Want to upgrade to the latest Windows but you internet connection is not strong enough? You can download it elsewhere and have it transferred to a USB flash drive and then install it from there. Having a backup copy of your Windows is also important for all users. But if you’re facing troubles in installing it, here is a step by step guide on how you can install Windows 10 from a USB flash drive.

  1. A USB flash drive containing the Windows 10 ISO file.
  2. A laptop with at least 90% charge and a constant source of charging.
Step 1
Plug In The Flash Drive And Open Bios

Shut down your laptop and then plug in the USB flash drive. Now turn it back on and once the logo of your PC appears press the Bios key. The Bios key is located differently for laptops so check online for it if you don’t know which key acts as your Bios key.

Step 2
Learn How To Operate The Bios Menu

The Bios menu cannot be navigated with the help of the mouse. Rather you have to use the arrow keys to move across options, press enter to select an option, backspace to go back to the previous option, and the escape key to quit the Bios mode. You can also save and quit by using the F10 key.

Step 3
Go To The 'Boot' Menu

The 'Bios' menu will have a number of tabs at the top of the page. Press the 'Direction' keys and go to the tab titled ‘Boot’.

Step 4
Start The Boot Process

Select the first option in the 'Boot' menu by pressing 'Enter', and in the next page choose the ‘USB Storage Device’ option. Once done, press 'F10' and the 'Boot' process should start.

Step 5
Install Windows 10

In the first page that appears choose you language, time zone, and keyboard language by clicking on the drop down menus provided. Click on the ‘Next’ button once done, and in the next page click on the ‘Install Now’ button.

You will now be asked to provide the security key for your Windows 10. Although we support the entering of this key, you can use it later as well by clicking on the ‘Skip’ button. In the following page, agree to the terms and conditions by clicking on the box provided, and then click on ‘Next’.

Now you can create and format partition drives on your PC. You have a list of options to perform these operations and once you are done, once again click on the ‘Next’ button and the Installation process should start.

Step 6
Finish The Installation Process

If you have not yet entered your security key you will once again be asked to enter it, and you may again choose to ‘Skip’ this step. The next page will ask you to enable a particular set of called the ‘Express Settings’. Read through it and choose accordingly, although we suggest the action of enabling the ‘Express Settings’.

Hopefully this tutorial has helped you successfully install Windows 10 from a USB flash drive.
