How to make a Windows 10 Bootable USB stick that support UEFI boot.

Requirements:

4 Gb USB stick/flash drive
Windows 10 Pro/Enterprise/Education Installation files (either their own image, MSDN or from the Volume Licensing website)
A PC or tablet!

Make a bootable USB flash drive using DISKPARTRun CMD.EXE as an administrator (Win-X then A), then run DISKPART with the following commands (not case-sensitive):

Command	What it does
LIST DISK	Shows all mounted disks. Find your USB flash
SELECT DISK n	Selects the disk that future commands will use. Replace ‘n’ with the disk # for your USB flash drive.NOTE: Be careful that you don’t select your hard disk! The next command will wipe the selected drive clean.
CLEAN	Erases all previous partition & volume information on the flash drive.
CREATE PARTITION PRIMARY	Partitions the flash drive as one partition for the whole drive.
SELECT PARTITION 1	Selects the new partition so future commands will operate on it.
ACTIVE	Marks the new partition as active so the BIOS/UEFI can boot to it.
FORMAT FS=FAT32 QUICK	Formats the partition as FAT32.(NOT NTFS!) EXTREMELY IMPORTANT!
ASSIGN	Assigns a drive letter to the flash drive.
EXIT	Exits DISKPART

At this point your USB drive is formatted. DO NOT format the drive with Windows Explorer or format.com; you will not be able to boot from it.

Simply Copy files to the USB Drive and Prep the Windows 10 Image on the USB drive.

1. Copy Files

Use File Explorer

Copy files using (use XCOPY or ROBOCOPY) both of which are available in Windows 7/8/10.robocopy <source directory> <usb flash drive root directory> /mir
Example: robocopy d:\Win10Files e:\ /mir
(Change the destination to the folder that you have extracted Windows image on disk)

2. Prep the USB using CMD

Run CMD
Go to the directory where your winfiles are
cd boot (e.g. c:\win10pro\boot\)
bootsect /nt60 X: (X is the drive latter of your USB drive )

Booting from the USB drive:Method 1:

Enter UEFI/BIOS Screen
Set to boot from USB
Disable Secure Boot

Method 2

Press Windows Key + R
Enter : shutdown.exe /r /o /f /t 00
After the system restarts – Click boot from another device

Why do I need to do all this fuss? -Most new devices are delivered with UEFI instead of BIOS. Alot of security benefits here. Some of you might experience that these devices do not automatically boot from a bootable key that you plug in. Please follow my instructions above.

When you are ready.

1. Do not insert the USB key yet, boot your device first.

2. Once your device is in Windows insert your USB Key, swipe on the right side to bring out the charms. Select Settings
