Bootcamp not bootable after partitioning

You can't edit partitions safely once Bootcamp has installed Windows.

Please give the outputs of the following terminal commands

sudo gpt -r -vv show disk0

sudo fdisk /dev/disk0

Was Windows installed in EFI mode?

Can you see the Bootcamp partition in OSX's Finder window?

In OSX go to the Bootcamp entry in the Finder window and open it.

In the Windows folder is there a folder called "Panther"?

Not yet.

In that Panther folder is a file near the end called "setupact.log"

Open that file please and in the console window that opens up there is a search box in the top right corner.

In that box please enter "Detected boot environment" and then the entry corresponding with that will appear below.

Does it say that the detected boot environment is EFI or BIOS?

Ok, thanks. You don't have an EFI install so your fdisk output is wrong.

As we can see form your gpt show output you now have 6 partitions on the drive. Ideally there should only be 4.

EFI

OSX (original)

OSX recovery HD (original)

OSX (new one)

OSX recovery HD (new one)

Bootcamp

With a BIOS installation of Windows the Windows installation boots using the MBR (hybrid) on the drive. That hybrid MBR has now been changed to a protective MBR, so Windows can't boot.

I'm not sure what caused this shift, exactly, but it's happened.

It may be possible to use gdisk to re-create a hybrid MBR. Windows may then boot, though there are no guarantees.

If you want to try that you should download and install gdisk from here

http://sourceforge.net/projects/gptfdisk/

I can then walk you through the process to create a new hybrid MBR.

Just to confirm, you haven't ever changed the size of the Bootcamp partition, have you?

Ok, so download and install gdisk.

The MBR can only hold 4 partitions (not 6) so we have to reduce the number to include in the new hybrid MBR.

Open up a terminal in OSX and assuming you have only one hard drive installed run

sudo gdisk /dev/disk0

type "r" (no quotes) and press enter

type "h" and press enter

You'll get a warning that hybrid MBR's are flaky and dangerous. That's ok.

It will ask for 1 to 3 partition numbers (space separated) so I would suggest you enter

2 4 6 (one space between each) and press enter - that means you're leaving out the recovery HD's

It will ask if you want to include the EFI partition first in MBR

answer Y and press enter

you will get default entries for partition 2 - accept them by pressing enter BUT

the last question will ask if you want to make the partition bootable - answer N and press enter.

Do the same for partition 4

For partition 6 accept defaults (checking that type 07 is the default option for partition type) but when it asks you if you want to make partition 6 bootable - answer Y and press enter.

When finished type "w" and press enter - to write changes to the partition table.

Answer Y to continue.

When done type "q" to quit gdisk

Close terminal

Reboot holding Alt key and see if Windows appears in the boot menu - try to boot it.

It's good to hear that this is now fixed 😁

However, you now have a decision to make!

You are running a system which will be unlikely to remain stable.

This problem is likely to happen again. If you upgrade any of your OSX installations the installer will probably do the same thing. Even using disk utility to check/repair the disk may have the same outcome.

The only proper way to stop this happening is to reduce the number of partitions to 4 (ie EFI, OSX, recovery HD and Bootcamp)., though that in istelf can cause problems if not done carefully.

Others would advocate that you backup everything you need and wipe the hard drive and start again with just one OSX system and a Bootcamp installation.

The decision is yours :-)
