I have a KODi installation on the SD card and now I'm interested in overriding the SD card with another OS installation downloaded as ZIP. This sounds pretty easy but I'm using a Windows 10 device so several parts are only avilable seperatly or just not displayed.
Your question is not clear. Specifically:
- "overriding the SD card"
---->over-writing the SD card ??
- "several parts are only avilable seperatly or just not displayed"
I will guess that you want to write a new image to your SD card using Windows. If that's not correct, my apologies for wasting your time. Here's one way to write a new image to your SD card:
You must un-zip (decompress) your zip file. There are Windows programs that do that - find one, and use it. Do not ask how to do that here.
When you have un-zipped the zip file, there should be an image file; for example,
2021-01-11-raspios-buster-armhf-lite.img. You will now write, or "flash" this image file to your SD card.
You will need a program on Windows that is capable of writing an image file to your SD card.
rufusis one such program.
Once you have the SD card inserted, use
rufusto write your image file to the SD card. Afterwards, replace the SD card into your RPi, and apply power to boot.
