Recently I encountered the problem of creating a multiboot flash device: I needed different operating systems on one usb. There was a way out to buy another flash drive, which I will definitely do next time, but I was too lazy to go out and go get it and I read that doing this on one device is quite possible.
When I encountered difficulties, I registered on this wonderful forum and want to do something like a brief review of the programs that I used. I would like to take this opportunity to thank the forum members who helped me here - you are awesome, thank you for your responsiveness.
So, I used two programs: Winusb and Ventoy.
What can we say about WinUSB?
The program has a simple design, the process of creating a bootable USB drive is as simple as selecting the source and destination. The interface is spartan and simple, so even users with minimal technical experience like myself will be able to navigate without difficulty. One of the advantages I would like to note is that you can createundefined Bootable USB drive without the need to format the file system. WinUSB specializes in Windows OS, although it is stated that it supports Linux, but I personally encountered compatibility problems

Now about Ventoy
Ventoy allows you to download multiple ISO files from a single USB drive, which is what I needed. This happens without the need for extraction or special processing of each of them Ventoy is not limited to just Windows systems; there are a lot of supported distributions there. The interface and setting options are a little more complex than Winusb, but the drag and drop of ISO files when creating ISO images gives it the advantage. Ventoy worked with files an order of magnitude longer than Winusb.

As a result, I can say that Ventoy coped with my task of installing different OSes from one device. Winusb is also a good tool, faster, but I recommend using it only when working with Windows.
