Well, considering I am running it on an Italian release and that I am not including languages, updates & drivers I get missing packages errors when running the packages and cleanup steps.
What kind of errors did you get running removal.bat?
I tried to cleanup a little bit the batch, but if I will get no support into that I am definitely going to give up and use another better explained and better working method.
Judging by your intent and Jeronimo's refusal to help, I recommend Liquid's guide. His is very detailed and even if you make a mistake following his work, you can quickly isolate what and where you went wrong.
If you'd like further help, let me know.
