At last I have completed the hardware upgrade of my machine: better processors, more and better memory, NVMe drive so ready to go but…
In the excitement of repartitioning and avoiding the need for an USB for booting I find that I have no swap partition. Here is what my machine looks like now:-

Note the Alert for no swap.
I do have plenty of memory but I recall reading that the absence of a swap partition can cause problems.
Should I ignore the alert of add it in?
If I add a swap partition where and is 2GB?
Budge.
