I tried several weeks to get my P8Z77 WS to boot per UEFI from a QLE2560 FC controller and an X540-T2 per iSCSI (both work with BIOS boot). It just does not work. It seems to be an incompatibility between the board's implementation and the UEFI option ROMs on the controllers.
In the mean time I installed Windows 8 in UEFI mode to an SSD with a lot of software and would like to convert the installation to BIOS mode and transfer it to my fileserver for remote boot. One can find guide for the usual conversion from BIOS to UEFI, but not vice versa. My approach would be to make a fresh Windows install in BIOS mode and just overwrite the system partion with matching partition size. Since all boot information ist contained on the boot partition or EFI partition as far as I know, I assume this would work. I'm curious if someone tried that and was succesful.
