I want to reinstall my windows 10 including inbuilt MS office 365 in already installed hard disk to SSD which will be a separate drive for windows 10 to booting the system.

Reinstalling is going to be difficult if not impossible.  While you should be able to make HP Recovery Media using the Cloud tool to reinstall Windows, that does NOT include MS Office products.  So even if that works (which it likely will NOT) you will not get MS Office back.

It's likely NOT to work because the recovery tool expects a drive with capacity similar to the original HDD, and if the SSD is a lot smaller (which they usually are) it will fail trying to recreate and repopulate the original drive partitions.

What is a BETTER choice is to Migrate the current setup, including Windows and MS Office, to the SSD.  That way, you won't lose anything in the process.

What I recommend is the following:
1) Download and install Macrium Reflect (MR) from here: https://www.macrium.com/reflectfree
2) Connect the new drive to the PC using a USB-to-SSD drive adapter (like the one illustrated below)
3) Follow the instructions in this link: http://knowledgebase.macrium.com/display/KNOW/Cloning+a+disk
4) Shutdown the PC when done
5) Swap the drives and reboot the PC.

NOTE: To do this easily, the SDD has to be the same capacity as the HDD.  IF you get an SDD that is a lot smaller, then before you do the cloning, you have to shrink the largest partition on the HDD (usually the OS partition), to the size such that it, and the other partitions, fit easily on the SSD.

You should boot from the new drive without any problems.

Typical USB-to-SSD adapter:

Good Luck
