hi,
i faced exactly the same problem you discussed in this topic.
was almost able to solve it but once i got into this recovery console
i had type in a password of the administrator which i dont know.
i tried several keywords that i guessed (also tried to just enter without a word) but couldnt succeed.
but notice that i inserted a win xp pro cd even though win xp home version is installed. i had borrowed the home cd to somebody else.
and i am afraid that i cannot recover my data.
do you think with the home version cd there wont be this question?
