boot - Windows 10 update killed grub, basic repair failed

I had an update on Windows and since then grub fails to load.


First I got into Ubuntu using the advanced start-up options and ran boot-repair. Didn't help


Second I tried reinstalling Ubuntu and restoring Windows to the original configuration (they needed cleaning up anyway). Grub still failed to load on startup.


Looking in the BIOS my boot order has various devices, Network and OS Boot Manager, I've tried putitng all of them first but grub still doesn't load.


Then I ran out of ideas. I saw this reply, but it's 4 years old. Is it still valid? (am scared of bricking my laptop)


Attached screenshots of my partitions, there are Windows partitions, one for my files, and one for Ubuntu. Grub is installed on sda. The one called RECOVERY I don't know what it is, I'm sure it wasn't there before.
