Windows 10 crashing, but not sure why.
In the last couple of days, Windows 10 fails to start when switching from OS X to Windows in Bootcamp. I recently installed the latest update to OS X El Capitan and Windows started fine from Bootcamp. After about 3-4 mins in Windows -- it was downloading and installing updates -- screen goes black, and then a screen pops up indicating "Attempting Automatic Repairs". Those automatic repairs failed. After several attempts to restart, I eventually got a "no bootable disk found" error.
So I decided to use Bootcamp Assistant to uninstall Windows and remove the partition, and then do a fresh partition and windows reinstall. Same thing happens. Windows installs fine, runs fine for 3-4 mins and then crashes.
I have no idea if this crash is due to a Microsoft issue involving updates, a conflict involving Bootcamp or Apple drivers, or something else. Anyone have ideas?
