Just having a chat with Steve here, as he mentionned that he has Ubuntu and Windoze dual boot on his PC, laptop and so forth, and apparently there was a problem with an older kernel whereby it would screw up access to the windows installation unless you gave it a couple of commands when installing. He doesn't think it should apply to 5.10, though, and suggests a quick trip to the forums to see what people have been discussing.

Not a great deal of help, I know.
