Question about partitioning on dual boot systems (Windows/Linux)
 

I have a doubt in this, if there are 3 partitions in Windows, how to select the right partition to install the Linux? How to partition it? If i want to allocate space from C drive itself is it right method to do it?

The easiest way is to shrink a partition or remove an unused partition, so that you get free, unpartitioned space on the disk (the Windows partition manager can do that), then let the installer use the free space to create the needed partitions automatically. It may be possible that you have already 4 primary partitions on the disk (many laptops come in that configuration), which will prevent the installer from creating new partitions if you don't remove one. We will know that if you post the the partition layout. You can get the exact layout with running from a Linux live-medium.

It is extremely easy to partition windows. The first partition is probably System Reserved, the second C:, the third a recovery. I would shrink C. Simply download and burn a iso to a cd, or activate it to a flash drive. Restart the machine, open BIOS settings and run the iso. Let it boot. If you are using a LIVE iso, there will be a partition manager available. Simply go through the steps and shrink C:, the second partition, (sda2), and make a new linux ext4 there. You may need swap as well. You can "install alongside windows" to take care of these steps for you. Reserve at minumum 5gb for linux, but recommended 20gb. Simple as that!
