Bootable CD?

rasat · 2003-05-31 04:49:43

I don't have much experience burning CDs but I found K3B a good software.

How to make a bootable CD. Can it be done with K3B?
On internet there are websites describing the process, but I am looking for a simple step-by-step instruction (if possible).

i would assume that k3b can do it. look for and option to burn bootable cd image.

however if this disc you wsh to burn is a bootable disc already in iso format all you would have to do is burn it. if it is not i believe there is an option in mkisofs (which k3b uses) that allows the image to be made bootable.

I installed gcombust and it looks fine for my purpose. Any idea where I can get the required boot.img and boot.catalog? Is there anywhere to download or do I have to copy from a bootable floppy disk?

those are files you create.

I found some useful instructions:
http://nic.phys.ethz.ch/readme/41

The key in this process is the pre-made image file iso is created. The website used "partimage-x.y.z-bootcd-w.img" from: http://prdownloads.sourceforge.net/sour … partimage/ .
To create pre-made image from a bootable floppy disk....
1. Insert a bootable floppy disk.
2. Create boot.img in /test folder.
# cd /test
# dd if=/dev/fd0 of=boot.img bs=10k count=144
Question: how do you make your own pre-made image if you don't want to be depended on Red Hat's, SuSE, or whatever distro's bootable floppy? An image where you have your own selected files and folders at boot (ramdisk).

Note:
I am planning to make an Arch Linux live CD. (with hd-install script).

You can always rip the one out of the current Arch cd... or grab the boot and root disk images (probably better off the cd).

There are programs to do just that. Bootable cds are sometimes called el torito (toritto? something like that), search on that phrase and you'll find programs to get the boot image out of an iso. From there it's really easy to modify it (mount it through the loopback) and put it into another cd.

Tada.

Thanks Xentac for the hints.

Could not find for Linux. Most programs are Windows based. I tried Magic ISO Maker (with Win4Lin). Works well to open and edit iso files.

Mount an image file (sampleBoot.img):
# mount -t auto -o loop sampleBoot.img /mnt/image
# cd /mnt/image
(add or edit files to /mnt/image)

Create an image file (MyBoot.img):
# mkfs.msdos -C MyBoot.img 2880 (creates an empty 2.88Mb MyBoot.img)
(mount and add boot files)

just so i'm on the same page as everyone... these bootable cd's you're talking about making are like knoppix where you don't have to install it on the hard drive, right? not that they are just bootable to install? am i making any sense?

Yes, you are right.... its a Live CD where everything runs from CD. The Live CD is ready if you are interested:
