Hi, recently my wifes Lenovo Z585(AMD APU and GPU) got the superb Windows 10 1803 update and rendered it useless.
With Rufus I created a bootalbe ISO based on 1803, downloaded with Microsoft Media Creation tool.
I managed to reinstall it(MBR Partition scheme), but under installation the screen was completely black! Only managed to read the screen with a flashlight. After boot, Win10 installed KB4284835 update which was supposed to fix the black screen issue. It did not. Just got worse. It won't even boot now.
Tried to boot from a USB Windows 7 ISO. Still have the black screen, barely visible only with my phones flash.
Now I removed the HDD and USB stick, but it still can't go to BIOS. If I remove AC Power and battery, sometimes after 30-60 minutes it boots and I can enter BIOS, or install Windows, but always goes back to back screen.
Is this an issue with the notebook, or Windows? I don't know how to solve it now. BIOS version is 60CN97WW, the newest as far as I know.
Can someone help, please?

I read that this may be related to an overheating issue. So I cleaned the internals and applied thermal paste to the GPU and CPU. It is much more quite, and much less hot. But still, without anything connected, I can only enter the BIOS, once in about 30 minutes.
