The image file should contain a disk image, either a floppy disk or hard disk image. The disk image can be compressed with gzip if you have MEMDISK 2.03 or later.
For any other size, the image is assumed to be a hard disk image, and should typically have an MBR and a partition table. It may optionally have a DOSEMU geometry header; in which case the header is used to determine the C/H/S geometry of the disk. Otherwise, the geometry is determined by examining the partition table, so the entire image should be partitioned for proper operation (it may be divided between multiple partitions, however.)

I want to have a business card size CD with which I could boot multiple floppy images (I don't want to carry floppies with me because of their size, fragility, and lack of reliability). I'm posting this because someone might find it useful. Basically I want a CD that has:
NT password reset
Ghost boot disks
Mini (floppy) Linux distribution for recovery and other purposes.
DSL and Puppy floppy images that load DSL or Puppy from USB flash drive (in case the BIOS of the computer does not support USB booting directly).
First, create a folder ~/bootdisk that will hold the images. Download floppy images or rip floppies with
dd if=/dev/fd0 of=~/bootdisk/imagename
(by the way, keep "imagename" under 7 letters because of CD file system limitations).
Install syslinux (use apt-get/Synaptic).
Copy "isolinux.bin" and "memdisk" from /usr/lib/syslinux to the ~/bootdisk folder.
In the ~/bootdisk folder create an "isolinux.cfg" file like this:
default 0 prompt 1 timeout 100 display message.txt label 0 localboot 0x80 label 1 kernel memdisk append initrd=reset label 2 kernel memdisk append initrd=img1 label 3 kernel memdisk append initrd=img2 label 4 kernel memdisk append initrd=puppy label 5 kernel memdisk append initrd=dsl
Explanations:
bypass the CD and boot from localdisk
"reset", "img1", "img2" are the names of floppy images that I put in ~/bootdisk
start the "puppy" and "dsl" floppy images that provide support for USB (in case the computer cannot boot directly from USB)
Again, make sure the image names have less than 7 characters.
Create "message.txt" in ~/bootdisk that contains a menu like this one:
Boot from local disk
Reset NT passwords
Ghost bootdisk Dell GX270
Ghost bootdisk Dell G
Puppy USB support
DSL USB support
Make sure the numbers correspond with the ones in isolinux.cfg (messages.txt is not absolutely necessary, but otherwise you'd need to know the label names when you boot).
Create the iso image, run this command while in ~/bootdisk:
mkisofs -o cdproject.iso -b isolinux.bin -c boot.cat \ -no-emul-boot -boot-load-size 4 \ -boot-info-table ~/bootdisk
Burn cdproject.iso (or test it first in QEMU or VMWare if you don't want to waste a CD)
# apt-get install qemu # qemu -m 256 -cdrom cdproject.iso -boot d
By the way, this is not applicable to boot different ISO files, there are other ways to do that (for example if you want a DVD to contain multiple distros): use this howto
get Puppy Linux, boot from CD, install it to your USB flash drive (use "syslinux" choice).
create and add floppy images in root of USB drive as instructed above.
modify syslinux.cfg in the root of USB drive to point to the floppy images just like in the example above (keep the entry for Puppy) add a messages.txt for the menu.

You can't, sorry.

there is no tool to boot an ISO image.
But you can boot from a CD using isolinux…

I guess it's beyond the scope of the project. The BIOS interface to a CD-ROM is very different than the BIOS interface to a floppy or hard disk. It pretty much would mean writing a different piece of code to emulate a CD-ROM as opposed to emulate a disk.

Write a tool that does it.
Realize that it's probably broken anyway, since most rescue CDs have operating systems that want to talk directly to the hardware…

More than one Linux distro using ISOLINUX is cake.

Typically, ISOLINUX is found in /boot/isolinux. Put the kernel+ramdisk files for each distro in a sub-dir under /boot, as in /boot/mepis for SimplyMEPIS, /boot/slax for Slax KillBill Ed, and /boot/server for Slax Server Ed. The statements shown above work that way.
The files in the root of each distro go into the root of the ISO, exc for Slax Server+KillBill Eds, bec each of those distros have a cmd-line param (from=/) which permit their support files to be placed in their own sub-dirs. Distros based on Knoppix (Knoppix, DSL, et al) are problematic bec they each rely on a /KNOPPIX sub-dir which can't be relocated, otherwise ISOLINUX makes a multi-distro CD/DVD easy. BTW, I would point out that I also integrated BartPE and the CHNTPW P/2K password cracker gizmo into the same ISOLINUX menu with a nice splash screen.

First : For Adding a menu in boot.ini to boot ubuntu/kubuntu linux, here is the steps
Here is the contents of boot.ini
[boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Professional" /noexecute=optin /fastdetect C:\GRLDR="Ubuntu Linux 6.06"
Put the GRLDR from the GRUB in the root
Create a file with the name : menu.lst and fill it with the following contents
color black/cyan yellow/cyan timeout 0 default 0
title Ubuntu 6.06 kernel (hd0,10)/boot/vmlinuz-2.6.15-23-386 root=/dev/sda11 -ro quiet splash initrd (hd0,10)/boot/initrd.img-2.6.15-23-386
Here make the necessary changes for kernel (hd0,10) for the correct partition number and also root=/dev/sda11
Reboot, u will get a menu "Ubuntu Linux 6.06" anext to Windows XP Professional, choose it, then see it will boot into linux
Finished!!

Well, the only solution I could find was to put everything from the CD into the root directory of my AIO DVD. Then I had to use bcdw boot /isolinux/isolinux.bin in order to start Linux. The problem with this, though, is that I can only have one distro on the CD through this method.

Hello all, I plan to make an (emergency) multi OS bootable CD which contain: - Win98 boot floppy (create from Win 98 control panel, add remove program) - WinME boot floppy (create from Win 98 control panel, add remove program) - Linux boot disk - Win NT boot disk - Win 2000 recovery console - Win XP recovery console - Winternal Administrative Pak (ERD Commander etc)
I am new to Linux and feel painful in doing these, someone point me to Bart's web (http://www.nu2.nu/bootcd/) and I guess Multiple boot images (isolinux/memdisk) could solve my problem, I start off with the following
0) Boot from first harddisk (0x80)
1) Boot Dos with CD-Rom support 2) Boot Dos with Network support 3) Boot Linux (tomsrtbt) 4) Boot Windows 98 floppy 5) Boot Windows ME floppy 6) Boot FD Linux 7) Boot Pocket Linux 8) Boot RedHat Linux 8 9) Boot RedHat Linux 8 text e) Boot RedHat Linux 8 expert k) Boot RedHat Linux 8 ks n) Boot RedHat Linux 8 nofb l) Boot RedHat Linux 8 lowres c) Boot RedHat Linux 8 CrashRecovery
a) Boot from first floppy drive (0x00) q) Skip CD-Rom boot (try next boot device)
1,2,3 are from Bart's web, I create the img file (win98.img and winme.img) with dd.exe I got FD Linux at http://www.fdlinux.com/download.html and Pocket Linux at http://www.pocket-lnx.org/download.html option 8,9,e,k,n,l are from http://redhat.pacific.net.au/redhat/linux/8.0/en/os/i386/isolinux/ and c) is from http://crashrecovery.org/ (ftp://ftp.crashrecovery.org/pub/linux/CrashRecoveryKit/iso/2.4.19/) my isolinux.cfg look like this

label c

timeout 200
I have no problem from Option 0 - 4, but can't load the remain, 5) hang up after winme.img load, 6) and 7) ask for floppy, 8 - l report vmlinuz corrupt, c) hang after image load.
