Multiboot (GRUB 2) Rescue USB-Stick
With the Rescue Media Builder I’ve build a Linux-based ISO file. I took this ISO-file and created a bootable USB-stick. (with Rufus. Yes, I know that I could build the USB stick directly from the Media Builder, but I wanted to have the ISO too). This stick is working perfectly.
Now I wanted to prepare a multiboot USB-stick using Grub 2 with the ISO image mentioned above. I followed several hints from the internet, but nothing worked. Is there anybody who can explain to me, what the entries in the grub.cfg file have to look like to start the main menu of the rescue builder?

Thank you Steve,
I alread found and tried the same code what you suggested, however it doesn't work. I get the error messages
no such partition
you need to lead the kernel first
you need to lead the kernel first
Press any key to continue....
I f I enter the instructions manually I'm getting the error "no such partition" right after the linux.....-comand.
The same is true, when I change (loop,msdos1) to (hd0,msdos1) which holds the iso file.
BTW, my boot device is an SD-card which the system assigns to hd0. And yes, if I open the iso-file with WIN10, the dat10.dat, dat11.dat and dat12.dat files are in the file.

Wilfried, please take a look at forum topic: PXE Boot Possible? which uses a similar approach as needed for using Grub2 and has further examples that users have got working.
