[Bug 1847047] Re: 19.10 Beta won't boot after grub

[Xtien]

I have a XPS 15 (7590),  Intel® Core™ i9-9980HK (16 MB cache, tot 5,0 GHz, 8 cores).
I installed Ubuntu 19.04, then upgraded when 19.10 became available. On Nov 18 there was a bios upgrade. This morning, the laptop wouldn't boot. I can type the disk password, than there's a flash and a black screen, and nothing. It's my work laptop, so I went home to use another computer, don't have time right now to see what's wrong. 
I'm planning to do a fresh install of 19.04 this weekend. Unless there's something else I can try.
