UEFI-boot FatDog (Puppy) linux from your Easy2Boot USB drive

FatDog (a 64-bit version of Puppy) now supports 64-bit UEFI booting. Here is how to add it to Easy2Boot and enable UEFI booting.

1. Download FatDog64-631.iso from here
2. Extract the contents of the ISO to a new empty folder on your Windows hard drive - e.g. C:\temp\fatdog631
3. Extract all the files from the efiboot.img file to the C:\temp\fatdog631 folder - you should now have a C:\temp\fatdog631\efi folder (amongst others)...

4. (optional) delete the [BOOT] folder if there is one and the efiboot.img file
5. Drag-and-drop the C:\temp\fatdog631 folder onto the Windows Desktop MPI_FAT32 shortcut to make a .imgPTN file (see - MakePartImage for details). if you want the persistence feature (Save file), increase the size of the FAT32 partition (e.g. add 500MB).

Note that if there is not enough space and Puppy creates a very small Save file, it will not boot until you delete the Save file!

6. Copy the .imgPTN file to your E2B USB drive's \_ISO\MAINMENU folder (or other menu folder)

You can now boot to E2B in the normal way and select the new .imgPTN file. Once you have switched partitions you can UEFI-boot from it (64-bit systems only) or use Clover to UEFI-boot directly or use the CSM menu to boot in MBR mode.

This is the first reFind UEFI boot screen

This is the next menu after pressing [ENTER]

Note: If you wish you can skip the reFind UEFI boot menu and also save some file space as follows (do this after step 4 above or in the partition image itself):

1. Delete all files and folders under the C:\temp\fatdog632\EFI\boot folder
2. Move the \EFI\grub2\grub2.efi file to the \EFI\boot folder
3. Rename the \EFI\boot\grub2.efi file to bootx64.efi

You should now have a single file under the \EFI folder called \EFI\boot\bootx64.efi. When you UEFI-boot, you will see the black menu screen shown above.

64-bit and 32-bit UEFI for Puppy ISOs

You can drag-and-drop the ISO onto the MPI_FAT32 shortcut to convert it to a .imgPTN file (choose 37 for linux option). I used tahr-6.0.6-uefi.iso. Don't forget to increase the default size suggested if you want to use the Save feature and have persistence.

Switch to the .imgPTN file and the FAT32 partition.

Now extract the contents of the \efi.img file to the root of the E2B drive (i.e. the new FAT32 partition should now contain \EFI\BOOT\BOOTX64.EFI).

Now it will be UEFI-64-bit bootable.

To add the 32-bit grub boot file, download http://distro.ibibli...2.00-i686-1.txz

Extract the \grub2-efi32-2.00-i686-1.txz\grub2-efi32-2.00-i686-1.tar\usr\share\grub2-efi\grubia32.efi file using 7Zip

Copy it to the \EFI\BOOT folder and rename it to bootia32.EFI, so you have now...

  • \EFI\BOOT\bootia32.efi
  • \EFI\BOOT\bootx64.efi
  • \grub.cfg (should already be present)
Now you should be able to UEFI 32-bit/64-bit and MBR boot.
