I have been running Ubuntu alongside windows 10, but a recent update removed the grub loader.
I tried using Boot Repair as suggest by this post: grub rescue> during windows 10 update
But it's repair made things worse. Now on startup I get the message: BOOTMGR missing.
I have tried fiddling with Bootrec /RebuildBcd as suggested here: https://support.microsoft.com/en-us/kb/2622803
but I get nowhere and I don't know what I'm doing. Any help is greatly appreciated!
Here is the Boot Repair's report: http://paste.ubuntu.com/13637524/
Update: Working from a live Ubuntu CD I can't seem to mount my Ubuntu partition because it no longer has a filesystem?
