Do not remember putting boot on sdb2. 
sdb5 = backup place for timeshift
sdb6 = /
sdb7 = /home

Sometime within the last few weeks, I made a live USB of mint cinnamon 19.3 using Unetbootin.  I installed that entirely on the / partition and did not create a /home partition and had not yet created a backup partition.  I wanted to see if copying some of the files from my old home directory would work in the mint install home folder.  Did not seem to work, so I axed that project and timeshifted back to 4.8.  The mint install did not have any issues booting up.
