Create Bootable USB from Windows

I've had amazingly bad luck with different programs and operating systems, just trying to create bootable thumb drives. In Windows, when creating a Windows bootable USB, this seems to work, with the instructions found here:

No promises that this will work everywhere.

C:\> diskpart
Diskpart> list disk
Diskpart> sel disk 1  <-- (the number of your usb)
Diskpart> clean
Diskpart> create part pri
Diskpart> format fs=ntfs quick
Diskpart> Active
Diskpart> Assign

Now copy the install files to the drive, and use it to boot.
