I used Neon for months, and in the last days (I always keep the system up to date) after restarting my system it didn't start anymore. A screen appears that asks you to select a system to start, when i select it starts a black screen where it is not possible to do anything or even open the terminal mode. I reinstalled it once and managed to use the computer for a day until the same problem happened again. I tried to reinstall again today and now it doesn't even install. Attached is the photo of the screen that asks to select the system and the black screen. Note: I am using a Lenovo Thinkpad T430u
