Thanks.
Yes attempted this earlier in my troubleshooting and just tried again. The boot to HDD process cannot get past "decompressing kernel cache lvzn" it then loops with another boot attempt. The only successful way for me to boot is via booting from USB. At times there is a chimera\chameleon GUI image of both the HDD and USB drive with a RED drive light, wondering if the means anything at all to the supporting audience. I really would like to stay away from a new install.
Thanks,
Dali
