Black scree after upgrading from 34 to 35

I have succesfuly upgraded my Thinkpad from 34 to 35, but I have some problems with my partners HP Envy x360 13˝. Everything went nice, the download and the installation. Just after the installation of the upgrade, computer turned the fans to max and screen turned black. I waited for 10 minutes and after that I turned the computer off. When I turn it on it’s just black screen. No logo whatsoever, nothing.
Any idea how to fix this?


edit: if I press esc at the startup and then F11 (System recovery), it boots normaly. The fan is on max al the time, but at least I can get into the system.

ps. hardware is Ryzen 5 3500U.
