I've attached a boot recording - all went smoothly this time. I trimmed it down to just the boot log itself. It may look like I cut off the start of the log, but I didn't. I have the complete file, though, if needed, including what happens after the boot (not much visibly). If it's not clear enough or you think I've missed something you need at the top or bottom of the screen, I can have another go.
