How to MBR-boot to Ventoy from grub2 - Steve2926 - 08-28-2020

If ventoy grub2 boot code is not installed to the USB drive, how can I boot to Ventoy from another grub2 menu as there is no Ventoy core.img file present?

i.e.
  1. Prepare USB drive with partition 1 and partition 2
  2. standard grub2 is installed on USB drive
  3. copy ventoy files from a ventoy USB drive to partition 2
  4. MBR-boot to standard grub2 menu
  5. Choose a grub2 menu entry to boot to Ventoy MBR grub2 on the second partition

if I get core.img.xz and extract core.img and use
multiboot (hd0,2)/ventoy/core.img
it hangs.

I would really like to be able to boot Legacy Ventoy from grub4dos and/or from legacy grub2.
This means I can add Ventoy to an existing bootable USB drive.
I just need Ventoy to contain a bootable i386-pc core.img file or a g2ldr file.
e.g. 
kernel /ventoy/g2ldr

or


root (hd0,2)
kernel /ventoy/core.img

If anyone who has tested this successfully would summarize in a step-by-step manner, I'm sure it would be much appreciated by the community -- and me among them. Smile
