I know this question has been asked a lot, but my situation seems to be a little different than most of the others I have been reading about. I haven't been able to find a solution that could fix this issue.

Basically, I created another ExFAT partition for universal storage between both OS's, and now Bootcamp won't load. I was aware of the issues with the Hybrid MBR changing after repartitioning, but I figured I could fix it after I resized.

I tried the guides here and here, which are so far the two main methods I could find online, with most of the others being a variation of the two. Both haven't worked for me.

Here is some info that might help to diagnose the issue:

I'm running Mac OS 10.11.6 and Windows 10. I can see the Bootcamp partition in Finder, and it does show up under startup drives in Settings. A lot of people who have this problem don't seem to be able to see either, so that is different. Also, I have rEFInd installed, so I don't know if that makes a difference either. SIP is also disabled.

Here is some terminal output:

Note that it may look a bit different than others' situations because I have already tried various solutions, such as the above code block. When I try to boot Windows, it comes up with:

Recovery
Your PC/Device needs to be repaired
An unexpected error has occurred.
Error code: 0xc000000e
You'll need to use recovery tools. If you don't have any installation >media (like a disc or USB device), contact your PC administrator or >PC/Device manufacturer.

I was wondering whether I need to either repair the partition or set a boot partition within Windows using a bootable USB/DVD.

How can I make Bootcamp boot again?

  • I posted the same question on the Apple community, and a genius over there was able to solve the problem. You can find it here. – Charlie Tobler Oct 7 '16 at 2:34
