Excellent! I am still using my 2015 Toshiba CB. It may go another couple years.
Oh, I put a much bigger 128gb SSD in mine too. The 4gb or 8gb it came with wouldn’t do, obviously.
Ya. I retired mine a long time ago. 4gb ram and 32 gb disk space is pretty futile. They want you to cloud!
It shows it’s supported on mrchromebox site.
Edit: I may try it or not because it’s a 360 2 in 1 with touch screen so there may be just too many issues with that. Although with the uefi firmware coreboot i could put Windows on it. 
If you flash firmware then ChromeOS won’t boot.
Looks like there is a new project on the block for Chromebook installs https://eupnea-linux.github.io/
EDIT: Looks like the previous link died. Here’s a working one with more info:

I have a Lenovo Yoga 360 or some such model (Pantheon model). I put Gallium on it, unplugged it, suspended it by closing the lid, I then opened it up and it was borked. 
I used SeaBIOS for my purposes, so no I didn’t disassemble it. Anyhow, Ctl-L no longer works.
I created a recovery disk using Google’s “linux_recovery.sh” script, but it isn’t working. Fails verification. Has anyone encountered that? We have NO Windows machines anymore, and using their recovery extension doesn’t work if you’re on Linux. Not sure where to go?
GalliumOS is very outdated, wouldn’t recommend using it.
Are you following this guide?
Thank you Chikenf00t! I’ll try that. No, I didn’t see that page. I’ll report back when I have a result. 
It’s an install for ChromeOS Flex which is pretty bare-bones but it’ll at least get you something functional until you decide what to do with it.
No worries! I tried that, and I get “this doesn’t contain chrome OS”. This chromebook wasn’t on the list of certified models - in fact it wasn’t there, period! I’m going to re-try the initial method - maybe something went south the first time around. Wouldn’t be the first time! 
Thank you! I WILL try this on my wife’s ultra-old chromebook 
EDIT: well phooey! My wife’s chromebook is old, and didn’t have the recovery utility. Since it’s out of support, I can’t install the utility, as I’d have to update the browser (which of course means updating ChromeOS I’m sure). Looks like these two chromebooks are heading to the recycling center. Probably for the best.

I had Seabios on my chromebook long time back, but updated it for mrchomebox’s build which was tons better.
Do check and make an attempt this way before you recycle those two chromebooks.

Goodness - I’d forgotten to update ya’ll. I’ll recycle the super old Chromebook (the one that can’t be updated anymore), because the battery’s gone too. I unplug it, it dies. So away it goes. Since my wife does everything in a browser, I was able to re-purpose the Chromebook by making a recovery tool using the CLI in linux. So the CB I was tinkering with is now happily running Chome OS and is being used by my wife. It’s updated until June of 2028. Good enough. My wife values battery life above all else; I bought her a laptop two years ago, and she was never crazy about the batt life on it. She “traded” that laptop for the Chromebook. So I know have two Lenovo lappies.
You might be able to find a battery on ebay. I got one there a year or so ago.
And even if my current CB w/Linux battery dies, I’ll probably still use it, plugged in mode. It gets to a login prompt in under 30 secs.
