Thanks Didier, Greg & Deloptes Right! So, TWO problems - I might have guessed I was getting poked from two sides at once... 1) PureOS doesn't do UEFI - yup, that would have lost me completely - thank you very much Didier for noticing that! 2) '... although if you have something like "Fast Boot" etc. could cause problems.' Hmm - I wonder - I do have 'Fast Boot' enabled... Thank you Deloptes, I will investigate. M
