Interesting. Looks like perhaps your boot loader isn’t properly pointing at your root partition.
I’m assuming you’ve just done the install and never successfully booted, yes? In that case, you can try to re-run the installer, or try rescue mode and try repairing the bootloader.
Are you doing dual-booting, or is this system dedicated to Linux?
I’m indifferent to them. I use their products, but I’m not a huge fan. I use them because I dislike the alternatives more.
I’ve been considering trying to degoogle myself, but honestly it would be complicated, and there’s a wife-approval factor that likely hinders that. We have multiple Chromecasts, Next hubs, etc around the house, and my wife likes the ease of use. I am slowly building up a home assistant instance, but still tying it into the Google home integration for ease of wife approval.
I use what works best for me, and right now most of those options are from Google.
