So, the fourth partition is an extended partition divided into logical

As per the documentation if you want to use GPT, you need to use EFI.

Easy BCD is a proprietary product, and since you are paying for it,

Why do you want to do that?

If you are in Chennai, I'd suggest you bring your laptop to the
monthly meet-up so that we can take a look at it, and also clarify
your doubts.

I don't think there is enough free disk space to install Ubuntu on this machine.

Do these show up when you install Ubuntu?

Check in the UI or in fdisk output when you boot from the Live CD.

The bootloader gets installed in the first 512 bytes and is called the

If you have run out of primary partitions, waiting for Ubuntu 16.04 is
not going to solve anything. Please check your primary partitions.

Good suggestion but ...

I suggest that OP report the output from a Live Boot session.  It will
give a priori information about how the disks are partitioned by the
vendor for the OEM OS.

Not sure how new your laptop is i.e. chipset.   Suggest you try 15.10.

I have installed 15.10 on a newer Dell laptop (last summer) and things
installed w/o any issues.  I did not have to tinker with drivers; all
devices (including keyboard back light, touch screen) are working out
of the box!  I plan to upgrade the OS when 16.04.1 LTS is released by
summer 2016.
