How to fix Boot Camp partition that won't boot

Soooo...coming new to this thread, after reading of it on NERDR.COM.


Have new iMac 27" and have been TRYING to load and use Win 8.1 Enterprise (MSDN) on BootCamp in Mavericks 10.9.3.


Could not even get setup to load until after I removed my three external G-Drives, finally got it to load, and actually got Windows pretty much configured and activated, and loaded Office 2013 and VISIO. But, I have an increasing number of BSOD (I assume it is) issues with kernel_security_check_failure which stop the computer, nothing works, and I have to power off. This has caused drive issues, and while I've been repairing them, I can no longer boot into Windows. Tried repairing that with the original Win 8.1 DVD, but, Automatic Repair can't fix, and I was unsure if using BootRec was a good idea?


So ran the three SUDO commands on my Drive 0, and here are the results (had to paste a screen shot, as, SOMETHING in the middle (blue) text won't allow me to post it):

Question is, should I go ahead and use the gdisk utility to repair things, or...something else?


And...if there is some kind of issue with using Boot Camp when you have external drives attached, what can be done to get around that?


Thanks!

iMac (27-inch, Late 2013), OS X Mavericks (10.9.3)

The fdisk output shows that it is a single GPT disk. Has any disk manipulation been done, like resizing or repartitioning.


Your GPT looks correct. If you create a Hybrid MBR via gdisk and include partitions 2,3 and 4 and make 4 bootable, does Windows partition show up in Startup and as a separate volume in Finder?


Please see https://discussions.apple.com/thread/5641066 for Hybrid MBR creation.
