dual booting with Yosemite and win8.1 non-UEFI (help)

[allenwkk]

I use Chameleon to boot Yosemite and it works fine with my ASUS P6T SE (no EFI). I recently installed win8.1 on another HDD(using original DVD disk) . When boot, it always goes to win8.1... no matter how I set the BIOS boot priority. 

 

I have to make the win8.1 HDD inactive in BIOS to get back the Chameleon boot screen, then to Yosemite... If I use the Chameleon's window icon... it cannot boot to win8.1.

 

I tried installing BCD to win8.1 but as I boot to win8.1, the BCD selection screen never shows up.

 

any Help... thanks in advance.

 

edit: found using Chameleon to boot windows, one has to use the "windows system reserve" partition instead of the "windows" partition itself.
