UEFI Windows partition, change to legacy mode?

[Going Bald]

That's exactly what I'd like to know. I guess I'll just try out and see if it works without having to reinstall OSX from scratch.

To change from Clover UEFI to Clover Legacy:
Boot to UEFI, enable Legacy BIOS boot, save&exit and continue boot to desktop
Mount the EFI partition on the boot drive
Delete the EFI folder in the EFI partition
Install Clover using the Legacy mode selections and check install in ESP box
edit config.plist to get the settings right for your hardware and save
Reboot
