Tazusb is a tool that can create bootable usb media with a few simple commands. It can also compress and backup the entire current filesystem to the media, thus preserving all modifications for future use. Type tazusb usage for a full list of commands or read the TazUSB manual.

To generate your own LiveUSB media, first you need to login as root with su and locate your usb storage device using the command:

# fdisk -l /dev/sdxx 

Then format and label your device (Warning: this will erase all data, make sure you specify the right device):

 # tazusb format /dev/sdxx 

And finally generate your LiveUSB media device with either:

 # tazusb gen-liveusb /dev/sdxx 

(if you're working with a LiveCD as the install source)

OR

 # tazusb gen-iso2usb slitaz.iso /dev/sdxx 

(if you're working with an iso file as the install source)

Note that the /dev/sdxx part of the command above specifies the location to where you need to write the iso's files to; it is not the source media where the iso is on ! With the iso file as install source option, you should hence specify the exact location where the slitaz iso source file is located. If it is located at /home/tux (while running slitaz from a non-live version), write “tazusb gen-iso2usb /home/tux/slitaz.iso /dev/sdxx”. If the source file is found on an external hard disk, mention the folder in which the media's files are outputted to - check this with PCManFM (in practice the folder can be something like /media/disk). So, the command you'd need to write with the latter would be something like “tazusb gen-iso2usb /media/disk/slitaz.iso /dev/sdxx”

And that's all you need to do, you can now boot SliTaz from usb media (providing your computer bios supports this method).

The official Tazusb manual can be found in the SliTaz Web site documentation; this contains a lot more useful information. The manual is also available through the documentation menu on the LiveCD.

Slitaz can be installed on USB media from windows. The following description has been tested on Windows XP and Vista. Before starting you need to download:

1. the latest SliTaz iso from Get SliTaz.
2. the syslinux tool for the SliTaz version you install:

• syslinux-4.05.zip for SliTaz 4.0
• syslinux-3.82.zip for SliTaz 3.0
• syslinux-3.73.zip for SliTaz 2.0
• syslinux-3.61.zip for SliTaz 1.0

1. Extract the SliTaz ISO file to the USB stick. For this, use a tool like 7-Zip or Winimage (shareware). Once extracted, you should get the following:

\boot
\boot\isolinux
\boot\grub

2. On your USB stick, rename the \boot\isolinux directory to \boot\syslinux.

3. In the new directory \boot\syslinux, rename isolinux.cfg file to syslinux.cfg and isolinux.msg file to syslinux.msg. This is not mandatory but makes more sense.

4. Now extract the syslinux archive previously downloaded and copy the syslinux.exe file from its win32 directory into the \boot\syslinux directory of the USB stick.

5. Modify the \boot\syslinux\syslinux.cfg: replace all isolinux.* appellations with syslinux.*.

...
kernel /boot/isolinux/ifmem.c32
...

to

...
kernel /boot/syslinux/ifmem.c32
...

display syslinux.msg
label slitaz
	kernel /boot/bzImage
	append initrd=/boot/rootfs.gz rw root=/dev/null lang=C kmap=uk vga=normal autologin

include common.cfg

Note : In the example above, compared to the original file, the line display isolinux.msg has been replaced by display syslinux.cfg and the parameters lang=C kmap=uk have been added to the line append so that, lang and keyboard are automatically selected at boot.

In file \boot\syslinux\common.cfg, modify

...
F3 isolinux.msg
...

to

...
F3 syslinux.msg
...

6. Now, from the terminal in Windows, run syslinux.exe to install the bootloader. For example, here the USB stick is shown as letter K, type:

k:
cd \boot\syslinux
syslinux -ma -d \boot\syslinux k:

7. You can now restart your computer. Change option in BIOS to boot first from USB.
