Hi guys,

Thanks to the resources and everyone here at Tonymac i have got my first hackintosh up and running!

However, i have set my system up to dual boot Windows as well, on its own seperate SSD.

I followed Going Bald's excellent guide here

My problem came at disabling windows from booting UEFI.

As my GPU was UEFI supported i installed OSX via Clover (Using shiloh's excellent build guide here) with 'Launch CSM' disabled.

So the windows install CD wouldnt show up as SATA, only UEFI, so i decided to put 'Launch CSM' to enabled and allow Legacy only, not UEFI.

I installed Windows 7 like this and it booted up fine, i then plugged all my drives back in and rebooted, turning 'Launch CSM' off to boot OSX in the BIOS and OSX works fine.

Obviously upon boot i now only see the OSX drive and would have to change the BIOS everytime to boot on Windows.

The reason i didnt follow the Chimera multi boot screen step at the end, is because i used Clover, and wasnt sure how this influenced the process and how i would go about it.

Note: I didnt format my Windows drive before install, i left that part to the Installer itself.

I have done my best to research and find the answer to my question, but i am still new to a lot of this and it is proving hard to wrap my head round.

Any help is greatly appreciated!

Thanks in advance!

If you enabled CSM to install Win7 in Legacy mode then you need to leave it enabled if you do not want to change BIOS settings when booting Windows. Having CSM enabled will not make any difference to Clover or OS X

Hi Going bald, thankyou for your reply, and guide!

I was also confused as to how to create a multiboot screen with Clover, in your guide you specified using Chimera, would it change the process because im using clover instead?

No, Clover will give you icons for Windows same as Chimera does. You just have to find which one boots your Windows and hide the others.

An Update on this one, If I disable the CSM Support in my BIOS, I can boot to Clover, but I can only see that partition. I have 3 drives, 1 windows, 1 mac, and 1 to run hackintosh tests (if something goes wrong I don't touch my OSx drive).

So, should I have to enter BIOS every time I want to change platform? That din't happened in my old build.

Thanks in advance.
