I recently got my first RPi (4 model B 2GB) and a brand new SD card (Goconecto 1TB micro SD XC 3 A2). I'm trying to install Ubuntu Server via the net installer. Up to now I've tried 20.04 64bit, 22.04 32bit and 22.04 64bit. The installation seems to complete fine, but when it reboots I'm invariably greeted with the rainbow screen.
While trying to spot the problem, I tried a much smaller SD card, which didn't get stuck at the rainbow screen, but wasn't big enough and got stuck on the first update.
Nevertheless I've tested the Goconecto SD on other devices and it looks like it works fine as a simple storage device. Have I missed some SD compatibility guidelines?
