Had same slow boot with Windows 10, fresh install following hard drive replacement. Was taking 1 minute 20 secs to load windows. On a Lenovo z50. Found the Bios time and date was incorrect. Set the time and date correctly and now takes 8 seconds. Vast improvement but no idea why this would cause it though I did notice Windows set its own clock. Must have been of the internet somehow.
