Installing Ubuntu-Mate 18.04 - what to do if the bootloader breaks

[alpinejohn]

Hallo

I’ve just upgraded my main system from 16.04 to 18.04. It was a fight. I have two drives and an Intel BIOS. When installing via “The something else method” the bootloader broke.

I was technically out of my depth, all I could get was a GRUB prompt.

Ubuntu-Mate solved the problem for me. Here is how that happened.

I then continued with the installation process which went smoothly (except for some difficulties with my QWERTZ keyboard (for details and solution see this post):

@mdooley It’s in Welcome > Installation guide > Dual booting and there you can Install it.

I only know it’s there, because I was translating Welcome and had to explore what it is to translate it correctly.

Ahh. I finally found it in a live USB (MATE 18.04.1) under Installation Help > Dual Booting > Repair Boot Problems > Download Boot Repair. Thanks ele.
