Do you have any idea ? While I tested the same ISO on different computers yesterday, I've seen this error on one of them. Judging from the error message and the fact that the same CD worked on other computers, I believe this is due to the combination of CD media and CD drive. I know from reading many tests of CD burning media and drives, that the combination plays a big role, and some drives are not good at reading certain media. Did you burn the disk on the same computer that you are trying to install Haiku on? Best regards, -Stephan
