I am not a computer scientist either, but I am somehow familiar with computers in labs.
Given the situation, to simplify your life:
1] make a backup of your /home on an external haddrive (an effective external hard drive, on an other computer, ...);
2] forget the Fedora stuff and install Debian from _scratch_ ;
3] after installation, backup back you /home folder (and check that the former privilege policy of your /home is
compatible with the Debian policy).
I can not help on what is really going on, but by experience, to put it simply, I know that Fedora is ``messy'' (compare to Debian):
if you keep your Fedora material, you may encounter minor but annoying difference (as different version, different default options, ...)
that may pollute you life not only during the installation but also afterwards.
Installing from scratch may seem a waste of time, but it is not in fact because you de facto discard a long list
of potential highly annoying and subtil issues. On the list, you will even find some people that encourage
installation from scratch for Debian release upgrading. Anyway, the waste of time will be due mainly to backups:
during backups, take a break, drink cups of tea, or read Debian manuals.
Bon courage,
