Dual booting with Clover?

[what]

Hi
I want to dual boot Windows 8.1 and Yosemite 10.10.3, on two seperate drives. What I have done so far:
Unplug my 120GB SSD and install Windows 8.1 on my 250GB SSD.
Unplug my 250GB Windows SSD, plug in my 120GB SSD and install Yosemite 10.10.3 on the 120GB SSD.

Now when i plug in both SSD's and boot, I get to the boot screen like normal, but there are two other options "Boot Windows from Legacy 1" and "Boot Windows from Legacy 2", or something along those lines.
If i try using either of them I just get a black screen with a blinking underscore in the upper left corner. I can boot Yosemite with no problems.

Can someone tell me how I can make it able to boot into windows also?

NOTE: I installed Yosemite using Clover.

Determine if you installed Win8 in Legacy or UEFI mode.
Disconnect the OS X drive
boot Win8
open the disk management tool as if you were going to format a partition
how many partitions do you see and how are they labeled?
If you have a MS Recovery Tools and an EFI partition in front of the healthy NTFS partition, then it is installed UEFI
If you have only System Reserved and Healthy NTFS, then you installed Legacy.

Cheers, it seems like i installed Legacy then. Do i need to reinstall windows UEFI then?

EDIT: I installed it using UEFI, and now everything works. Thank you very much
