Only slightly related, but I once had a chromebook I was very happy about, until after a few years it just failed to boot. I've repaired many linux laptops in my life, usually using an USB key to boot a live system and fix the disk-drive or something. But with this chromebook, there was absolutely nothing I could do. No access to something like a DOS or anything, nothing booted from the USB port. Just a black screen.
I've never bought any chromebook since.
Was I just unlucky and should I git it an other try?
In short you need a pendrive and another computer with Chrome to to download a recovery image and flash the pendrive. Afterwards use a key combo on Chromebook and it should be fixed.
In my case it helped, but I retained this pendrive with instructions for my wife if it would happen again (and she managed). I had to skip updates for some time.
A lesson for me was to not buy an ARM Chromebook again.
Chromebooks have recovery mode. This is functionality in the firmware to reinstall the OS from a signed image on a USB drive or SD card (device obviously needs to have the SD card reader for this). Just look up instructions online for more details which will be better than anything I could write.
