ThanX jaclaz, I´ll have a look at these programs! But I´ve never meant to boot the ISOs by itself - normally I´ld burn them with the BURN_FROM_IMAGE_FILE option of NERO - so I want them - lets say - unpacked on my CD but don´t want to unpack them to my HDD first! ..though booting ISOs would be nice - but I doubt this could work - could it ?? btw - GRUB as bootManager of a multi-boot CD - never heard of this before - although I always liked it better than LILO... maybe I´ll have to search the manpage more thorough Bye for now..
