Create Windows 11 Installation USB Flash Drive

1. I follow the instructions from Microsoft site https://www.microsoft.com/en-us/software-download/windows11

 


From the picture above, the way I do is only for x64 processors.

 


From the picture above, I need a blank USB at least 8GB.

 

Download ‘Windows 11 media creation tool’



Open the downloaded file.

 


Click ‘Accept’.

 


Click ‘Next’.

 


Select ‘USB flash drive’. Then Click ‘Next’.

 

 

Attach USB flash drive, and click ‘Refresh drive list’ in the window.

 


Select your target USB flash drive, and click ‘Next’.

 


The app is downloading Windows 11

 


My hard disk has 2 partitions, one Operating System: Windows 11 Home.

 


The app is creating Windows 11 media.

 



When the progress is around 50%, File Explorer will open ‘ESD-USB’ drive.

 


It’s done, click ‘Finish’.

 

2. Change boot priority in the BIOS.

It depends on the brand of your machine. In my case I must press key ‘F2’ without pressing key ‘FN’.

 

Restart Windows, then repeatedly press key ‘F2’

 


There are instructions how to select and move items in the BIOS. I moved ‘USB HDD’ to number one in the list.

 


Save and exit.

 


You will see the ‘Windows 11 Setup’ window.

 


Follow the instructions.
