The compressed system is called livecd.sqfs in the root - /boot and 
/boot/grub are empty.

Thanks for all the pointers - I may try a different live CD .iso.

I will persevere as time allows. :-)

Off topic:-
Spent tonight trying to get grub2 to work with my on-board SATA 
controllers - still no go. It only sees the first primary partition sda1 
and the first partition in extended sda5. I can boot the PCLOS liveCD 
image in sda1 using the non-iso method and can use all partitions on all 
drives without issues from within that system (uses sata_nv). I can also 
boot into an old Mandriva installation on sda5, but none of my other 
installations.
It's really odd. So next I will check for a BIOS upgrade.

Cheers - Barry
