EasyBCD was made before Windows 10 was released. So it is not fully compatible. For information, you need to check with them.

Below is a relevant link about your problem.

EasyBCD v2.2, older one that worked on W7 doesn't work on 8/8.1 or W10 properly.
My situation yesterday:
Win8.1 on primary boot disk SSD
Win10TP on secondary HDD, both bootable by themselves.
Updated W10 and boot was screwed up royally. 5 entries at boot and only W10 would boot.
EasyBcd was installed on primary disk too. I installed EasyBcd on W10 and set boot order and menu, it was down to two W8.1 and one W10 on the boot menu. I found executable EasyBcd file on SSD with W8.1 and run it while still in W10, set the boot order and everything came out right. Now I can BOOT thru BIOS to either of disks and get exactly same BOOT menu.

Myself, I no longer use EasyBCD.  Instead, I use the boot manager of Windows 10 and boot three versions of Windows.

I see the moderator has moved this to Windows 10.
Hes is right. This is a Windows 10 issue. Use the boot manager of Windows 10.
If you have a the  install DVD of Windows 10,l  you should be able to fix the problem and not need to o use EaasyBCD.

I could be wrong but i believe EasyBCD has to be in place prior to the 2nd OS being installed...not after the fact.

They said

"You can't boot a newer Windows version using an older Windows bootmgr.
e.g. Vista can't boot 7,8,8.1 or 10,
7 can't boot 8, 8.1 or 10
etc.
This is because the older bootmgr sees the newer version of winload doesn't have a signature that it recognizes as genuine.
bootmgr can only be backward compatible i.e recognize contemporary or older signatures on winload.
If you want to dual boot two versions of Windows, you must either boot the drive with the newest version of Windows and add entries for older systems to its BCD, or you can copy the bootmgr from W10 in place of the one on whichever older version of Windows you are currently trying to boot from."

I removed both entries and tried too boot off the Windows 10 drive.  I removed both entries now from Windows 7 and tried too bring up the Windows 10 drive and now getting

\boot\BCD

0xc0000098

The windows Boot config file
