Re: W10
I suspect Microsoft code for MBR Partition Table mgmt was (and probably still is) broken, so that when you have extended partitions not in physical order, some of them are just being lost in the process of updating / rewriting an MBR Partition Table.
That happened at least to me. Ubuntu (on my multiboot machine) created own extended partitions this way (and saved on one physical disk sector). After upgrading w7 to w10, Ubuntu was gone off my machine. I restored the PT by hand and repeated the process several times to prove there is a bug in MS code. I have recorded this on video too (though still unereleased).
I am sad to see it is so hard to make M$ remunerating for bisheaviour of their software.
Should that have happen with ReactOS (https://twitter.com/reactos), it would be acceptable for me because they are software still in alpha. Plus, they are free to install.
