How to write OS without assembler?

Question

Operating Systems

I want to write a console that will output:

"Hello world!"

What could be put on a PC or on a VM and at least it worked.
I want to write without Assembler, but if it’s impossible, and it’s definitely impossible, then at least output:

"Hello world!"

And at least with the help of C or C ++ (I don’t remember exactly).
And please, as little Assembler as possible.
Thank you very much in advance, but only for good answers and comments.

Answer 1

Yes, it's easy, you take an old floppy disk. There is a bootloader in the zero sector, it has only 512 bytes. So, in the absence of system files, he writes to a floppy disk, System is missingor something like that. You change this inscription in the hex editor to Hello, world!- Profit!
You don't need to know any programming languages.

Answer 2

Impossible.
In any case, you need to initialize the input and output devices, which cannot be done on a bare Sishka.
By the way, it would be easier to do your task specifically in Assembler, lol.
