I'd be inclined to try rufus (search Google for that) to create the bootable USB stick. Are you using Windows to create the bootable USB?
You can tell rufus to create the image from an iso file and it will do the whole thing for you. I find this easier than other utilities for creating bootable USB's.
Give that a go and post back your progress, or lack of.
I have a .dmg file which was created from a disk consisting of two partitions. When I mount the dmg both partitions pop up, so I know the imaging worked properly. One partition is HFS+ and the other is FAT32.
So far, I've been unable to find a way to restore the dmg to a flash drive where both... (17 Replies)

Makebootfat Bootable FAT Disk Creation(1) General Commands Manual Makebootfat Bootable FAT Disk Creation(1)NAME
makebootfat - Makebootfat Bootable FAT Disk Creation
SYNOPSIS
makebootfat [options] IMAGE
DESCRIPTION
This utility creates a bootable FAT filesystem and populates it with files and boot tools.
It is mainly designed to create bootable USB and Fixed disk for the AdvanceCD project.
The official site of AdvanceCD and makebootfat is:
http://advancemame.sourceforge.net/
OPTIONS -o, --output DEVICE
Specify the output device. It must be the device where you want to setup the filesystem. You can use the special "usb" value to
automatically select the USB Mass Storage device connected at the system. This option is always required.
-b, --boot FILE
-1, --boot-fat12 FILE
-2, --boot-fat16 FILE
-3, --boot-fat32 FILE
Specify the FAT boot sector images to use. The -b option uses the same sector for all the FAT types. The other options can be used
to specify a different sector for different FAT types. The FAT types for which a boot sector is not specified are not used. This
option is always required.
-m, --mbr FILE
Specify the MBR sector image to use. If this option is specified a partition table is created on the disk. Otherwise the disk is
filled without a partition table like a floppy disk.
-F, --mbrfat
Change the MBR image specified with the -m option to pretend to be a FAT filesystem starting from the first sector of the disk. This
allows booting from USB-FDD (Floppy Disk Drive) also using a partition table generally required by USB-HDD (Hard Disk Drive). The
MBR image specified with the -m option must have executable code positioned like a FAT boot sector. You can use the included 'mbr-
fat.bin' file.
-c, --copy FILE
Copy the specified file in the root directory of the disk. The file is copied using the readonly attribute.
-x, --exclude FILE
Exclude the specified files and subdirectories in the IMAGE directory to copy. The path must be specified using the same format used
in the IMAGE directory specification.
-X, --syslinux2
Enforce the syslinux 2.xx FAT limitations. Syslinux 2.xx doesn't support FAT32 at all, and FAT16 with 64 and 128 sectors per cluster
formats. This option excludes all the FAT formats not supported by syslinux. Please note that it limits the maximum size of
filesystem to 1 GB.
-Y, --syslinux3
Enforce the syslinux 3.xx FAT support. Syslinux 3.00 supports all the FAT types and sizes but it requires a special customisation of
the boot sector and of the file 'ldlinux.sys'. This option does this customisation without the need to use the syslinux installer
if the 'ldlinux.sys' file is copied on disk with the -c option.
-Z, --zip
If possible force the ZIP-Disk compatibility. It sets a geometry of 32 sectors and 64 heads. It also uses the 4'th partition entry
in the partition table. It's required to boot also in USB-ZIP mode.
-P, --partition
Ensure to operate on a partition and not on a disk.
-D, --disk
Ensure to operate on a disk and not on a partition.
-L, --label LABEL
Set the FAT label. The label is a string of 11 chars.
-O, --oem OEM
Set the FAT OEM name. The OEM name is a string of 11 chars.
-S, --serial SERIAL
Set the FAT serial number. The serial number is a 32 bit unsigned integer.
-E, --drive DRIVE
Set the BIOS drive to setup in the FAT boot sector. Generally this value is ignored by boot sectors, with the exception of the
FAT12 and FAT16 FreeDOS boot sectors that require the correct value or the value 255 to force auto detection.
-v, --verbose
Print some information on the device and on the filesystem created.
-i, --interactive
Show the errors in a message box. Only for Windows.
-h, --help
Print a short help.
-V, --version
Print the version number.
