Create a Multiple OS boot drive usb - Windows, Linus and Mac

Multiple boot drives on a single usb

I am looking for an expert with boot records/drives, I have been trying for a long time to get windows and Mac OS installers booting from one usb, without success.

What I want, is to have Ventnoy installed on a USB, that has multiple versions of windows and Linux (multiple ISO’s).
Also on the same USB, multiple partitions, each with a MAC OS installer.

So from one USB, I can install any versions of Windows, Linux or Mac OS - subject to the size of the drive. (today I have two drives, one for Ventnoy and the other with multiple Mac OS’s - so I do not need your help with that option.)

I am sure an expert with boot drives can do this.

I will as a minimum have the following in Ventnoy
- Win 11
- Win 10
- Win 8.1
- Zorin 18
- Zorin 17 lite
- Ubuntu Desktop
- Ubuntu Desktop Arm

Plus partitions for the following Mac OS
- OS X 10.7 Lion (2011)
- OS X 10.8 Mountain Lion (2012)
- OS X 10.9 Mavericks (2013)
- OS X 10.10 Yosemite (2014)
- OS X 10.11 El Capitan (2015)
- macOS 10.12 Sierra (2016)
- macOS 10.13 High Sierra (2017)
- macOS 10.14 Mojave (2018)
- macOS 10.15 Catalina (2019)
- macOS 11 Big Sur (2020)
- macOS 12 Monterey (2021)
- macOS 13 Ventura (2022)
- macOS 14 Sonoma (2023)
- macOS 15 Sequoia (2024)

The usb will need to work in legacy and uefi systems.
When booting from the USB, i expect to select Ventnoy or any of the MAC os options. If I select Ventnoy, I would select the Windows or Linux OS front he Ventnoy menu.

If you are able to build this Multi boot USB, please let me know.

Any questions, please ask.
