I'm trying to install Ubuntu-MATE 18.04.4 on a new, empty, external standalone 1 terabyte SSD.
I have 2 other drives in my desktop workstation, so in the installer I selected "do not use" for the swap spaces on those drives.
I then selected to create an 8 GB swap space for the SSD as a "logical" or extended partition at the end of the SSD's empty space. (Since my desktop box has 8 GB of RAM.)
Then I set up one large primary partition for both "/" (root) and /home directories from "Beginning of space" using the ext4 filesystem.
I selected for the bootloader to be on "sde" which is the SSD.
But when I click on "Install now," the informational box that pops up says that the large primary partition will be partition 2, and that the 8 GB swap partition will be partition 5.
The installer wants partitions 1, 3 and 4 to be "unallocated space" partitions. Is this normal? I defined just 2 partitions. I don't understand why the installer wants to create five partitions on my SSD.
Since I want to understand what's going on with this, I did not go ahead with the install.
Can anyone shed light on what's going on here?
What would be "standard"? Seems like a lot of space is getting wasted with three "unallocated space" partitions. How would I correct this so as to limit the number of partitions and also not have unused or wasted space. Or do I want some small bit of free or unallocated space as, say, one partition?
Could I avoid all this if the first partition I create is the large / and home as primary, from the beginning of the space (leaving only 10 GB at the end), then, secondly, create the 8 GB swap space from "end of space" (or even from "beginning of space" which would be at the end of the primary partition, with 2 GB at the end - thoough maybe that would create a 3rd partition.)
Will I still end up with more than 2 partitions? Or rather, how can I do this to have only 2 (and is it ok to want just 2, or is there some need for a third partition to have "free space". Is there generally a need for free space with an SSD?
UPDATE: More info:
I tried to do this yesterday on a different SSD, and I did end up with what appeared to be extra partitions:
Partitions 1, 3 and 4 were "unallocated space" totaling about 40 or 50 GB of wasted space. I don't know why or how it happened like that.
Just a note about my situation: Failure for this install is not a good idea for me right now: My 16.04 drive broke and gives me a blank screen, so I'm working from an older 14.04 spinner (internal) HDD that is crashing on me every 10 minutes and it re-boots slowly, Hence I'm in a bit of a painful place.
(Also I'm supposed to be working from home right now, and they're starting to wonder what's up with me.)
So I'd like to get 18.04 up and running asap, and, for right now, I'll need to be able to boot from this new external 18.04 SSD that I'm trying to format and install right now.
Over the weekend or as soon as I can, I'll replace the internal 14.04 spinner with the new 18.04 SSD. Right now I need a working system.
