How to install Windows 10 - Guide


Windows 10 installation is not too complicated if you have good instructions. Of course, you also need to know the computer well enough to be able to follow all the steps.

How long do I need to install Windows 10?

If you are doing this installation for the first time, you will probably need about 2 hours. You will spend most of your time getting to know and preparing your computer, while the installation itself is quite fast and takes about 20-30 minutes, counting the time while you just sit and wait for the automatic part of the process to finish.

What do I need to install Windows 10?

  • Windows ISO file, we will explain where to download Windows 10.
  • USB drive of at least 8 GB to create a bootable USB with Rufus tools
  • Backup data from the computer where you are doing the installation (if you need this data).
  • Ability to access the BIOS setup of your computer.

How to install Windows 10 step by step

Important Note Before You Go: This Windows 10 installation guide will show you the installation procedure on a blank HDD or SSD. If you have data you want to save, follow the instructions carefully, and back up your data. Otherwise, you can lose them permanently.

Step 1: How download windows 10


If you do not have a DVD or USB drive that already has the installation version of Windows on it, you need to download the Windows ISO file from the following link:

Download Windows 10 ISO:

Download Windows 10 

Windows Media Creation Tool

This will start downloading a smaller file program that will download the Windows installation for you and help you with that. Save this file somewhere on your computer:
Download Windows 10 2

Find that file where you saved it and double-click it to start executing the file. Once the file is run, accept the terms of use:
accept the terms of use


Pay attention after that, they will ask you what exactly you want to do (What do you want to do?). Offered:

  • Upgrade this operating system (Upgrade this PC now.)
  • Creating installation media for another computer (Create installation media (USB flash drive, DVD, or ISO file) for another PC)

So, you need another option because that's how we download the installation version of Windows 10 and we can burn it to a DVD or USB drive.

Select this second option and click the Next button:


clean install wndows 10 or upgrade

In this section, if you do not want to change the language and architecture, you can leave it as is and click Next. If you are doing this on one computer and are planning to install it on another, uncheck the Use the recommended options for this PC option:

Now pay attention to what you will choose next. There are two options:

  • USB flash drive (you need a USB drive of at least 8 GB and the installation will be saved directly to that USB)
  • ISO file (you will download the Windows installation as an ISO file and use it later to burn to a DVD or USB drive manually)


iso or usb intallation


A window will open where you need to choose where to save this file, then select a folder and click the Save button:

Now that you have downloaded your windows 10 iso file, we can create your bootable USB.


Step 2:  How to create a bootable USB - Rufus

Installing Windows with a USB drive is faster. For this to work, you need to insert the downloaded Windows ISO file into the USB drive. It is not possible to do the classic copying of a file from a computer to a disk here. It must be done with the help of the tool provided for this procedure. You can use Rufus and you need to download it from the link below: 
Rufus is a tool for creating a bootable USB: Download Rufus
Visit the page and download the latest version of Rufus. Once you download the file, simply double-click on that file and Rufus will be launched (no need to install).

Note the following Rufus features:

  • Device: select the USB you planned to install
  • Boot selection - Select: select the ISO file you downloaded
  • Partition scheme: select GPT
  • Target system: select UEFI (non CSM)

Finally, click Start and wait for the Rufus to complete.

When Rufus notified you that everything is complete, you can proceed to the next step. You now have a USB drive ready with the installation version of Windows 10.


Step 3: Back up important data before Windows installation

The easiest way to back up data is to attach an external drive or larger USB drive to your computer and transfer any important data you want to save before installation. Later, when the installation is complete, you can restore the data you copied to your computer.

Step 4: Enable boot device in BIOS

What are we supposed to do here? When you start your computer, the BIOS starts everything, including the disk from which it reads the data from which the operating system that is installed on the computer's disk is started.

Now, to do the installation of the new operating system, we need to set the BIOS not to boot the existing (old) operating system, but the system that we recorded on the USB drive.

Therefore, you need to adjust the order of the devices that start and put the USB device on which the installation version of Windows is in the first place.

Depending on which BIOS you have, there are two ways to do this. One way is to set the device order in the BIOS (more complicated), the other way is to run the selection manually and thus choose which device to boot (easier).

How to start BIOS setup and set device order?

This depends on the computer model, the motherboard, or the laptop manufacturer. When you start the computer in those first few seconds, you will see that the screen says which key to press to start these settings.

