On a USB drive installation ............... I noticed that there is no Intel Microcode security update included.
So when I run the Spectre Meltdown Checker script it flagged up issues.

As there is an entry included in the
grub.cfg
I added the missing file from this thread

Saved, rebooted and run the script again with all issues resolved.
