I also can’t add space to the System Reserved partition and then add that space to the EFI so my only option is to delete. The reason I’m going to delete the System Reserved partition is because the EFI partition needs to be next to a partition like the C: partition which we can take space away from and I can’t do that the with System Reserved partition wedged between. So my only option is to delete the System Reserved partition as it’s not as important to have as the Recovery partition. I’m not able to get enough free space from the Recovery partition or the small 16MB system reserved partition to reach 200MB. Everyone’s partition layout will look a little different.Īs you can see in the image above to the left of my EFI partition I have the Windows Recovery partition and to my right I have the System Reserved partition / (Other) 16 MB. To increase the size of the EFI partition we need to take away space from the partition before or the partition after it. So we need to increase the size of the partition to 200MB.

When a hard drive is formatted in Windows or macOS it creates a hidden partition called “EFI” macOS requires an EFI partition of 200MB in size to install macOS, but if you’re drive was formatted using Windows that EFI partition is only 100MB in size.

So I went for BootCamp, which I had successfully avoided while I was using the HD 2600. I wasn't able to sort the dual boot issue with EasyBCD, as it wouldn't recognize the OSX partition (tried many different settings, removed the other HDDs, renamed the OSX partition, still a no go). I have a Sapphire 6870 working well on my MacPro 3,1 (10.6.7 and Win7 installed on the same HDD).
