I installed Windows 8.1 Enterprise via Bootcamp on my MBP (Nov 2013 model), now I can only boot into Windows, no way to boot into OSX.
When I hold the ALT button at boot, the menu shows only Windows and there is no option to boot OSX.
When I select "OSX" from the control panel Bootcamp utility, and reboot, the system goes into Windows regardless. Windows works just fine (I'm using it now) but my main setup and a lot of work in progress is on OSX so I really need to recover it. Anyone knows how to recover the OSX partition, so that I can boot into OSX ? I'm happy to drop Windows if that's the case, but I cannot proceed with a fresh install wiping OSX.
The laptop is a MacBook Pro November 2013 model, with one original SSD drive (without DVD drive, however I have an external one) and I don't have a OSX installation disk, so I could not try recovery utilities etc.
I have tried a couple of Windows utilities, trying to change the Active partition, but for some reason that option is always grayed out, even DiskPart doesn't allow to set it.
I checked Disk Management and the OSX partition is still present (partition 1):
Disk 0: Partition 0: 200 MB - EFI System Partition Partition 1: 837.57 GB - Primary Partition Partition 2: 620 MB - Primary Partition (no idea what this is for) Partition 3: 93.47 GB - Boot, Page File, Crash Dump, Primary Partition
and this is the output of MS DiskPart utility:
DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 931 GB 0 B * DISKPART> select disk 0 Disk 0 is now the selected disk. DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 System 200 MB 20 KB Partition 2 Unknown 837 GB 200 MB Partition 3 Unknown 619 MB 837 GB Partition 4 Primary 93 GB 838 GB DISKPART> select partition 1 Partition 1 is now the selected partition. DISKPART> active The selected disk is not a fixed MBR disk. The ACTIVE command can only be used on fixed MBR disks.
This How do I make my Boot Camp partition bootable again? seems to be very close to my problem, but rEFIt is distributed in CDR format, I tried to convert that to ISO and burn to a USB with no luck, the system won't see the USB.
Anyone knows of other ways to fix Bootcamp loader to show OSX partition ?

I had the same error after installing windows in bootcamp. I rebooted and the OS X partition was not an option, only windows. I checked in disk management in Windows and the partition still existed. I tried booting in recovery mode (command+r), but received an error message. -4403F
Apple support had me boot in internet recovery mode (command+option+r), which did successfully load.
I then went to disk utility, and the Macintosh HD disk was grayed out. I clicked on the mount/unmount button and had to unlock my computer. It turns out I had used file vault, which encrypted my hard drive.
Somehow that kept OS X from appearing after I used bootcamp. After unlocking it, I was able to verify and repair the disk.
I booted to windows and the bootcamp utility appeared. I clicked "Restart in OS X." OS X booted without a problem after that.
