https://askubuntu.com/a/122506/209043 wget http://www.instalinux.com/download/iso1132.iso -O /root/iso1132.iso wget http://www.instalinux.com/download/preseed1132.txt -O preseed.cfg --- The complete solution is: Remaster a CD, ie, download a non graphical ubuntu installation ISO (server or alternate installation CD), mount it $ sudo su - # mkdir -p /mnt/iso # mount -o loop ubuntu.iso /mnt/iso Copy the relevant files to a different directory # mkdir -p /opt/ubuntuiso # cp -rT /mnt/iso /opt/ubuntuiso Prevent the language selection menu from appearing # cd /opt/ubuntuiso # echo en >isolinux/lang Use GUI program to add a kickstart file named `ks.cfg` # apt-get install system-config-kickstart # system-config-kickstart # save file to ks.cfg To add packages for the installation, add a `%package` section to the `ks.cfg` kickstart file, append to the end of `ks.cfg` file something like this. %packages @ ubuntu-server openssh-server ftp build-essential This will install the ubuntu-server "bundle", and will add the `openssh-server`, `ftp` and `build-essential` packages. Add a preseed file, to suppress other questions # echo 'd-i partman/confirm_write_new_label boolean true d-i partman/choose_partition \ select Finish partitioning and write changes to disk d-i partman/confirm boolean true' > ks.preseed Set the boot command line to use the kickstart and preseed files # vi isolinux/txt.cfg Search for label install menu label ^Install Ubuntu Server kernel /install/vmlinuz append file=/cdrom/preseed/ubuntu-server.seed vga=788 initrd=/install/initrd.gz quiet -- add `ks=cdrom:/ks.cfg` and `preseed/file=/cdrom/ks.preseed` to the append line. You can remove the `quiet` and `vga=788` words. It should look like append file=/cdrom/preseed/ubuntu-server.seed \ initrd=/install/initrd.gz \ ks=cdrom:/ks.cfg preseed/file=/cdrom/ks.preseed -- Now create a new iso # mkisofs -D -r -V "ATTENDLESS_UBUNTU" \ -cache-inodes -J -l -b isolinux/isolinux.bin \ -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 \ -boot-info-table -o /opt/autoinstall.iso /opt/ubuntuiso That's it. You'll have a CD that would install an Ubuntu system once you boot from it, without requiring a single keystroke. --- To bypass the need to press enter on boot change the timeout value from `0` to `10` in `/isolinux/isolinux.cfg`: timeout `10` Note that a value of `10` represents `1` second --- # Last mkisofs -D -r -V "ATTENDLESS_UBUNTU" -cache-inodes -J -l -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /root/autoinstall.iso /opt/ubuntuiso
