Win 10 & Ubuntu 15.04

I have Win 10 and Ubuntu15.04. Really would like to be presented with a choice that works. Tried disabling Fastboot, No Change, Depending on when and which direction I'm going, I get a nice blue GUI or a DOS-like monochrome screen offering the choice between OS. Neither works. I can only reach Ubuntu from Windows by forceing into UEFI settings. Which is OK, cause I don't use Ubuntu much, but it's not clean, and it's inconvenient. This was the whole purpose for EasyBCD
