[SOLVED] SSD and HDD dual boot Windows 10 and Windows 7

[shaikyahiya]

I currently have a PC with Windows 7 64 bit installed on an HDD(SATA).
I want to add an SSD(SATA) to it and install Windows 10 on it to be able to have a dual boot PC.

I am not sure how to start. I have never done a dual OS install.
Will just plugging in the SSD and installing Windows 10 via Microsoft's MediaCreationTool help or do I need a bootable USB instead?
A little help would be appreciated. Thanks.

My PC Specifications:
Processor: Intel Core i3 6098p
RAM: 8GB DDR4
GPU: Zotac Nvidia Geforece 1050 Ti 4GB
HDD(SATA): 500GB(with Windows) + 1TB(additional storage)

Going to add:
WD Green 240GB Internal SSD

1) Create Windows 10 installation media on a flash drive using MediaCreationTool.

2) Power down and add SSD and unplug all other drives.

3) Set USB bootable to top of boot order in bios

4) Install windows onto your SSD.

5) Shutdown and plug other drives back in.

Now when you boot you can go into bios and choose which drive (os) to boot from. You may need to use BCD edit to get prompted every time you boot.

You only need to go into the bios to set which drive will be the default drive.
When you want to boot other drive, press the F-key during POST that allows you to override the boot device or select the boot device. Which F-key it is will be displayed at the bottom of the screen at the same time as the option to enter the bios (often the delete key).
