how did you image the dd image to the vmdk the first time?
Although this now is solved somehow…
Maybe your imager messed it up or you might have to change the disk controller type that vmware emulates. It’s not all and everything about disk geometry.
Last time I rescued, converted and started a image it was not that much of a problem.
Why do you run qnx inside of vmware? It’s not going to be realtime that way, is it? If vmware won’t do - there are plenty equivalent virtualisation solutions out there. one might just boot it with no extra efforts.
