Sorry, I didn't have that problem when I used it myself and I've used it on
a few occasions so in answer to your question, "Yes, indeed I not only
checked what I recommended but have in fact used it on my setup." Kelly
Theriot who created the site and is a fellow MVP well be interested in
knowing the problem you had and may have some questions in that regard
though it may not be immediately as she is currently offline and expect her
to be so for a few weeks.
I do sincerely apologize for any trouble this may have caused you, I'd also
point out the third line in my signature, something I post with ever
response.
My point is, there is always a chance, with anything you might do to resolve
an issue that you have, the system may become unbootable or files you don't
wish to be deleted are deleted or the USER might actually make an error in
following the instructions and cause a problem. I often offer the advice
and step by step instructions for performing a repair install. While this
is supposed to be non-destructive, it will on occasion render a system
unbootable, even when the USER has followed instructions exactly as posted
as things can and do go wrong and I do strongly emphasize in my instructions
that they should be well backed up even though I consider that a give for
everyone. Perhaps I should have offered that in my recommendations to you
as well though I've never seen this issue with this particular
recommendation and had no reason beyond the fact it's a computer and as
stated above, anything can go wrong, to assume this danger existed.
First rule of good computing, "Make good backup."
Again, I'm sorry for the problem but I've used it and I've posted it for
others and while there have been times when it didn't resolve the issue,
this is the first I've heard from anyone that it caused the problem you
specify.
I understand your being annoyed and even the need to lash out and cast blame
but the implications of your post are flat out wrong. I have used the
advice and I've posted it for others. I haven't tested it on every single
user setup imaginable but the experience I have had up to this point has
been non-destructive.
