How to choose EFI boot partition during install?

Hiya,

I'm trying to set up a new system to dual boot Fedora 19 and Windows 7. I've run into a problem and am hoping someone can help!

I've first installed Windows 7, since it doesn't like to give me a choice about where it wants to be installed. This has created the following partitions:

/dev/sda1 Windows System (100 Mb)
/dev/sda2 Windows Reserved
/dev/sda3 Windows 7

The Windows EFI files are placed in /dev/sda1.

What I've tried to do in the Fedora 19 Full DVD installer is to create these partitions:

/dev/sda4 /boot/efi
/dev/sda5 /boot
/dev/sda6 (LVM with /, /home, swap)

I've set the type of sda4 to be EFI, and chosen the correct mount point.

Although the Fedora installer correctly detects that it needs to install an EFI bootloader (yay!), it places this in /dev/sda1 rather than the /dev/sda4 I suggested to it - which clobbers the Windows 7 bootloader.

Is it possible to control in which partition the installer places its EFI files? Any help appreciated!

Cheers! :)
