Windows will not boot. Can I install vista on an external hd, copy my old hd to the external hd (minus bad vista), then format the old hd and copy everything back? If that will not work, can I plug in a new internal hd and do the same thing? (I can't see how it would not work on one but not the other, but that's why I'm asking the questions.)
Obviously you have a CD to install, why not just repair-install the current hard drive, unless of course the reason for no boot is a hard drive error to begin with.
