BIOS Just show 1 HDD in the boot options

[motionfrog]

Hello.
I'm using MSI h110M pro-VH plus,
So the condition is I have 2 HDDs right now, installed windows 10 and Ubuntu in the second HDD.
lets call them as HDD A and B. I opened the boot options from the bios and it just showed up the HDD A. so I can not boot from the HDD B.

in the bios, there's a setting to set the HDD priority, so if I set HDD B as #1, when I entered the boot options, only HDD B showed up. When I changed the #1 priority to HDD A, only HDD A showed up in the boot options.
PS: the 2 OSes use the legacy option, not the UEFI.

Anyone can help me to get both HDDs showed up in the boot options? so I can easily boot up between both HDD. Thanks

in bios is it showing both drives. i think you have to partition 1 drive and install the o/s on the partition drive
