Password protection is not letting to boot from WD... Help!

I have got 1TB WD Passport. I have made two partitions, 1st one is formatted in Mac encrypted format to backup my macbook pro (bootable) and 2nd one in ExFAT format (for Windows).

Since I have password protected the drive using WD security software therefore it doesn’t allow me to boot up from bootable partition. However it allows me to boot from it if i remove the password. Is it somehow possible to address this issue. Even password protecting only one partition would help but the software doesn’t allow me to do that.

I really appreciate your help in this regards.


That’s not an issue. That’s how the drive is supposed to function.  If you want to use the drive as a bootable drive, then you can’t password protect it.
