Raspberry Pi Zero W not booting with a pre-installed SD card?

Hi there, I purchased a Raspberry Pi Zero W starter kit from The Pi Hut which came with a pre-installed OS on a SD card. However when I try to boot all I get is a rainbow screen and 7 blinking green flashes. Apparently the flashes mean "Kernel image not found" but as I say it's a pre-installed card that came with it so it seems unlikely the OS is installed wrong. Any help would be much appreciated! 🙏

Reflash it

Alright, I'll try

If you get a message from the Pi, then trust it because you can't argue with the Pi that you bought a SD card that is working.

I just tried a new SD card with a fresh install and it worked fine - so much for the ease of buying pre-installed lol

Thanks guys 👍

Most plp is happy with bought pre installed SD cards, but as everything there is a small percentage that will be faulty. Nothing is 100%.

Yup
