I have backed off even further and have switched from the dual boot on an SSD to MATE installation on a normal HD. Maybe this should be a new topic, if any of you think so please move it; since I do not know how to do that.
I built my install USB with unetbootin (previously using rufus) used the i386 version because the nx6325 can only use 2.87GB of the 4GB ram. (Apparent bug in the BIOS, which they never fixed.)
Everything went according to plan (I did not do any additional partitioning) as I let the program handle the whole thing. BUT, when I got to the time to reboot to use your new system, it shut down with the power light and the sound off LEDs illuminated, as well as the hard drive spinning and the fan occasionally turning on to cool the system.
I went to the Magic SysRq key set as instructed by @ouroumov previously and it would not respond to any of the commands. I tried p, t and o both with and without the blue Fn key held down, always holding Alt and SysRq keys. So I gave up and held down the power key until it turned off.
I started it back up and it has been constantly accessing the HD with a black screen. It has been doing that the whole time I have been entering this message.
Then I restarted a live session and it booted up to the welcome screen. The only thing I did was have it find my Bluetooth mouse and then did a shutdown using the top right icon. It shut down normally.
Next I booted up again and chose Boot from first hard drive. It started loading and then executed lots of commands and ended up as below:
Notice all the errors. I am obviously totally lost.
Help, please. -- fey42
