Boot Camp disappeared from boot menu after changing partition
Hello, all,
Let me start by saying I am not very well versed in OS X related things. I'm the one everyone comes to to bring their Windows back from the brink, I understand computers well, it's just that I'm unfamiliar with how OS X works so please be explicit with steps when answering.
Background
* A friend has Boot Camp on her laptop, and wants more storage space on the Windows side.
* I installed the latest updates: iTunes 12.5.4, OS X El Capitan Update 10.11.6, OS X El Capitan Recovery Update 1.0.
* I couldn't change partitions from Windows, so I went into OS X and used Disk Utility to shrink the OS X partition, assuming I'd go back to Windows and expand from there.
* This broke Bootcamp/MBR/GPT. Now Boot Camp/Windows won't show when holding Option/Alt.
* Specifically, I get the "No bootable device -- insert boot disk and press any key" message when I force it to boot to Windows with Disk Utility.
* I've advised her to get more external space or a new Windows device, but right now I need to get Windows to boot.
* No, making a backup and giving her that is not an option. She's far from tech-savvy, she will want to use Windows normally to get her files.
* I've seen it mentioned that El Capitan is problematic with Boot Camp but I haven't found any specific information about this.
Actions taken
1. Used Disk Utility to delete the new, blank partition and integrate it back into the OSX partition, like it was originally.
2. Disabled System Integrity Protection: csrutil disable and csrutil status to make sure.
3. Followed this guide except arranged the three disks in the order 4 2 3. Successful but still no Boot Camp when booting.
4. Installed rEFIt and rebooted twice, it did not appear in the menu.
Below is the laptop's information. Please advise and thanks in advanced. 😕
