this is an option, that is slightly different, but it is not guarenteed that the boot disk will be recognized as a bootable device with every motherboard.
Removing the extra boot drive is not that big of a deal, but it can be annoying i suppose, i find it to be more useful if a re-install is needed, as it can be completed without anything, but restarting in dos.
*always good to have other options, good post
