@Adit Sen, I don't understand why you gave 3.5 GB for Linux!! You know very well
that Linux needs 7 or 8 GB for root & atleast 500 MB for swap. If you are using Linux
as primary O.S better give root ('/')15 GB & for swap 1.5 GB. Regarding resizing
partitions in Ubuntu, there's a package available called 'qtparted'. It's similar to
Partition Magic. You can create, move, resize, delete partitions with it. Caution:
Resizing the partition may cause loss of data & may also do a bit of
damage to Ubuntu O.S!!
To install 'qtparted' package, open the Terminal Window & type:
$ sudo apt-get install qtparted
