sda4 is unusable.
