I've just installed Ubuntu on a new SSD along with a HDD for data.
Strangely, when I divided partitions at install, 1MB of non-removable free space was reserved at the beginning of each disk. I ignored them however, because I thought they wouldn't be a problem.
But after install, when I sudo fdisk -l
, I get the following warnings:

I have little knowledge on GPT/GUIDs, but I'm guessing that the warnings were caused because of the 1MBs at the installation stage.
So here are my questions:
- Can the warning be a potential problem, issue or difficulty in the future?
- Is there a smart & safe way to fix the warning?
