Got myself a pi3 a few weeks ago. I’m new to this environment. Mounted recalbox on one sd card to relive the good old days. installed raspbian on another sd card for other purposes . Everything worked fine. Reading about the pi3 i figured i could have a dual boot SD card. I followed all the step very carefully.
Went through the whole process installing noobs copying the files to the OS folders etc. Now when i Turn on the pi noobs boots up , when i select raspbian it boots without any issues. When i select recalbox Nothing happens the green led on the board is not blinking.
Got on to read a bunch of forums, checked my power supply, reformat SD card, did new install, same problem. There is obviously something I am missing here but what?
