Install Windows 10: Make a bootable USB drive

A while ago the installation of Windows on a PC was only done through a CD-Rom, but that time is over. Today a simple USB key does the job very well, the condition? This key must have sufficient capacity to receive the operating system files and then it must be made bootable.

I'm not going to dig any deeper into the terms, but making a USB drive bootable is preparing it to receive an OS (Operating system) so that it is recognized by the computer during startup.

There are a number of techniques to make a USB drive bootable, but in this article I'm going to show you the world's easiest method to make it happen. This method does not require any special software. You will simply need to run your “Command Prompt“Windows.

Here is the article that details step by step how to make a USB drive bootable with the Windows command prompt.

NB: To install Windows 10, your key must have the necessary capacity to contain Windows files. A 4 Giga USB key should suffice.

Saving data

If the computer you are using is the one on which you will need to install another version of Windows, I strongly advise you to back up your data first.

Move existing data to (Office, My documents, Pictures, Music, Videos, Downloads) to another disk. Take them out of the disc C so that they are not exposed to any danger during the operation.

NB: even while using your computer everyday, I advise against always leaving your important data in the system folders. Always favor other partitions of the disk.

Install Windows 10: Beginning of the installation

To start installing Windows 10, make sure you are plugged into AC power or so to have a good autonomy, even if the operation in question does not take much time.

Now plug in your already ready USB drive and restart your computer or, if it is off, turn it on. Just by turning on, even before it displays the brand logo, press the key to go to the boot menu.

As a reminder, here is a small list of the keys to call up the boot menu, according to the brands and models:

HP: Esc or F9. Toshiba: Esc or F12. Lenovo: F12, F8 or F10. Dell: F12. Acer: Esc, F9 or F12. Asus: Esc or F8. Samsung: Esc, F2 or F12. Compaq: Esc or F9. Fujitsu and eMachines: F12.

While turning on your computer, press this key several times in a row (do it quickly) until you have the boot menu:

Boot menu on HP
Boot menu on an HP computer

The image above shows the boot menu on a computer HP, you can see your USB stick in second position (USB Hard Drive).

Boot menu on Lenovo
Boot menu on a LENOVO computer

On this it is the boot menu on a computer LENOVO, you can see your USB stick in second position (USB HDD: USB Disk 2.0).

The position of your USB key is not a problem, since it is indeed recognized by your computer. Select your USB key by scrolling with the keys ↑ ↓ (up and down scroll keys) on your keyboard and enter to install Windows 10.

Starting Windows Setup

If you have this black screen with the Windows icon, you are there. The installation program is starting.

Starting Windows Setup

While loading, wait a few seconds to get this:

System language selection

Select the language your operating system will use and continue:

Selecting the input language (input)

For time format and keyboard (input method), I suggest you leave the default configuration. You can change it later, for now do the following:

Starting the installation of WIndows

You have set the language, click install now:

Starting the installer

Windows starts the installer. This normally requires a few seconds of patience then you can continue:

Selecting the Windows version

The above step, you will not have it for some Windows installation files. Like mine, there are some that offer two versions. And there I chose to install Windows 10 Professional Pre-Activated). Some installation files offer several versions (Starter, Home, Ultimate, Professional, etc.).

In case of several versions, choose according to the use you are going to make of your computer, but I suggest that you always opt for the professional version.

Click on it and do Next:

License terms

Read the terms of the license agreement carefully and, if you agree, accept them by checking the small box "I accept" on the left at the bottom of the window and click Next:

Choice of installation type

Observe in the following image:

Choice of installation type

You notice that the installer offers two types of installation.

The first (Upgrade), can be used when another version of Windows is already installed on the computer. It is simply an update as the files, settings and application will be kept. This option is only available by opening the installer while the computer is in full use.

The second type (custom), is the one we are going to use. This type of installation replaces the existing operating system with a new one. It removes the old system with all its data, settings and issues. Reason why I asked you to start with move your data.

There is still a way to go through this type of (custom) installation without losing data, but that could perhaps be the subject of another article.

Let's continue, click on the second type of installation.

Choice of partition

You cannot pretend to install Windows 10, or other version, without going through partitioning. Observe in the following image:

Selecting the installation disc

You notice that there are three partitions on my disk (Partition 1, 2 and partition 3). These are logical drives belonging to the same physical drive (my hard drive).

Partition 1, as its description indicates, is reserved for the system. Reason why it has such a tiny size (500 Mega). It is a partition that can be extended.

It will contain files like Boot, System Volume Information, $ RECYCLE.BIN etc. When the computer starts up, the files in this partition are the ones that will be read first to load Windows.

The second (score 2 : 99.5 Giga) is then the disk hosting the existing operating system, which is why it is pointed directly by the installation program. It is also the disk in which we will install Windows 10, our new system.

The third partition (132.9 Giga), this is the reserved disk, in which various data are saved and which will not be touched.

Before installing Windows 10, first point the cursor to the first drive (Partition 1 of 500 Mega). Click on it once and go to the bottom of the menu to click on format. A small warning message will be displayed, Accept by clicking OK, it's safe.

Then point the cursor on the second partition (99.5 Giga, in which the new system will be installed), click once on it and go to format it too. By clicking on format, you will get the same attention message:

Formatting the installation disk

Click on OK, and just after click Next (next button on the left at the bottom of the window) and immediately the system will start the installation.

Installation

During the installation, you will have nothing else to do except observe and ensure that the device does not switch off (for example lack of energy). Only, at this level, the computer could restart itself several times. Fortunately, this is part of the process, so don't be worried.

Installation progress

Of these steps, only preparing the files for installation takes time. When completed, the others jump to 100%. In general the installation does not last, it never takes me more than 25 minutes, but the duration depends on the computer concerned (its performance).

Installation progress

Wait, it's almost there.

Preparing to restart

As I told you you don't necessarily need to restart the PC. Windows will do this automatically to continue.

Install Windows 10: Complete the installation

During restart, the program will perform device preparation, wait for the process to reach 100%. It usually doesn't take long.

Preparing peripherals

Finally, after restarting the computer, Windows offers you to perform a configuration or to use a quick configuration:

Quick Windows Setup

Opt to use the quick configuration, you can customize your configurations later.

Wait while Windows completes the operation and prepares your computer for use. Then create your user account by defining the user name (yours) and a password (optional).

Define Username and Password

If you want to set a password, and this is what I recommend you do, use one that you won't be inclined to forget. Enter it twice in a row and put a password hint.

What is a password hint? It is a little word, letter or number that relates to your password and that will help you remember it if you forget it.

For example if you put as a password WINDOWS10, you can put as an indication W10. This is just an example, go for a strong password instead.

Finally, do Next to finish and wait:

Installation of system applications

Windows installs your system applications.

Finalizing the installation

Windows finalizes the installation and prepares your computer for first use.

Computer ready for use

And there you have it, you have just installed Windows 10. Now your computer is ready to use. You can then install your favorite programs there and start using it.

Conclusion

For many people installing Windows is still shrouded in a lot of mysteries. And yet the operation in itself is generally not complicated, although there are still cases where it requires special knowledge. It is necessary to specify it.

Sometimes it seriously complicates. In this kind of case I could be wrong to say that it is always easy and easy to install Windows 10, or any other version for that matter, since it is not always.

Hope this was brief and to the point, and I also hope this article helps you understand the Windows installation process and saves you from always having to hire someone else to do it.
