> The "Reserved" partition on Windows machines isn't really a boot partition, for any meaningful definition of it. It's just … reserved, and MS being MS. On my machine, it's empty (unformatted, all 0s). It is lightly documented here: https://learn.microsoft.com/en-us/windows-hardware/manufactu...
IIRC, that "reserved" partition is to allow converting the data partition which follows it to a "dynamic disk" (which AFAIK, is Microsoft's equivalent to a Linux LVM PV). That conversion needs to grow the partition backwards to prepend some headers, and that extra space comes from shrinking the reserved partition just before it.
