I dual boot with Ubuntu. I have had no problem updating my system over the last 4 year (3 system updates).
I now need to update to Mojave and get the error message This disk cannot be used to start up your computer. when trying to update.
Would someone have a hint as to how I could do this without wiping out my Linux partition (as outlined in this thread)?
