I want to use an old SD card 16MB to boot the image of a 1.44MB floppy disk with USB drivers using G4D.

What am I doing:

• I fill the Bootice card with zeros
• Using USB Disk Storage Format format in FAT
• Using Grub4Dos Installer 1.1 I install G4D
• Copy files: grldr, menu.lst and dos.img in the images directory

I test in Qemu and I have this:

 

How to correctly install G4D on the 16MB SD card?

menu.lst ???

As Steve just pointed out without knowing the contents of your menu.lst it will be difficult to understand where the issue is.

 

As always it is strongly advised - when experimenting - to issue commands one by one to be able to see which one creates the error.

 

From what I can see the issue is with the floppy image BPB (I poresume after you mapped the and hooked the floppy image).

 

As a side note, any reason to use the specific grub4dos build 0.4.5c 2014-01-17?

map --mem /images/dos.img (fd0)
map --hook
chainloader (fd0)+1
rootnoverify (fd0)

With the latest version is the same.

# map payload as large fd and first internal hdd as hd0 only
map %ISOC% (fd0) || map --mem %ISOC% (fd0)
map --hook
set A=
if exist (fd0)/IO.SYS set A=1
if exist (fd0)/KERNEL.SYS set A=1
if not exist A set /p A=WARNING: IO.SYS or KERNEL.SYS boot files not in image file!
set A=
errorcheck off
map (hd1) (hd0)
map --hook
#set just one HDD and one floppy
map --harddrives=1
map --floppies=1
root (fd0)
chainloader /IO.SYS || chainloader /KERNEL.SYS || chainloader (fd0)+1
boot

where %ISOC% is the path of the file

Everything works. It starts a bit longer but it works. I made everything again from the beginning, i.e: zero, replug stick, USB format, install G4D, copy files

I do not know what was wrong.
