Hey! After having some problems with Parallels 3 and Windows Service Pack 3 (It wasn't possible to launch WinXP Bootcamp via Paralles after updating to service pack 3), I upgrated to Paralles 4. It seemed, everything went fine, but while upgrading, I got some small errors. But anyway, I could update Parallels and launch my system. Quite happy of that, because ist was possible to boot the system, which wasn't possible before, I realized, that Parralles wasn't able to boot my DVD Drive of my iMac. The error said, that a driver / file / another hardware is missing, or the drive is in use, or I doesn't have the rights to use my DVD drive. Now, I searched the web, but didn't find an answer. So, it would be quite cool, if you have an idea.... I doesn't have uninstalled the VM so far, maybe there is a hint to solve my problem. If not, first I would uninstall the VM an give a new one a chance, because I didn't register Win so far. Thanks for your help! Regards! blub
