2 ISO Ubuntu i386 i AMD 64 na 1 DVD

Znači imate 2 ISO datoteke, i386 i AMD 64 i želite to na 1 DVD, da bi uštedjeli 1 DVD. :-)

Postupak je sljedeći (npr. za Ubuntu 12.04):

1. ubuntu-12.04-desktop-i386.iso i ubuntu-12.04-desktop-amd64.iso ubacite u $HOME folder.

2. Kreirajte folder za DVD:
mkdir -p ubuntu-12.04-desktop-i386-amd64/boot/{grub,iso}

3. mv ubuntu-12.04-desktop-{i386,amd64}.iso ubuntu-12.04-desktop-i386-amd64/boot/iso/

4. Kreirajte datoteku (pratite lokaciju!) ubuntu-12.04-desktop-i386-amd64/boot/grub/grub.cfg i dodajte sljedeće:
# Derived from /boot/grub/loopback.cfg from ubuntu-12.04-desktop-i386.iso and ubuntu-12.04-desktop-amd64.iso.

menuentry "Try Ubuntu without installing (32-bit)" {
loopback iso /boot/iso/ubuntu-12.04-desktop-i386.iso
linux (iso)/casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=/boot/iso/ubuntu-12.04-desktop-i386.iso quiet splash --

}
menuentry "Try Ubuntu without installing (64-bit)" {
set gfxpayload=keep
loopback iso /boot/iso/ubuntu-12.04-desktop-amd64.iso
linux (iso)/casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=/boot/iso/ubuntu-12.04-desktop-amd64.iso quiet splash --

}
menuentry "Install Ubuntu (32-bit)" {

}
menuentry "Install Ubuntu (64-bit)" {
loopback iso /boot/iso/ubuntu-12.04-desktop-amd64.iso
linux (iso)/casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity iso-scan/filename=/boot/iso/ubuntu-12.04-desktop-amd64.iso quiet splash --

}
menuentry "Check disc for defects (32-bit)" {
loopback iso /boot/iso/ubuntu-12.04-desktop-i386.iso
linux (iso)/casper/vmlinuz boot=casper integrity-check iso-scan/filename=/boot/iso/ubuntu-12.04-desktop-i386.iso quiet splash --
initrd (iso)/casper/initrd.lz
}
menuentry "Check disc for defects (64-bit)" {
loopback iso /boot/iso/ubuntu-12.04-desktop-amd64.iso
linux (iso)/casper/vmlinuz.efi boot=casper integrity-check iso-scan/filename=/boot/iso/ubuntu-12.04-desktop-amd64.iso quiet splash --
initrd (iso)/casper/initrd.lz
}
menuentry "Test memory" {
loopback iso /boot/iso/ubuntu-12.04-desktop-i386.iso
linux16 (iso)/install/mt86plus
}

5. Kreirajte ISO datoteku (morate imati instaliran xorriso):
grub-mkrescue --output ubuntu-12.04-desktop-i386-amd64.iso ubuntu-12.04-desktop-i386-amd64

6. Sada možete spržiti ubuntu-12.04-desktop-i386-amd64.iso u DVD i pri bootanju birati 32-bit ili 64-bit.
