Thanks for getting back. I managed to change the boot disk back to the old one by holding down the option key and the start button when restarting the mac as described here Change your Mac startup disk - Apple Support

Big problem AGAIN! finally sorted, it was a space problem, hunted down by second senior support guy, EXCELLENT work.

Failed during auto update. Safe Mode fail. Clear RAM fail. Recovery Mode fail.

Recovery mode Space problem found.

There needs to be a warning about the space required, the "new" update method seems to require a lot of extra space.

Bought a 500GB Mac mini, it is not a viable machine you MUST have extra serious storage from day one. I have learned a lot more today from all the support people. Thanks.
