Steps to start Windows 10 PC from bootable external USB

In this section We will learn how to start Windows 10 PC from USB. It is divided into a few steps, but first we have to have a pendrive already Booted with Windows 10. If you don’t have a Booted USB, don’t worry because later in this post we will show you how to do it in a few clicks. You can also do it for any other operating system but today we will do it with Windows 10.

Enter BIOS

To be able to make the computer boot from a USB and not from its internal disk we will have to turn off and on the computer to enter the BIOS.

For enter BIOS we must press the key that the system itself teaches us as soon as the computer turns on. For example in the case of us the key to press is F11.


If in your case the computer does not tell you which key to press, since most of the keys that dictate the command to enter the BIOS are the following.

For each time you turn the equipment off and on, you must press a single key of those indicated. If you still cannot enter the BIOS and you do not have a manual for the equipment you are using, you will have the most annoying method; turn the PC off and on as many times as necessary by pressing all the keys in turn (F1; F2; F3…) until it matches the one given by the option.

If you wonder why this is happening, well this is because each manufacturer installs their own commands on their computers, and even computers from the same manufacturer may have different access keys.

Boot from USB

When we get into the “BIOS” for BOOT we can see a list. For some people it may be a little smaller than what we show in the picture. There with the help of the up and down keys We select and press enter on the Booteado device that is going to be used for the installation of the operating system.

If something similar to the list shown in the image does not appear, it is because you could not enter the “BIOS BOOT” Instead, you entered the BIOS menu or another option offered there.


After doing this we will see that all the files on the pendrive begin to be copied to the computer, in turn starting the installer of the operating system which will request that we select, language, time, date until internet connection.

To install Windows 10 you need an internet connectionWell, if the installation can be done without any type of connection, however, if we want a PC with the latest updates and all its features downloaded, it is advisable to do this.

With two steps you can install Windows 10 on your computer. Not only Windows 10 version, you can also do it for 8 or 7, everything according to your taste. As we said there is nothing complicated in this process.

How to create a bootable installer pendrive for Windows 10?

create a bootable installer pendrive for Windows 10

For this we have two methods, one to create an installer pendrive with a CD that has all the Windows 10 files, and the other if you only have the ISO image of the operating system. Both methods are widely used, I hope you are guided by the one that suits you best, and let’s get started.

You cannot start without first knowing that the USB that you are going to use must have a storage capacity greater than or equal to 8GB.

First method

As we already mentioned this method is for copy all the files that are inside the Windows 10 installation CD to a USB turning this into a bootable disk.

Format USB USB that we are going to use, since it should not contain any other foreign file than the one that will be copied from the CD since having it can damage and interfere when installing Windows 10.

First we connect the USB to the computer, we open “Disk manager”, then we click on “Start”, from there we will “Setting” and we select “Create” Y “Format hard disk partitions”.

We format the partition by clicking the second button on the USB drive partition and selecting Format. How is the system necessary FAT32 files to boot the PC based on BIOS or UEFI, is the one we will select. To complete this step we establish the partition as active, clicking on the USB disk partition, pressing the option “Mark Partition“as active.

Extract the installation files. Having already formatted the pendrive that we will use, we insert the installation disc (CD containing Windows 10) into the computer, we wait for the system to read it and open the disc without executing it.

We will see folders and documents that are necessary to install Windows 10, we select everything that is there, copy and paste in the formatted USB. When the whole copy and paste process is complete, remove the CD, the USB. With this simple step we create a bootable USB.

Second method

This is the last method that we are going to show you and the reality is that it is much more sought after than the previous method. With this method we will install Windows 10 on our USB with the help of the Media Creation Tool.

*Note: for this method it is necessary that you have a good internet connection as it will be necessary throughout the process. If you don’t have this tool yet, download it by clicking the following link.

Download Media Creation Tool

This is the official Microsoft page, there we will see an option that says “Download the tool now”, we click on it and we will see how the download begins. This download may take a few minutes, so you must be very patient because this method is easy but requires waiting.

Download Windows 10 on PC

Launch the tool. Once the Windows 10 installation tool has been downloaded, we go to the folder where it was saved and right click on it selecting the option “Execute as an administrator”. The Windows 10 symbol will appear for a few seconds on the screen and the tool will start. This will request that we wait until it is configured correctly.

Boot the pendrive with the tool. Once the installation tool has been correctly configured, it will ask us What do we want to do? From the two options it gives us, we select the second one that says “Create an installation media for another PC”, then we click on “Next” to continue.


Then on the next screen we will see that it asks us to choose the language we want (Spanish), edition (Windows 10 Home) and architecture (64bits). If your situation is different and your PC is 32-bit, just select in architecture the one that appears within the parentheses as x32. To continue we give in “Next” and we wait.

choose the medium

To finish we click on the option that says “USB Flash Drive”, then we select our device and click next. In this way Windows 10 download will begin on the deviceThis process can take minutes and even hours, so we recommend that you make yourself comfortable, if you want to continue using your computer you can do so as long as you do not cancel the installation.
