In late 2019 I successfully ship multiboot drives with Zorin OS as one among many operating systems within them. I have made the articles in making them multibootable most notably openSUSE, Deepin, and Slackware, as they were actually not supported by GLIM multiboot maker. However, I forgot that I have not made such article about Zorin as I thought I have. Now I remembered it in 2020 and this is the article you can learn once again to make it bootable like what I am currently doing with my latest Zorin articles. Enjoy!
Get Zorin OS
Download it at zorinos.com.
Change inc-zorin.cfg
Create a new file named inc-zorin.cfg in your flash drive's boot/grub/ directory and save code text below.
# Zorin
for isofile in $isopath/zorin/Zorin-*.iso; do
if [ ! -e "$isofile" ]; then break; fi
regexp \
--set 1:isoname \
--set 2:version \
--set 3:variant \
--set 4:arch \
"^${isopath}/zorin/(Zorin-([^-]+)-([^-]+)-([^-]+)\.iso)\$" "${isofile}"
menuentry "Zorin OS ${version} ${arch} ${variant}" "${isofile}" "${isoname}" --class zorin {
set isofile=$2
set isoname=$3
echo "Using ${isoname}..."
loopback loop $isofile
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=${isofile} quiet splash
initrd (loop)/casper/initrd.lz4*
}
done
Change grub.cfg
Add code lines below into your flash drive's grub.cfg where the image file is located under boot/iso/zorin/ directory and the file name is in Zorin-*.iso format. Remember that it is case sensitive.
for isofile in ${isopath}/zorin/Zorin-*.iso; do
if [ -e "$isofile" ]; then
menuentry "Zorin >" --class zorin {
configfile "${prefix}/inc-zorin.cfg"
}
break
fi
done
Add Zorin icon
Download this small zorin.png and save it into your flash drive's boot/grub/themes/invader/icons/ directory.
Boot
Now boot your flash drive and you should see Zorin OS presented to choose along with other operating systems you have in that drive.
