With UEFI, you do not need EasyBCD. That just adds another boot menu. You have UEFI's boot menu and grub's boot menu already.

Did you install Ubuntu in UEFI boot mode?
You can only dual boot from grub menu if Ubuntu is also installed in UEFI boot mode not BIOS/CSM boot mode. But you should be able to dual boot from UEFI boot menu, but may have to turn on/off UEFI or CSM/BIOS/Legacy mode to match install.

Also what brand/model computer?
Some require work arounds to boot ubuntu entry in UEFI mode. Some will not boot ubuntu entry and only a hard drive entry which we make really be grub or shim.
