I don’t find this surprising at all. So many windows updates broke dual booting over years. They really don’t care and have no need to.
I think they dont care on purpose. Dual boot is a gateway drug, so the more problems with it the better for Microsoft.
And to the surprise of nobody at all, it’s related to SecureBoot, Microsoft said it won’t affect Linux distros and it did, and Microsoft has, of course, not yet commented on why distros like Ubuntu 24.04, arguably one of the most popular and common distros in the world, was not tested for this, even though M$ said that, 1. Linux Dual boots will not have the update applied, and 2. It warned that devices running older versions of Linux might experience problems
This is a pile of shit, not matter how you cut it. It’s Microcrap’s shitpile, and I hope I never have to interact with that thing again (a fool’s hope, but a hope nonetheless).
