As predicted, attempting to install a 2nd distro on laptop #1 has resulted in a complete and total system failure I somehow managed to go from a 2 OS system to a system that I can't even get a base system installed and running! I haven't given up (well I have for tonight) but I am starting to wonder - how can I know if the problem isn't with the computer itself? Since I bought this laptop (new) I have struggled to get a working system in place - I thought it was the Nvidia card but now I am really starting wonder if it is one of the hard drives or something else? Any thoughts on how I could diagnose?I'll pick up and run with this one.
Jeffrey, this would be a good time to start labelling partitions, in particular your / partition, with the name of the Distro, do it in Jeffrey-friendly terms eg LM19-Cinn
Note I say label, not Name.
Note what Capta (@CptCharis ) said here, at #2 https://www.linux.org/threads/question-about-partitioning-sdd-after-os-is-installed.19701/#post-58426 ... which said, in part
... my highlighting.
When I suggested your setting up a Timeshift partition and a Data partition on your hard drive, /dev/sda, and labelling them, you set up the partitions and named them.
No harm, but not as useful.
The labelling field does not allow as many characters as the name partition field, it might be 14 - 16, but a bonus is that that label then appears in your File Managers, and it makes it easier for us to read which Distros are which, with their /'s.
Example from my Caja FM under Ubuntu 18.04.1 'Bionic Beaver' MATE:

Note straight away how easy (for me) it makes to see what Distros I gave on, and with abbreviations such as HDD, SSD, and WD for the Western Digital My Book ... where they are
For the entries that say Ex-Adata-1 and 2wayAdataDocs, yours might read DATA.
For the ones that read 21GB volume, I often use "DistroReady", meaning I will install one there, and it will be the Distro's /
The 2 x Timeshift is simply indicative of my first setting up a 100 GB space on the HDD /dev/sda, before then setting up a 400 GB one on the WD external. One will be migrated to the other, perhaps.
If you could go ahead and do that with both your /dev/sda and /dev/sdb, it would help you and us.
All of this comes via GParted, and you will see the extra fields generated as you perform the operation.
Haha, yes sometimes I am awake during normal daytime hours! I did it from LM (which I sense was the WRONG thing to do?)Hhmmm ... while I was sleeping
Was the attempt to resize MJRO being performed under GParted from a Live Medium or from Tara Cinnamon on /dev/sda?
