turn mint12 iso into a hybrid image

Fri Feb 03, 2012 1:36 am

The following is how I turn a mint12 iso into a hybrid image.

First, you need to be using a distro that does support hybrid images.

I downloaded linuxmint-12-gnome-cd-nocodecs-32bit.iso and that is what I will use as an example. It was downloaded to my home folder which is also where I will be working at in the terminal.

Install syslinux, genisoimage, and rsync.

Then open a terminal and su to root (or use sudo)

make a folder for the extracted iso
mkdir iso

make a folder to mount the iso so we can copy the contents
mkdir mntiso

mount the iso
mount -o loop linuxmint-12-gnome-cd-nocodecs-32bit.iso mntiso/

copy the contents of the iso to the iso folder
rsync -a mntiso/ iso/

unmount the iso
umount mntiso/

remove the folder
rm -rf mntiso/

remove the incompatible isolinux.bin file
rm iso/isolinux/isolinux.bin

remove the incompatible vesamenu file
rm iso/isolinux/vesamenu.c32

copy a compatible isolinux.bin file from the system
cp /usr/lib/syslinux/isolinux.bin iso/isolinux/

copy a compatible vesamenu.c32 file from the system
cp /usr/lib/syslinux/vesamenu.c32 iso/isolinux/

create the iso image *
genisoimage -r -J -l -D -o ./mint12hybrid.iso -cache-inodes \
-b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 \
-boot-info-table -input-charset UTF8 iso/


make the image a hybrid image
isohybrid mint12hybrid.iso

remove the iso folder
rm -rf iso/

You should see the mint12hybrid.iso in whatever folder you did this in.

Done.

Then you can dd the image to a usb stick to boot from. THIS WILL ERASE EVERYTHING ON THE USB DEVICE! Change /dev/sdb to whatever device your usb stick is.
dd if=mint12hybrid.iso of=/dev/sdb





* The genisoimage command is one long command. The \ at the end of each line allows it to be split up.
So you enter the first line
genisoimage -r -J -l -D -o ./mint12hybrid.iso -cache-inodes \
and press enter
then enter the next line
-b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 \
and press enter
then enter the next line
-boot-info-table -input-charset UTF8 iso/
and press enter


You can type the whole thing in at once if you prefer. Type in the whole command and then press enter.
Code:
genisoimage -r -J -l -D -o ./mint12hybrid.iso -cache-inodes -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table -input-charset UTF8 iso/
