It seems odd that you would disable UEFI functionality by using legacy boot.

Most distributions support UEFI now, and it gives you capabilities for
managing dual boot which are more troublesome in BIOS mode.

My experience is you need the following:
1. Disable secure boot

2. Make sure that you boot from your media in UEFI mode.
Most often there are two entries for your boot media in the boot menu, one
for legacy mode, one for UEFI mode. If you use legacy mode at this point,
you will never be able to boot your system using UEFI

3. You need two extra partitions to support UEFI
You need to be using GPT partitions, so the cost of two partitions is
negligible. One is for the GRUB boot code, and will be labelled in the
installer some think like 'BIOS boot area'. This only needs to be a few
megabytes. The second is a EFI boot area, which has to be vfat, and needs
to be a few tens of megabytes.

Once you have installed using UEFI, you can edit the boot order from linux
(or windows) using efibootmgr (or an equivalent in wundoze)
