Thanks Nico_Paul. Sorry for the delayed response as it took some time to do everything suggested.
There is only one OS on the system using a single disk with 238.47 Gbytes according to gParted. The primary, first, and only OS is Parrot Security 4.4 64-bit.
balenaEtcher 1.4.9 x64 and x86 for Windows could not be downloaded on Windows using Firefox 64.0 32-bit but Chrome 71.0.3578.98 64-bit was successful. Although Virus Total gave the x64 and x86 versions a clean bill of health, metadefender.opswat.com reported that Filseclab found Adware.Domage.Neobar.BF.qpiw in a DLL. Accordingly I did not use any of them.
Many alternative USB writers are also reported as being virus-laden, many worse than balenaEtcher (Virus Total and Metadefender both reporting trojans, etc.). Others “clean” writers simply did not work, such as Microsoft’s Windows USB/DVD Download Tool which did not consider Parrot-security-4.4_amd64.iso a valid ISO. I finally used Rufus for Windows 10/8/7/XP release 3.4 (RufusPortable_3.4.paf.exe) from https://www.downloadrufus.com/ in FAT32 mode with a 4096 byte cluster size. Rufus under Windows is quite slow compared to balenaEtcher on Linux Mint.
First I booted from USB into Live mode and used gParted to erase all partitions from the single hard disk, executed Edit > Apply All Operations, then shut down.
Second I booted from USB into Live mode and created the following partitions in gParted:
ext4 /boot 1 Gbyte flags boot
ext4 / 32 Gbyte
linux-swap 4 Gbyte
ext4 /home 201.47 Gbyte
then executed Edit > Apply All Operations, then shut down.
Third I booted from USB again, and from the boot menu scrolled to the penultimate option Install near the bottom of the menu, but the options within were only {Standard Installer, Install with GTK GUI, Install with speech synthesis}. The final menu option was Advanced options, which only included Load system to RAM. So I booted into the Live mode and executed Menu > System Tools > Install Parrot. For Partition Disks I chose Manual and configured it as follows:
#1 use as: ext4; format the partition: yes, format it; mount point /boot; bootable flag: on;
#2 use as: ext4; format the partition: yes, format it; mount point /; bootable flag: off;
#3 use as: swap area; bootable flag: off;
#4 use as: ext4; format the partition: yes, format it; mount point /home; bootable flag: off;
then Finished Partitioning and write changes to disk, etc. After waiting for the entire system to install, the process finished with an error Grub installation failed. The ‘grub-pc’ package failed to install into /target/, etc. again. I did Go Back and then Abort the Installation.
Fourth I booted from a different USB created with a Linux x64 balenaEtcher 1.4.9 installed from their Debian repo with kali-linux-mate-2018.4-amd64.iso on it. In the boot menu I chose the Install option because Kail’s Graphical Install does not recognize the trackpad as a mouse on the Acer S3. I used the existing partitions created above with the same options. Kali had no issues installing the grub boot loader to the master boot record of /dev/sda, after which I shut down.
Fifth I booted from /dev/sda into the Kali root console boot as root and entered the startx command, which successfully brought up the Kali GUI environment (such that it is).
