the girl explains that well but It went a step ahead as she has already some files installed on winuae and she starts from those ones above all when it says about the file system for large partitions and what I actually would need is to install the 0.39 on my 16gb through winuae from zero with all the steps giving 2 gb for the os boot partition so to install akreal later on and leaving the rest for the games though ......so if you could give me a tip, I'd thank you a lot....I think that now I have messed up everything..
update: also found this one similar but exhaustive with all steps to be done...quite cool for noobs!
