Universal EFI Matryoshka - ventoy.vhd - for lazy - for easy booting of many OS

Previously, I skeptically referred to all loaders - add-ons over Grub. But was asked to boot ventoy from AIO.
I reviewed a bunch of sites - but nothing was found - other than the installation of ventoy on the entire disk with its formatting.
 
I "booted"  ventoy with AIO.  Long searching in the network - how to change the ventoy "Standard Device".  Without this - ventoy does not open the download window.

But I have not found anything. There everything is - to install ventoy on the entire disk.

And a simple idea came - that I have not met in the network.
Installing ventoy in ventoy.vhd, format in NTFS and the necessary plugins - and a universal bootloader without a flash drive - with fast booting from disk
We load and boot the system from memory, or simply "map ventoy.vhd hd"  and run the system from the disk without loading to memory
 
We load ventoy.vhd  to memory - as usual with Grub4dos_uefi

title map --mem --top *.vhd  
set vhd=ventoy_3gb.vhd
find --set-root --devices=h /%vhd%
echo === %vhd%  will be loaded to RAM
ls dev
map --mem --top /%vhd% (hd)
ls dev
chainloader (hd-1)

But on my old 2010 computer Core i3 370  without EFI
 0).   EFI  is loaded from files.
 1).   (hd-1)  - does not work.   I boot  (hd1)+
(hd-1) ~ good operates with a new disk, and (hdx) +  must be pre-guess what you will have.

 

Here  ventoy_3gb.vhd  with  w11Ent348Drey.vhd  inside:
