    I recently had a blue screen and evidently a corrupted windows 10 partition on my '13 RMBP. Instead of reinstalling win 10 I wiped the drive and installed win 8.1. Everything was going smoothly until I updated all drivers to the latest. I now get a restart loop just after logging in. I think I have narrowed it down to an external thunderbolt hard drive. I get the loop when it boots with it plugged in and no loop when it is unplugged. Anyone experience this?

    No one else has any experience with this? Or knows what could be causing this?

    I have had issues with external Thunderbolt SoftRAID drives which I traced back to the Apple HFS drivers included in the BootCamp driver package. Disabling the driver fixed my crash (" CACHE_MANAGER ") .... but Windows can no longer access my OS X disks (a BONUS I think). This worked for me ... hope it works for you.

    The driver in question is called AppleHFS.sys. You can find it on your system drive under Windows\system32\drivers\AppleHFS.sys

    Boot without your external drive attached, then navigate to that folder and just rename the file to e.g. “AppleHFS.sys AppleHFS.sysBAK” using the file manager.

    Thanks! Yeah this worked. Bummer I cant access the OSX drive but I think I can manage. Just as long as I don't need to unplug my external RAID drives every time. Cheers.
