@ teckk:-
The guy's been asking this same question over on the Puppy Forums at Murga-linux, under a different user-name. He won't give the necessary information over there, either.
One of these who seem to think we all use crystal balls, and can guess what's going on in his head.....
FWIW, Puppy uses a custom Grub4DOS for a bootloader - based on the old 'legacy' GRUB. But where the 'official' Grub4DOS hasn't been maintained for some time, Pup's is a highly-customized version that
is regularly maintained & updated by the Woof-CE team at Github.
The last major update was around 7 months ago, to fix a long-standing problem Pup has had with booting from an EXT4 file-system, when it's been created by a 64-bit OS.....
'Puppians' almost exclusively use EXT3, y'see.
