[12:26] hi, i'm trying to install 10.10 from usb, which fails at the step where the instler wants to mount the (non-existant) cd-rom drive... any help? [12:28] would it be possible to just mount the usb drive to the path the installer wants to mount the cd to? and if yes, what's that path? [12:49] found an empty dvd after all, so i'll just install the traditional way... but somebody should seriously fix that installer or at least include a message where the installation files should be mounted
