Clover will not show Linux to boot from

[seskanda]

Hello

 

I have OS X 10.10.5 on an Inspiron 7347 and managed to install Clover on an SD card. But while OS X 10.10.5 and Windows boots from Clover, Linux (Slackware 14.2, to be exact) does not even show up in the Clover's menu. However Slackware does show in the UEFI F12 Boot screen and boots fine. Any clue how to fix this ? I attached the config.plist

 

Thanks in advance
