This morning I re-try complete manual installation , this time using your guide sir Gringo Vermelho and I solve all.
Point of my disaster is fseventsd. In fact many times I dont understand strange disappearances of files, or view another files.
And many times i dont umount EFI.
touch /Volumes/EFI/.fseventsd/no_log
So, many thanks to you and to moderator mr Blackosx for his support.
After firsts failed manual installations i've try to use champlist, but always fails. Now with your guide bootloader is in graphic mode with branch 2.1.
PS Probably many people dont know this little problem and many manuals or maybe automatic script like champlist dont (this is only my assumption, i dont know champlist code source) include fseventsd trick.
Best regards, mrhevor.
