(1) If you are happy with 1909, the best thing to do is a new clean installto get all the partitions right. Currently, you've got...
(a) An empty leftover Win 8.1 recovery partition.
(b) An EFI partition shared by 1809 & 1909.
(c) An MSR partition probably used by 1809 only.
(d) An 1809 Windows partition that is highly dysfunctional.
(e) A 1909 Windows partition (named Local Disk) that has its recovery environment in a folder.
(f) An 1809 recovery partition.
(g) A Win 8.1 factory reinstall partition.
That's a big mess & waste of space. We could probably clean it up dangerously with AOMEI -- but a clean install really is best. You've got that first system image to get you back in shape, if something goes really wrong -- but I doubt it will. We know 1909
can clean install well for you.
Remember, version 2004 is coming soon. We don't know what it will think of that big mess or the smaller one AOMEI is likely to leave.
(2) Let me see what Windows system image offers to you...
Mine are all pre-selected & cannot be checked/unchecked. You will want EFI (it's shared). MSR doesn't show up there. The WinRE it offers or pre-selects belongs to 1809, but at least it's tiny & won't hurt 1909. Yeah, may as well make one without the 1809
partition (D:). Then name it "Messy_1909".
