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. 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. 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. 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. When I select 'OSX' from the control panel Bootcamp utility, and reboot, the system goes into Windows regardless.
When I hold the ALT button at boot, the menu shows only Windows and there is no option to boot OSX.
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.
