Have a new Win 8 laptop and would like to dual boot Win 7 as well. No optical drive and only a recovery partition. Google only turned up one post saying the file system is incompatible so it's necessary to install Win 7 and then Win 8. But I don't have any media to reinstall Win 8 with unless the recovery partition can be used (never had to use a recovery partition so don't know what's possible). Anyone have any insights?
