Вот уж не думал, что возникнет необходимость, но потребовалось записать установочный образ семёрки на DVD
Привод был только на машине с FreeBSD.
Установка необходимого порта:
# cd /usr/ports/sysutils/dvd+rw-tools/ # make -DBATCH install clean # rehash
Переходим в каталог с образом и даём команду
# growisofs -dvd-compat -Z /dev/cd0=win7.iso
Вывод получается примерно следующий
Executing 'builtin_dd if=win7.iso of=/dev/pass0 obs=32k seek=0'
/dev/pass0: "Current Write Speed" is 20.5x1352KBps.
