Install OS to Raspberry Pi5:30
The process of installing Operating system on raspberry Pi is changed.
Now the only way to install OS is using the Raspberry Pi OS image as shown in this video.
The next 2 Videos are optional now, and kept here for just understanding all ways. I still recommend going through all videos to keep a clear understanding of the process.

I have also uploaded the most recent video of installing OS to Raspberry Pi 5 without even using a monitor [2024]. I'd urge you to directly jump there and skip all videos. If you don't want me to keep old videos for reference, please post me a message and I'll delete them

Keep experimenting!!!
