Hi Colin,
Agreed but what still puzzles me is how I was able to clean install and update all the way from 14393, through 15063, to 16199 on 64bit builds without a problem yet none of the ISOs I have of subsequent builds, including 15063 and 16199, will allow me to
clean install on a bare drive.
As I've said elsewhere, the ISO of 15063.0 kicks off OK but halts in the old school way requesting drivers (the old Windows 7 64bit ones are not surprisingly rejected) which are either missing or corrupt, before I get to the stage of selecting a partition
on which to install the OS.
My thought was that the drivers went missing or were corrupted some time after build 14393 (although updates to 15063.483 went well) leading me to surmise that the UUP process, in some way up to but not after build 16199, migrated the already installed 64bit
drivers. Either that or something in the later builds rendered the drivers useless whether they were included or not.
Whatever caused the problem means there's no way to clean install from build 15063 or later - unless reverting to 32bit works which I have yet to test. If that does work then I guess it's better than nothing but it does mean a clean install, downgrade 3rd
party apps and, without doubt, will cause havoc for a number (how many I can't guess) of happy users with 64bit installations when the Fall update is let loose.
Communicating all this via the Feedback Hub is next to impossible given the limited space available. I can only hope that someone from Microsoft involved with Windows 10 development is reading the posts on this forum AND actually informs someone who can
do something to correct the problem.
Cheers.
