I found the steps from the below article:


Make sure your USB stick is big enough to accomodate the Windows 7 installation bits. And here below is the summary of steps and output on my own machine:

If "could not be locked" & “Access denied” error happens, try this command: bootsect.exe /NT60 G: /force


Then copy all files from DVD to USB, and there you go!
