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. You’re only option would be to reinstall Windows in UEFI mode or install macOS first.
