OS: Ubuntu 18.04 LTS, with Linux 4.15.0-1087-oem.
Notebook model: DELL LATITUDE 7400. No discrete video card.
The problem appeared suddenly and recently, probably after a system update. First, the loader window appears, I press Enter on the Ubuntu item - the download does not go, but sometimes it loaded without problems. I did all the manipulations with the parameters: neither
nomodeset nor others help. Now it doesn't start at all. All loader parameters are in their original state.
During these "black screens" the notebook starts to get very warm.
Edited the loader configuration file
Updated the loader. Checking information about the current kernel (kernel release):
$ uname -r 4.15.0-1080-oem
So now 4.15.0-1080-oem is loaded by default. But that's half the case. There is some serious problem with the latest boot-loaders (4.15.0-1087-oem & 4.15.0-1081-oem) - an obvious bug, there are fresh posts about it in the web... And how to solve this problem?
Maybe you just need to wait for the error to be fixed, and don't update the system until then?
