Yosemite Windows UEFI on the same drive..

[EricJacobson]

Hello, I have installed Windows UEFI, and would like to install Yosemite on the same drive.

What i have done so far:

* Shrunk the disk to add extra partition for OSX
* Partitioned it as exFAT (Tried NTFS aswell)
* Booted onto OS X installation opened disk utility, tried to erase the new partition.

However it sais "Mediakit reports not enough space on device for requested operation" eventhough i have 55 GB free..

What to do? I heard that you could use GParted to change the format to HFS+ but is there a simpler way?

Im going crazy here!..

OS X is not well behaved with disks partitioned by other than OS X Disk Utility, but there are things you can check/do.

Make sure you select the correct icon for booting Windows.

And explain exactly what you mean by "clover is unable to boot windows"

This is what i looks like from clover bootloader.. unable to go throught to windows.. I have no more then one windows icon!

Post config.plist.

Here is the config.plist im currently using!

Set config.plist/GUI/Scan/Legacy=false. Because you don't expect to be booting Windows in legacy mode.

Also, there is an issue with your theme. The config.plist selects 'Bluemac' (GUI/Theme=Bluemac), but your photo clearly shows no 'Bluemac' theme installed.

Also, your ig-platform-id is wrong (0x0260006) which is not a valid ig-platform-id.

I know about the Bluemac theme. It wasnt listed in clover? I was unable to choose that theme. I have tried many ig-platform-id values e.g "0xa260005" "0xa260000" "0xa260006" " 0xa160000" however none of them works for some reason?
