Hi Priyansu,
I am Dave, an Independent Advisor, I will help you with this.
From reading the specs of that laptop, it is not really strong enough to run Widows 10 and you will experience hardware problems and possibly blue screens, because the hardware is now considered to be legacy and you only have 2GB of DDR2 RAM.
If Windows 10 is going to run on that hardware, the version you should try to install is the 32bit version of Windows 10 Home, the 64bit version will not run on that hardware.
