First in-the-wild UEFI bootkit bypassing UEFI Secure Boot
The write-up I saw suggests that revoking the Windows bootloader would cause existing install and restore images to fail to boot even with Secure Boot disabled because it checks its own signature, which would be pretty amazing if true: https://github.com/Wack0/CVE-2022-21894

Tools for Linux Distro Hoppers
Ventoy is an open-source tool to create a bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. Using Ventoy, we can create live USB for multiple distros in one flash disk. This is a revolutionary feature compared to other tools, e.g., Etcher, Rufus, etc, that can only create one live USB at a time. This tool is so important. Don't call yourself a distro hopper if you don't know this tool.

I'm thinking you mean Ventoy? They say they can load vhd and img files, though I've only tried ISO's myself.

How to Boot ISO Files from GRUB2 Boot Loader
> While this works, I find this method a bit tedious to use, at least compared to Ventoy [0].
I find ventoy more tedious, because you can't use it on your hard drive with a sane partitioning scheme.
The only reason is because of how the ventoy detection hardcode the partition boundaries in its checks, and it means Ventoy can only run with the partitions set in a way that may lead to alignment issues like write-amplification: I've detailed that in https://github.com/ventoy/Ventoy/issues/1342
Ideally I'd have a 10G partition after the EFI (or it could even be the EFI itself) with a few ISOs for rescue purposes + a UEFI entry to avoid having to use a bootable USB, but that's not possible with Ventoy unless I accept Ventoy choices of partition boundaries:

Booting from a bootable USB flash stick?
I downloaded and made a bootable USB Ventoy (https://www.ventoy.net) with its Windows GUI app in my updated 64-bit W10 Pro PC. However, I couldn't seem to get VirtualBox v7.0.12 to boot it. I read VirtualBox can boot from bootable USB flash sticks so it should work. Am I missing something?

Attempt Q4OS install on Netbook, BUT "unable to install grub in /dev/sda"...solutions?
So, yes. The installer will need to install grub to that first partition. You can install ventoy to a usb drive, put a windows iso there and your q4os iso. In case you mess up big time, you can reinstall windows.