IMAGE Directory image to copy on the disk. All the files and subdirectories present in this directory are copied on the disk.
DISKS AND PARTITIONS NAMES
In Linux disk devices are named /dev/hdX or /dev/sdX where X is a letter. Partition devices are named /dev/hdXN or /dev/sdXN where X is a
letter and N a digit.
In Windows disk devices are named \.PhysicalDriveN where N is a digit. Partition devices are named \.X: where X is a letter, but some-
times \.X: is a disk and not a partition, for example on floppies and on all the USB Mass Storage devices without a partition table.
SYSLINUX
To make a bootable FAT using syslinux you must use the -X option for syslinux version 2.xx or the -Y option for syslinux version 3.xx. You
must also copy in the root directory of the disk the files:
ldlinux.sys The syslinux loader.
syslinux.cfg The syslinux configuration file.
linux The Linux kernel image (the file name may be different).
initrd.img The initrd filesystem (the file name may be different or missing).
You must also specify the 'ldlinux.bss' boot sector with the -b option and possibily the 'mbr.bin' MBR sector with the -m option. Both the
sector images are present in the syslinux package.
For example:
makebootfat -o usb
-Y-b ldlinux.bss -m mbr.bin
-c ldlinux.sys -c syslinux.cfg
-c linux -c initrd.img
image
LOADLIN AND FREEDOS
To make a bootable FAT using loadlin and FreeDOS you must copy in the root directory of the disk the files:
kernel.sys The FreeDOS kernel. Remember to use the "32" kernel version to support FAT32.
command.com The FreeDOS shell.
autoexec.bat Used to start loadlin.
loadlin.exe The loadlin executable.
linux The Linux kernel image (the file name may be different).
initrd.img The initrd filesystem (the file name may be different or missing).
You must also specify the FreeDOS boot sectors available on the FreeDOS 'sys' source package with the -1, -2, -3 option. For the MBR you
can use the sectors image available on the FreeDOS 'fdisk' source package.
For example:
makebootfat -o /dev/hda1
-E 255
-1 fat12com.bin -2 fat16com.bin -3 fat32lba.bin
-c kernel.sys -c command.com
-c autoexec.bat -c loadlin.exe
-c linux -c initrd.img
image
MULTI STANDARD USB BOOTING
The BIOS USB boot support is generally differentiated in three categories: USB-HDD, USB-FDD and USB-ZIP.
The USB-HDD (Hard Disk Drive) standard is the preferred choice and it requires the presence of a partition table in the first sector of the
disk. You can create this type of disk using the -m option.
The USB-FDD (Floppy Disk Drive) standard requires the presence of a filesystem starting from the first sector of the disk without a parti-
tion table. You can create this type of disk without using the -m option.
The USB-ZIP (ZIP Drive) standard requires the presence of a device with a very specific geometry. Specifically, it requires a geometry with
32 sectors and 64 heads. It also requires the presence of a partition table with only a bootable partition in the fourth entry. You can
create this type of disk using the -m and -Z option.
Generally these standards are incompatible, but using the -m, -F and -Z options you can create a disk compatible with all of them.
To use the -F option, the MBR image specified must follow the constrains:
o It must start with a standard FAT 3 bytes jump instruction.
o It must have the bytes from address 3 to 89 (included) unused.
And example of such image is in the 'mbrfat.bin' file.
For example to create a syslinux image:
makebootfat -o usb
-Y-Z-b ldlinux.bss -m mbrfat.bin -F-c ldlinux.sys -c syslinux.cfg
-c linux -c initrd.img
image
and for a FreeDOS and loadlin image:
makebootfat -o usb
-E 255
-Z-1 fat12com.bin -2 fat16com.bin -3 fat32chs.bin
-m mbrfat.bin -F-c kernel.sys -c command.com
-c autoexec.bat -c loadlin.exe
-c linux -c initrd.img
image
Please note that FreeDos has some problems booting from USB. It works only on very few conditions.
EXCLUSION
To exclude some files or directories in the image copy, you can use the -x option using the same path specification which are you using for
the image directory.
For example, if you need to exclude the 'isolinux' and 'syslinux' subdirectories from the 'image' directory you can use the command:
makebootfat ...
-x image/isolinux
-x image/syslinux
image
