dcv5 are now integrated with the time machine, so if you did not installed the timemachine ipl, dcv5 may o may not boot up depends on the config.txt, just install first the ipl loader for timemachine, then reinstall the dcv5 then it will ask what button you will be used, (mine i;ve used the left dpad button) then after you press it in a couple of seconds, it will install dc files, then when finished, check if it will load when you press left button, if not, check the config.txt in the TM folder and try to change the configuration
