Issue: Upon install, the process hangs in an infinite (?) loop circling between chosing language and creating / transferring an user acount ("Do you already own a mac?").
According to the forum, the problem seems to be connected to problems concerning the network card.

Solution 1: Importing an account from an existing (Tiger) installation.

Solution 2: Booting with the flag "Graphics Mode"="640x480x32". The resulting low screen-resolution prevents the setup screen, thus skipping the "loop". As one is not able to create a new username, only the default "admin" is created. This can be changed later on.

Solution 3: Some people reported success with disabling the network card in the bios or disconnecting the cable.

Solution 4: Boot using "-s" flag then type ->

/sbin/mount -uw /

passwd root <- Type any password you want

touch /var/db/.AppleSetupDone

reboot
