11. At last, you have to write the bootloader to the USB disk.

If you are using virtual DVD-ROM and its drive letter is G: and your USB stick has the drive letter F:

Then you have to issue the following command :

G:\BOOT\BOOTSECT /NT60 F: /FORCE /MBR

bootloader-writing

In case you have extracted the ISO file of Windows 10 in PC folder then Change the path according to G:\Boot\Bootsect /NT60.

Now you have completed all the process successfully. You can boot from USB drive and install the Windows 10 OS from USB drive. This trick works till Windows 10 RTM version.
