Basic Question about Win 10 (or 11) install via USB

[Caveman]

Building a new system. Can anything else be on the USB other than the OS? Can I make the OS first and then install things like my MoBo, GPU drivers etc on the same USB drive (in a folder called "Drivers", etc) or must the OS installation USB ONLY contain the folders and files for the OS ("uncorrupted" by other files)?

It's fine to make a folder and copy anything you like there, windows installation doesn't care.

It's just a standard USB drive that is bootable. Still uses Windows file system. You can put anything you want on it. I put drivers and other programs on mine so they are available right away.

Just don't replace or modify any existing files and directories, unless you know what you are doing. Actually you can replace or modify some files without breaking digital signing or other integrity checks but a lot of them you cannot.
