Dual Boot Puppy Linux With Ubuntu

Puppy Linux is so nice that I always keep it around even if I don't need it. I have a small partition on my laptop where I install different versions of Puppy, and they co-exist with my main Ubuntu (actually Xubuntu) system. The installation is very easy.

Lately I have installed Precise Puppy 5.6.1 and Slacko Puppy 5.5 . After downloading the .iso files, I extracted them and copied their content on /dev/sda9 like this:

sudo su

mkdir sda9
mount /dev/sda9 sda9/

mkdir iso
mount -o loop precise-5.6.1.iso iso/
mkdir -p sda9/puppy/precise5.6.1
cp -a iso/* sda9/puppy/precise5.6.1/

umount iso/
mount -o loop slacko-5.5-PAE.iso iso/
mkdir -p sda9/puppy/slacko5.5
cp -a iso/* sda9/puppy/slacko5.5/

umount iso/
rmdir iso/
umount sda9/
rmdir sda9

The installation is already finished! But we need a way to boot the puppies. We can do this by modifying the grub menu. First add these lines on the config file  /etc/grub.d/40_custom:

menuentry "Puppy Linux Slacko 5.5 frugal (sda9/puppy/slacko5.5)" --class gnu-linux --class gnu --class os {
    set root='(hd0,msdos9)'
    #find --set-root --ignore-floppies /puppy/slacko5.5/initrd.gz
    linux /puppy/slacko5.5/vmlinuz pmedia=atahd psubdir=puppy/slacko5.5
    initrd /puppy/slacko5.5/initrd.gz
}

menuentry "Puppy Linux Precise 5.6.1 frugal (sda9/puppy/precise5.6.1)" --class gnu-linux --class gnu --class os {
    set root='(hd0,msdos9)'
    #find --set-root --ignore-floppies /puppy/precise5.6.1/initrd.gz
    linux /puppy/precise5.6.1/vmlinuz pmedia=atahd psubdir=puppy/precise5.6.1
    initrd /puppy/precise5.6.1/initrd.gz
}

Then run the command sudo update-grub.

Now reboot the PC and have fun with Puppy.
