adf's are floppy images, ok for running in winuae, but you have to write them back to floppy disc before use on amiga. I dont think there is any virtual floppy support, although i think somebody was working on a floppy replacement that run from an sd card..
Once you have dumped them back to floppy, you can use a whdload install script to take them from floppy, onto your harddisk.
the whdload installs are over at whdload homepage.
