Gpt error bootcamp

[CEOofApple]

Hi.
When installing Windows 8.1 PRO on my laptop, I seem to be getting a GPT error . I have done bootcamp before but i guessed that something happened in the process. I have tried to learn how to change MBR to GPT but everything seems confusing. I have tried many ways to bypass this error but nothing seems to work. Please help.

Thanks, CEOofApple

It would help everyone if you described EXACTLY what error message you got.

You don't need to "turn MBR to GPT". You may have to format your partition correctly as part of your Windows install (I did). You may have to use the correct installer.

Please try saying what you have done with as much detail as possible.

Disk Utility is weird when formatting as FAT32.

Even though it appears as GPT to OS X, Disk Utility formats it in a hybrid way, so that OS X sees it as GPT and Windows see it as MBR.

You'll have to use gdisk (free command line utility, obtainable from github) and use it to remove the hybrid MBR part to make it a pure GPT disk.

Are you sure? I did do that (as my Mac OS didn't support Windows 8) but surely with Bootcamp normally you should you just click next, next, next?

I didn't have to do that on any of my Haswell Macs, but I sure as hell had to do that on my sole Sandy Bridge MBP.

Haswell Macs have UEFI 2.0 and so BCA will install Windows in UEFI by default.

But not Ivy Bridge and earlier.
