I am talking about this special feature of booting within an iso image.
The "secrets" of using isolinux are an additional part.

Sorry - no it does not.
I was talking about the file FreeDOS_1.1.iso.
Where did you get this 2 iso files?
Why you can boot them without a loopback?
But this method is working now and i can understand why:
menuentry "FreeDOS ISO Image Isolinux" {
set isofile="/boot/iso/FreeDOS_1.1.iso"
loopback loop (hd0,1)$isofile
linux16 (loop)/ISOLINUX/MEMDISK
initrd16 (loop)/ISOLINUX/FDBOOT.IMG
}
With use of loopback i am mounting the iso file.
Then both files within the iso are loaded and executed.
FreeDOS 1.1 is starting, but then it can't work with the files within the ISO.
So i get the message: "SETUP wasn't able to locate any disks to install FreeDOS
1.1 from"
Now some new mystic things has happened.
The file i have used has disappeared from the download page.
http://www.freedos.org/download/
They are talking about a LiveCD, but there is no download for it?
I googled for it, but found this one instead:

Up to now i could not boot this image with grub ...
Cheers
