A bit more information might help.
If "your situation" doesn't include Windows Vista -> Windows10 then EasyBCD certainly wouldn't be appropriate.
Else EasyBCD Basics
will probably tell you what you're doing wrong.
I have Ubuntu 16.04 on a partition of my E: drive. It doesn’t show up in the iReboot menu, and when I select it in EasyBCD, where it does show up, it still boots to Windows after restart. I have to use F2 and bios to make the switch between.
You can see then that the problem is a MS prohibition in the bootmgr.efi version.
There's nothing that EasyBCD (or anyone) can do to make it do what it's designed to prevent from happening.
The only recourse for a determined W10/Linux dual-booter on a UEFI PC, is to let grub take control of the boot. It has no qualms about booting other peoples OSs
