You want to install Windows 10 , but you do not have the installation DVD, or your computer does not have a DVD player. There is always a solution . Microsoft offers a new way to easily create a USB installation key for its OS. Follow these steps to install Windows 10 from a USB flash drive:

How to Install Windows 10 From USB Method 1

We will see how to install Windows 10 after making the assembly of his computere. To install Windows 10, there are two possibilities: to have the installation CD or to install Windows with a USB key .

Install Windows 10 From USB

Step 1: Create a Bootable USB Key for Windows 10

The first step is the preparation of a bootable USB key that will contain the Windows 10 installation files. There are several ways to create a Bootbale USB key for Windows 10 installation:

Method 1 : Using the Microsoft Tool

To create a bootable USB key with the Microsoft tool:

1 – Download the tool for creating Windows 10 installation media via this link:

2 – After running the tool, these two options are available to you:

  • Upgrade the computer now
  • Create an installation media for another PC.

So you will choose, the second option.

3 – In this step you are asked to select the language and version of Windows (if you want to install Windows 10 on this same PC, it is better to check the option ”  use the recommended options for this PC  “)

4 – You now have two choices:

  1. To transfer Windows 10 to a USB stick, you must choose the option ”  USB flash drive  ” and you click on ”  next  ” (you need a USB flash drive with a capacity of at least 4 GB connected to your computer), and as soon as the bootable key creation process finishes, you can start using it.
  2. Or download the Windows 10 ISO file to your computer, burn to a DVD, or use to create a bootable USB key.

The first option is much easier because you do not need to burn the DVD or install any other software to create the bootable USB key. However, if you choose the second option, I invite you to adopt the following method that will explain the creation of a Windows 10 installation USB key from an ISO file.

Method 2 : Prepare a Bootable USB Key From Windows 10 From an ISO image

To follow this method, you will need a Windows 10 ISO file (available in this link ), software to read .iso files like PowerISO and a USB stick:

1 – Format the USB key

2 – Download and install Daemon Tools or PowerISO to extract the files from the ISO image.

3 – Open the ISO image of Windows 10 and copy all its contents into the USB key

At the end of the copy, your USB key will be ready for use.

Method 3: Create a Windows 10 UEFI Setup USB Key

If your computer uses a UEFI firmware interface  , you need to prepare a Windows 10 installation USB stick that is compatible with UEFI mode. The Rufus software will serve us to do this:

1 – Download  Rufus (a portable version is available)

2 – Insert the USB key then run the file rufus-2.11p.exe that you have just downloaded.

3 – Now select the USB key (1), select the option ”  GPT partition type for UEFI  ” (2), check the box ”  Create boot disk  ” and choose ”  ISO-image  ” from the list (3) then, click the CD-ROM icon, and specify the Windows 10 (4) ISO file.

At the end, click on ”  Start  ” then confirm with ”  OK  ” and wait for the transfer of the files to the USB key.

The creation of your Windows 10 installation USB key begins

Wait until Rufus displays READY.

Step 2: Install Windows 10 from the USB key

This procedure decrypts the installation of Windows 10 from a USB key, knowing that it is a clean installation, so remember to save your data before you start  :

Here are the steps:

1 – Start your computer from the USB stick you just prepared. Then, you will see this message ” Press a key to boot from USB ” which I invite you to run and wait while loading the installer.

2 -In the first window, you will be prompted to choose the language, time format and keyboard, then click ”  Next  “.

3 – Click the ”  Install Now  ” button to start the installation.

4 -Now, you must enter the activation key of Windows 10. If your computer has previously worked with Windows 10 (that is, you have already migrated to Windows 10 for free), click ”  ignore  “.

5 – Accept the terms of the license agreement. Check the box and click ”  Next  “.

6 – This is a fundamental step where you have to pay attention. Since it’s a clean installation, you select the ” customize  ” option

7 – After selecting a custom installation, you will see this window which displays the hard drives installed in your computer with their partitions. You select the partition you want to install Windows 10. Be careful to select the correct partition because all the data will be overwritten .

8 – When you click ”  next  “, the Windows installation starts and takes a few minutes to copy the Windows 10 files.

9 – After several starts, you arrive at the customization phase of Windows 10. Here you can choose the recommended settings but for reasons of privacy protection, it is recommended to click on ”  Customization settings  ” and then disable the options useless.

10 – You are prompted to create an account for this PC.

And that’s it, Hello Windows 10

How to Install Windows 10 From USB Method 2

Many PCs no longer have a CD player / burner or I noticed that many users had lost their installation disc, so we will see how to install Windows 10 with a bootable USB stick. The only drawback of the USB installation is that you must already have a Windows computer, otherwise you will need an installation disk.

For the installation you will need a USB 2.0 key . Attention, I emphasize this, the installation will not work if you try to do it with a USB 3.0.

Step 1: Download the Windows 10 USB Key Creation Tool

Installing Windows 10 is a fairly easy process that Microsoft has greatly simplified with the help of an online downloadable tool .

Step 2: Create the bootable key using Microsoft Media Creation Software

Launch the software you just downloaded.

The software offers “What do you want to do? And you have the choice between two options:

  • Upgrade this PC now
  • Create an installation media for another PC

Select the second option and click Next.

You can then choose the language, the version of Windows 10 and the 32-bit or 64-bit architecture. Choose the 64-bit architecture and the edition that’s right for you.

In the next step, the software asks you to choose the media to use and you have the choice between “USB flash drive” or “ISO file”. Select “USB Flash Disk” and click Next.

You will then need to connect your USB 2.0 stick to the computer and select the USB key in the next step of the software. If the key does not appear, it is probably that the USB key is not in 2.0.

Step 3: Wait for the program to download the Windows 10 installation files

The Windows 10 installer will download all the necessary files and install them on your USB key. Wait for a message to tell you that the USB memory stick is ready, then go to the next step.

Step 4: Install Windows 10 on the new PC

Unplug the USB flash drive and plug it into a USB 2.0 port on your new computer. The ports 3.0 are easy to recognize, these are the blue ports, so avoid these at first because they are not functional during the first installation.

Start the PC and go to the “Boot menu” to choose the drive to boot from. Select the USB key and confirm.

Follow the Windows installation instructions, select the hard drive on which you want to install windows and everything should work perfectly!
