How to see an update error on windows 10?

Question

Windows

When installing (updating to) build 10240 after 2 reboots, the computer freezes with a black screen. After reset through the button, the current build is restored. All third party hardware is disabled. The system is on ssd, data is on hdd.
Thank you!
UPD: Yesterday, after the last attempt, the build was still installed. But the question is still relevant.
