Might be late to this party but when a clean W7 install fails on a new hardware system (when apparently all went fine and left doing windows updates) the problem is often that the W7 OS drivers cannot deal with much newer 4K-sector hard disk drives - The same problem frequently causes Non Genuine Windows Installation warnings too before the final mess-up.
The root cause is an out of date version of the Disk-storage drivers that Windows 7 installation disk has on board and the updated version - while available- is not prioritised enough to update before the warnings and crashes start . .
I have absolutely NO idea what any of that means,,,,, I did say SMALL words I think,,,, :C
anyway, Im off out to arenacross at the men, ,
its not looking good for getting this sorted tonight, I cant even find where the stupid thing downloaded W10 to, one would have thought the download folder, but, alas, its empty in there, :shakehead : headbang so I'm just going to try an upgrade on it,,,,,
