If you choose to buy system system unit without operating system you might want to understand and learn how to install OS.

The video your about to watch is all about reformatting personal computer with clean OS and clean install.

Let's watch the video:

Format and clean install windows 10 in this step by step tutorial. 

The Windows 10 upgrade process drags old files, settings, and programs from your previous Windows system to your new one. If you want a completely fresh system, though, you have a couple options.

This is particularly useful if you’ve purchased a new Windows 10 PC and it includes manufacturer-installed bloatware you don’t want. Or, you may need to perform a clean install on a computer without an existing Windows system after installing a new hard drive. Of course, you’ll miss out on the good pre-installed apps, like the free DVD player program that comes with many PCs. 

Previously, Microsoft forced users to upgrade to Windows 10 before they could start fresh and do a clean install–which was annoyingly complicated and time-consuming. Now, things are much easier, since you can activate Windows 10 with a Windows 7, 8, or 8.1 key.

The classic method of performing a clean install is still our go-to option with Windows 10. You just need to download and create installation media, either on a DVD or a flash drive, and install it from there.

Download the Windows 10 media creation tool from Microsoft. This tool will download the correct Windows 10 installation files for your system, and help you create an installation DVD or flash drive. Start it up and select the “Create installation media for another PC” option to create installation media.

Be sure to select the correct type of installation media for the copy of Windows 10 that’s licensed for your PC — Windows 10 Home or Professional. (If “Windows 10” is the only option, you can safely use that and it will detect what version you want.) You should also choose your language and select whether you want the 32-bit or 64-bit version of Windows here. Most people will want the 64-bit version, but you can create installation media that includes both, and the installer will automatically select the most appropriate one when you use it to install Windows on a computer.

Install Windows 10 from the installation media like you would any other operating system. Restart your computer with the USB drive or DVD inserted, and boot from that device. This may require you change a setting in the BIOS, access a boot menu, or use the “Use a device” option in the advanced startup options on a modern Windows 8 or 10 device that includes UEFI firmware instead of the traditional BIOS. Select “Install Now” once the Windows installer starts.

Next, you’ll see the activation screen. What you do here depends on your situation:

If you’ve never installed and activated Windows 10 on this computer before, you’ll see the activation screen. Enter your Windows 10 key here. If you don’t have one, but you have a valid 7, 8, or 8.1 key, enter it here instead.

If you’ve ever installed and activated Windows 10 on this computer before, click “I don’t have a product key”. Windows will automatically activate once it’s installed.

The second situation works because of how Windows 10 activates PCs. When you install and activate Windows 10 on a system for the first time, the installer confirms that you have a “genuine Windows” system installed and registers your hardware with Microsoft’s servers. After that, you shouldn’t have to enter that key again on the same PC–Microsoft will recognize your hardware the next time you install Windows 10 on that machine, confirm it’s registered, and automatically activate itself.

Go through the setup process normally until you see the “Which type of installation do you want?” screen. Select the “Custom” option to ensure you’re performing a clean install and not an upgrade install.

Partition your system drive however you like. If you just have a single Windows partition, you can tell the installer to overwrite it. If you have many partitions, you could delete them all and tell Windows 10 to install itself in the unallocated space.

After you log into your new, cleanly installed Windows 10 system, it should automatically activate itself after you connect to the Internet.

To ensure it activated correctly, open the Start menu and click on Settings. click the Update & Security button, and go to the “Activation” tab.
