Repairing Boot Camp after creating new partition

Hello everyone.

I have a rMBP15 inch (early 2013). It has Mavericks and Bootcamp (Windows 8.1). I made a new partition for Yosemite public beta. After working a few hours with Yosemite i removed the Yosemite partition again. Now i have my Macintosh HD (Mavericks) and Bootcamp partition on my mac (like before installing Yosemite).

The problem is : Bootcamp doesn't show up anymore when pressing the option key at startup. It does show up in System preferences and when i set bootcamp to default startup it states after rebooting : No bootable device --- insert boot disk and press any key.

This is very familiar to this topic: Repairing Boot Camp after creating new partition

Could someone help me repair the bootcamp partition and make it bootable again (all my files are still there)

Here's a picture of disk utility in OS X: Thanks in advance!

MacBook Pro (Retina, 15-inch, Early 2013), OS X Mavericks (10.9.1), GHOSTING (and long shutdown issues)

Hi.

I just had this same problem and resolved it 10 min ago. The only difference in my situation was that I didn't actually install Yosemite, as I noticed the problem before I even had the chance to do that.

Just have a quick look here and follow what it says: Repairing Boot Camp after creating new partition

If you get stuck or run into any problems, feel free to ask.

Thanks for your reply!

I'm looking into it right now.

Do you think the values he gave you like ''7'' apply to me as well?

Yes. The values are not related to disk size, but only to the Bootcamp partition configuration.

07 is partition type for Windows (MS Basic Data). Flag marks the partition as bootable and active.

You can also check the man page of fdisk in OSX Terminal with man fdisk command. See the qualifier '-e' and the various commands.

Everything worked and is ok now.

Thanks for helping me and other people out!

I've tried out many beta versions of OS X but never on a mac with bootcamp.

It's a shame disk utility doesn't provide a build in option to fix this issue considering

the fact many mac users install Windows.

Till Macs start to support UEFI/EFI 2.0+ instead of staying on EFI 1.1, this problem will continue. You can install 10 different partitions on a single disk of various OSX versions (that the hardware supports) because all of them use GPT disks, but Bootcamp is the odd one out because it still uses MBR and CSM-BIOS.

I understand your situation. I had the same problem and thanks to Loner T it's ok now. I replied at your discussion with the solution that helped me out. But i think you now have removed your discussion. You don't have to reinstall everything from scratch.

No i can`t they send me this "We removed your post Reparing Boot camp after install beta yosemite in a partition because it contained information about beta software available only to Registered Apple Developers."

so i ask a new question Repairing Boot Camp after creating a partition.

Thank you for answering 🙂

I have just responded to your post. Do not reference any Yosemite-related information, but the Bootcamp issue can be corrected.
