I have an Acer Nitro AN515-51 laptop that I bought in 2018 at Best Buy Canada. I have tried several times now to update and install version 1903 on this laptop. It works, then while installing, the screen goes blank and the laptop says it is uninstalling the latest windows version 1903. Then I am back to 1809 version. I have been in touch with Microsoft and they have tried to help me, but this laptop just won't accept the update and install. Any ideas as to why or what I should do about this now? I am very upset that I can't get the latest Windows.
