GRUB4DOS 0.4.5c 2013-07-24, root is (0x80,0)
Processing the preset-menu ...

The reporter was not aware of having done wrong with the preset-menu. I suppose  the preset menu might have a line like find --set-root without the --ignore-floppies switch, or explicitly use (fd0), or made another mistake that causes infinit loop, etc.

What is your menu.lst?
If you have the original menu.lst , I have to correct a mistake!

Grub4dos working for me.
Thanks for helping me

I do not have any PC available with a floppy disk drive to reproduce.
Anyway,I removed the option menu Floppy (fd0) in scripts "Create ISO" and "Copy to USB". I do not think it is really useful.
The option "Add the contents of this file after WinPESE in grub4dos'  menu.lst:" is available, if needed.
The scripts are on the server.
Thanks for the return
