    yes I already did all these steps.
    meanwhile there is somethimes a big pixeled black/white/grey combination of pixels on the left, after the wheel stops spinning.
    Iam very confused :confused:
    This happend after I deleted the ACLs via command+S terminal.
    It shows:
    bootcachecontrol..... not found

    after a lot of research I have some questions about bootcachecontrol.
    Is the bootcache.playlist installed on the hard drive?
    Iam totally confused because with no harddrive connected It also stucks on the spinning while when I want to start via install-cd.
    The only thing which is working -> the Hardware-Test and it shows no faults.
    :confused:
