Why is Ubuntu stealing my megabytes when I partition my disk?

Question

ubuntu

During installation, during the partition of the disk, I first create a new partition table, first I create a UEFI partition with a size of 105 MB, so in the end it becomes 103 MB - for some reason 1 MB is separated and becomes a separate free area, and the second megabyte stupidly disappears. What the hell?

Answer 1

Section alignment + rounding on output

Answer 2

ubuntu steals space to give your personal data to aliens
