Amiga Forever please help.
 

What am I doing wrong ? I installed Amiga Forever, I select the Amiga 4000 ppc system from the list, it fires up and after a while I get the message "not a DOS disk in device Dh0". I am copying the Amiga 4000 PPC file, edit the 1000 MB disk, install AmigaOS 4.1, everything goes smoothly according to the instructions, after the installation the system starts, I set everything as it should be, reset and again the message that I described above.

Without any more details I would guess that you forgot to install the file system into the partition table (RDB) of the HDF.
