Partition for my notebook

How can i get partition in my new hp pavilion 6115tx?
I have already 4 primary partition named as C, system, recovery, HP_TOOLS.
i cant make another partition.

4 is the maximum number of Primary partitions allowed. You must change one to an extended partition. In the extended partition, you can create as many logical drives as the letters will allow.

You may want to find out what in 'ell HP Tools is and decide if you want to get rid of it. Find out if it is relevent to the warranty and what not.

how can i make extended partition?

Go to the Start Orb and in the command line type "cmd" then right-click on the selection above and choose to "Run as administrator".

Do the following in the "cmd" window with administrator privileges:

Use the diskpart utility in an elevated command prompt window. The commands will look something like this:

C:\Users\yourname> diskpart

DISKPART> select disk 0
DISKPART> create partition extended
DISKPART> create partition logical

For help on a command, type its name in the help command. For example:

DISKPART> help create partition
DISKPART> help create partition logical

----------------------------------------------------------------------------------------------------------------------------
Then type exit, it make take two times to exit to get completely out of the "cmd" window.
