You will have to do two things.

First, you will have to use a working PC to create boot media.  

Macrium Reflect is a free tool that can be used to image and restore PCs, but it also has an option to create Rescue Media (in disk or USB form) that can then be used to bot and/or Repair your PC.

It is available from here: http://www.macrium.com/reflectfree.aspx

What I recommend is the following:
a) Download and install Macrium Reflect (MR)
b) Use the option to create a boot USB stick or CD
c) Boot your PC from the MR media -- it will take a while, so be patient!

Second, you will have to check with MiniTool Partition Wizard and EaseUS sites to see if they have a free product you can download that can be used to restore the lost partitions. IF they do, you don't need the boot media from the first section above; instead, you can create boot media using their product and then use that tor restore the lost partitions.

Can I recover the lost data?

@Soudeep 

Data recovery is different from partition recovery -- which is it that you want to do?
