Flash-drive Installation Method for UEFI Boot
This page explains the method and steps to
make a bootable flashdrive suitable for booting on UEFI systems.
It assumes that you have booted into Fatdog and you have a copy
of the ISO file handy, or you have followed a simplified installation method
(in other words, you have a copy of the files from Fatdog
Firstly you must ensure that you have access to the Fatdog
installation files. They are:
You can find these files inside Fatdog ISO distribution file; you
can get access to these files by:
- Burning the ISO to a CD/DVD and you can access them by
inserting it to you CD/DVD reader
- Opening the ISO file directly from inside Fatdog (click or
double-click on it)
- dd-ing the ISO file to a flash drive
using simplified installation
and inserting the flash drive to your USB port.
Make sure your flash drive has a FAT32 partition, and it
is large enough (512M or more) to hold copies of Fatdog files.
Some UEFI firmware accepts FAT16 too but the official standard
requires FAT32. Most flash drives today ship with FAT32
factory-formatted so you usually don't even need to do this, but
it is always good to check and confirm.
Name your partition as "FATDOG_LIVE". Use dosfslabel
from terminal to do this.
Most UEFI firmware will accept any partition type if you
use MBR partition. Some stricter ones don't; and in this case you
need to set the partition type to type EF.
If you find that your flash drive is not listed ignored or not
recognised by the UEFI firmware boot menu, this may be the case:
from terminal to do change the partition type as
Note: If you use GPT partition then the partition type must
be set to EF00. Use gdisk
to do this.
Do the previous steps above while your partition is *not*
mounted. When done, mount your FAT32 partition (just click the
drive icon from your desktop).
Copy vmlinuz, initrd, grub.cfg and fatdog.png from
Fatdog ISO/CD/DVD/flash drive to this FAT32 partition.
Open terminal and cd to the path that contains the file
efiboot.img. Then type "filemnt efiboot.img". A Rox window will
appear. Do not close the terminal window.
Copy all the files from this window to your FAT32
Type "filemnt efiboot.img" once again on the same
terminal that you did step 6. The rox window should close.
That's it! Unmount your flash drive and you're ready to boot. If
you're feeling adventurous, you can go on and create additional
partitions (e.g. ext4 or f2fs) on your flash drive for you to put
your savefile/savedir there. You can also edit grub.cfg
meet your needs (e.g. adding boot parameters, removing unnecessary
Yet another alternate method
If you feel that the above steps are too complicated, Puppy Linux
forum member Ted Dog has prepared a ZIP file that contains
pre-packaged boot files extracted from efiboot.img.
All you need to do is:
download the ZIP file, extract
the content of the ZIP file to that your flash drive, and copy
over Fatdog64 ISO file there too. The complete steps and the links
to the ZIP file can be found here
The same method can be re-used to boot other Puppy Linux variants
Forum member cat&dog has alternate instructions based on Ted
Dog's method that works for him, here
Note 1: If you follow these methods, you do not need to run fix-usb.sh
in fact doing so will ruin your flash drive partitioning; so don't
Note 2: All the configuration files produced by this method is
editable. Actually all files are editable.
Note 3: Since this uses standard partition table, Gparted should
be able to modify it as usual.
