Windows 10: Is a Recovery Drive and an .iso file the same?

Right after getting this computer, which came with Windows 10, I created a Recovery Drive. I forgot how I even did it, but when I plug it (the USB drive) into a USB port and read it, it shows several files and folders. This is supposed to get me back in the game if my computer suddenly lost its operating system, I guess.

However, I recently upgraded to version 1903 by downloading the .iso file for it and running the installation process. When I click the .iso file, it shows several files and folders just like my Recovery Drive does. Now I'm thinking that if my HDD crashed and I lost everything, and then I used my Recovery Drive as it is now, I'd be installing a much earlier version of Windows 10. Could I just erase what's on the R.D. right now and replace it with the .iso file for version 1903? Then I'd be getting something more recent when I did the recovery rather than a very early version which I'd then have to upgrade to afterwards.

There's one small difference that makes me question the idea. Like I said, when the Recovery Drive is plugged in and read, it immediately shows those files and folders. OTOH, with the .iso file, I have to click on the file in order to display those things. I'm thinking maybe the Recovery Drive as it is right now is configured in a way that automatically installs the OS since a computer with no OS in the first place wouldn't allow me to click on anything. Is this correct?

Bootable USB with ISO - What am I missing?

Have you copied all the files from the ISO to the flash drive? I can't see that step.


After step 10. (after formatting and making it the active partition)

Copy files from the ISO to flash drive.

Open CMD as administrator.

navigate to the flash drive, lets call it drive Z and type in the following commands.
Z:
cd boot
bootsect.exe /nt60 z:
exit


Then try again.
