I have a Raspberry Pi 1 Model A and would like to install a *nix (probably either Raspbian or Ubuntu) OS to something (SD card, whatever) so that I only have to install it one time, and that the rpi simply needs to run that installed OS at startup.
How can I do this? I'm worried about a situation where I need to install the OS each and every time I give the rpi power!
Use the program Etcher with a so-called image file. All your settings , installed programs and documents will be saved if you do a proper shutdown from the "Start" menu (it is called something else on Raspbian , but you get the idea).
Get image files for "Raspbian Stretch Desktop ZIP" here . I strongly recommend Raspbian , it is the best supported distro and the Model 1 A can not run Ubuntu anyway.
