    Hi, I recently acquired a MacBook Pro A1260. I know this model is old, but I have no idea why it refuses to boot fully.

    When I try to boot into OS X, it freezes halfway through or restarts halfway through.
    When I try to boot into windows, nothing shows up but a black screen.

    Has anyone encountered a similar problem on your Mac?

    PS: I know that this model has a very common video issue, but the Apple logo screen does not have artefacts which makes me believe it was because of some other reason.

    Hold the command + v keys down when starting it to get text boot to see where it fails.

    Hi, attached is the image of the part where it freezes. I'm booting from an external USB installer.
    Hope you can help me

    To add on, normally the similar model MacBooks will shut down if press the power button while it is chiming. However, when I try to shut down when it's chiming, the chime simply cuts off and there is still a white screen.

    Graphics definitely load so not that I see couple of file not found errors in it. Where does the installer come from, how was it created, what OS are you installing, why no booting from internal? Those kind of details would be helpful you may want to try command + s to boot in safe mode to see if that will allow it to start.

    Command + s is single-user mode, not related to safe boot mode.
    boot into Safe Mode by restarting while holding the Shift key.

    A lock up, or restart in the middle of an attempted normal boot, is often a result of a hard drive that is failing, or already has failed.

    I'm booting through a USB installer I created on another Mac as I already wiped the original hard drive from elsewhere thinking it was a software problem.

    I held down shift during boot and got a kernel panic: do refer to attached picture

    I see something related to CPU. Could it be something is wrong with the processor?[​IMG]

    Apparently El Captain from the 15.0 for the kernel on a just barely making it MBP4,1 from the supported list. Seems like you are getting various different problems trying to boot this machine on that os perhaps you should try a different OS. A clearer picture to read in future would be helpful as well that one here is just barely passable for me to see it is cut off on the left side.
