Before creating the disk image you must copy your roms and other
files under the image/arcade/ directory.

Generally you need only to add roms in the image/arcade/rom directory
and snapshots in the image/arcade/snap directory.

Eventually you can also add other files in the following
directories:

For AdvanceMAME:
image/arcade/rom - The .zip roms.
image/arcade/image - The .chd harddisk images.
image/arcade/diff - The .dif harddisk differential images.
image/arcade/sample - The .zip samples.
image/arcade/artwork - The .zip artworks.
image/arcade/bezel - The .zip bezels.

For AdvanceMESS:
image/arcade/bios - The .zip bios.
image/arcade/software - The .zip software.

For AdvanceMENU:
image/arcade/snap - The .png, .mp3, .mng snaps.
image/arcade/flyer - The .png flyers.
image/arcade/marquee - The .png marquees.
image/arcade/cabinet - The .png cabinets.
image/arcade/icon - The .ico icons.
image/arcade/music - The background .mp3 music.

Anyway check that you can boot from a bootable cd on your machine.
