I still have the fast or slow option in build 10162.
Yes, I couldn't get through that, so I did a clean install from the ISO file. I saw some ridiculous 'recipe' for fixing it on Neowin or some such with what seemed liked dozens of fiddly steps that seemed more like superstitious incantations than really showing any understanding of the underlying problem. Much faster to simply clean install :)
I just read a similar thread to the Neowin one on the Microsoft Community forum.
Thing is though for build 10162 I downloaded the ISO formatted my existing Win 10 partition and did a clean install.
So unless I re-format and try yet another clean install I guess I'll just have to live with it until we get a newer build or RTM comes out.
