I have installed Cubocore on my Lenovo T450s. So far, so good. I did the first update and suddenly the laptop would only boot as far as showing
Loading initial ramdisk
I could still boot the machine using one of the backup images. Today I updated one of those images and now nothing boots.
So, what do I do? The easy way out is to re-install but what do I learn from that? Nothing!! I'd like to try and sort out why the initial update borked it so that I can fix it. Problem is - I have no way of posting anything much in the way of output/logs etc from the machine.
