New dumb user needs help with "Operatig system not found"

[Valerii]

Hello everyone
I need to use linux for the first time, to repair something in stupid windows
I standartly downloaded tiny core with visual environment, that jas weight 20+ MB, сant look now and remamber exaclty, put files from iso on usb, and booted from usb, having that there is no OS on usb, and there is nothing to boot

Sorry for such a dumb question, but i searched everywhere, but still could not find how to start ><

How to boot os from usb, without installing it, to just operate with files on disk without windows interfere? How to get started?
I will be extremely helpful to you if you help (i never used linux before)
