Hello.
I shrank the boot partitions of teo installed operating systems, and, for each thence created unallocated space, I created a new sext4 partition, to which, I assigned the respective labels Data05 and Data06. I then, from within my UbuntuMATE 16.04 installation, ran sudo chmod 777 on each new partition, so as to enable read+write access to the two partitions. But, I can not write to the two partitions. What do I need to further do, to these partitions, to enable read+write access?

Might they be mounted read-only? What is in your /etc/fstab? Have you done a reboot after you changed your partitions?

Otherwise-unprivileged processes on your system don't need the ability to write to the *device nodes*. I suspect what you wanted to do was to modify the permissions on the *mount points* instead.