Here's which key is used on the most common computer and motherboard models:
  • ASRock: F2 or DEL
  • ASUS: F2 for all computers, F2 or DEL for motherboards
  • Acer: F2 or DEL
  • Dell: F2 or F12
  • ECS: DEL
  • Gigabyte / Aorus: F2 or DEL
  • HP: F10
  • Laptopa Lenovo: F2 or Fn + F2
  • Lenovo (desktop computers): F1
  • Lenovo (ThinkPad): Enter and then F1.
  • MSI: DEL for motherboards and computers
  • Microsoft Surface Tablets: Press and hold the volume up button.
  • Origin PC: F2
  • Samsung: F2
  • Toshiba: F2
  • Zotac: DEL
If your motherboard or computer model isn't on this list, try finding it on Google or looking for the user guide that came with your computer.

Once the BIOS starts, look for the Boot option. If you have a simpler BIOS as in the image below, under the Boot option you will see the order of the devices. For example, the image below shows the boot order of the device, that is, the order in which the BIOS checks which device the operating system is booting from:
bios boot

The page always describes how to change the order or indicate which device will be the first. All that matters is that you follow the instructions nicely and you will set them up easily.

Since you are installing Windows from a USB drive, the first device needs to be a Removable device. When set, press the F10 button on the keyboard to save the settings. This will restart the computer and immediately after that, the operating system will be booted from the USB drive.

Step 5: Windows 10 installation

You will first see the screen as in the picture below. That's fine, wait for the installation to start.

Now select the language, time format, and keyboard layout. When you have selected what you want, click the button Next:
windows setup language time keyboard

Step 6: Windows 10 activation 

windows install

You can now enter the Windows serial number you purchased, or you can do so later after installation (if you click I don’t have a product key). Whether you enter a serial number or select the option to do so later, click Next to continue:
Windows producy key

Step 7: Choose the version, for home or business

In this step, you need to choose which version of Windows 10 you want to install. In the image below, you can see the choice between the Windows 10 Pro and Home variants. Depending on which installation you have, you may be offered other options.

Choose the one that suits you and then click Next:
windows 10 home or pro

Step 8: Accept the terms of use

Here are the terms of use, tick I accept the license terms and click Next
Accept the terms of use setup

Step 9: Clean install Windows 10

Two options will be offered in this step. One is to do an upgrade, which will only do an upgrade of the operating system and thus save all the files and settings.

Since this is a guide - How to installing Windows 10, we do clean install windows 10. You need to click on another option that reads Custom: Install Windows only (advanced):
Install Windows only advanced

Step 10: Creating a partition for Clean install Windows 10

This is the most important part of the installation

If you have a blank disk on your computer, for example, you bought a new computer or installed a new blank disk on an old computer, this is the image you will see.

The figure, in the table that shows what is on the disk, shows the disk space that is empty and not allocated (Unallocated Space) to a partition, for example. This is to be expected because it is a blank disk:
windows 10 unallocated space - clean install windows 10

Click the New button. New is meant to create a new partition from the space you have available.

If you want the entire disk to be one large partition, everything will be under the C partition. For example, you do not have C and D partitions separately, leave it as it already stands:
windows new partition - clean install windows 10

In case you want to allocate more partitions, to split the disk into several partitions (to have C, D, E ), use the New option to create new partitions from the unallocated space as long as you have space. For example, if you have a 512 GB disk, you can create one partition of about 100 GB, and two of about 200 GB each.
windows 10 creating partition - clean install windows 10

When you create the first partition, a notification appears telling you that an additional partition will be created automatically where Windows places some of its files. All you have to do is click the OK button:

windows partition done - clean install windows 10
If you have decided that you have only one partition on the entire disk that occupies the entire disk, this is the image you should see after creating that one large partition (image below).

You'll see one small partition that Windows created automatically and one large one that you created. To continue with the installation, click on the partition you created and then the Next button.

In case you have created more than one partition, click on the one you plan to be system (C) and then click Next:
windows select partition - clean install windows 10 

Your Clean install Windows 10 has started.

clean install windows 10
Now you just have to wait for Windows to copy all the files to the right place on the disk and install everything.

Step 11: You have completed the Clean install of Windows 10

Your Windows 10 is installed and operational, if you want to set up your Windows to be as fast as possible, the instructions can be found here.
