Jan 5, 2015 11:23 AM in response to Loner Tby tdho,Hi Loner T. I'm new to this topic, but I've read lots of problems regarding hybrid MBR bootcamp.
I heard that EFI bootcamp won't cause that much problem, and apple began to support EFI on their products since 2013 generation.
I got macbook pro 15" mid 2012 (MD103), I did a little research on google, and I found this -> EFI and SMC firmware updates for Intel-based Macs - Apple Support
If I update the firmware, does it make my MBP got EFI bootcamp?
I've read your instruction to upgrade OS X on hybrid MBR using winclone, but I thought it would be nice if I could get my MBP to work on EFI.
I post my question here, so I hope that you would help me. Since you are good at this topic.
I might create a new thread after this. Sorry for my english.

From How to identify MacBook Pro models - Apple Support your MBP is MacBookPro9,1, which is considered a preUEFI model in the BC Info.plist. I am not aware of Apple retrofitting Macs for UEFI support.

<string>MacBookAir5</string>
<string>MacBookPro10</string>
<string>MacPro5</string>

<string>iMac13</string>
</array>
Despite this, I have tried EFI on a 13" 2012 MBP with Windows 8.1 and have had limited success in a full EFI boot.
I've read your instruction to upgrade OS X on hybrid MBR using winclone, but I thought it would be nice if I could get my MBP to work on EFI.
You should still try an EFI boot and see if newer drivers may be able to help, if possible and the Mac you have may be unavailable for a day or two. Please ensure you have backups of OSX and Windows, before you make any changes.

Mar 17, 2015 1:07 PM in response to mrgazzby GangsterChicken,Would it make sense to backup all the data in your Windows OS, "undo" the partition and go back to how you had your computer before installing Windows using Bootcamp. Then install the update to Yosemite, and redo the whole process of installing Windows using Bootcamp in the new Yosemite OS?
I haven't tried it, does this sound reasonable?

Jul 28, 2015 4:23 AM in response to Loner Tby A-L-P-H-A,I didn't know that the devs could be such morons!
I suppose I should make a fresh install of windows after the upgrade
tnx Loner

Jul 28, 2015 4:25 AM in response to A-L-P-H-Aby Loner T,Can you post a new discussion and include the output of the following Terminal commands? It may be possible to salvage the current installation.
diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.
