    Yesterday I tried to use bootcamp to install windows, however I couldn't get it to work. So I removed the partition and now when ever I reboot my mac I have to hold down the option key and pick my osx install.

    So how do I fix this and get it back to seeing only OSX?

    thanks.

    Open "System Preferences"
    Click "Startup Disk"
    Select Your OSX Installation (Ex. "Mac OS X, 10.5 on Macintosh HD")
    Either quit from Startup Disk or Press the Restart button.
    After that you should boot into OS X Automatically when you start up.

    Possibly a related topic... I'm having a problem with my portable external hard drive (a Western Digital Passport). I posted about this on various threads:

    One of the key symptoms is that Disk Utility says this drive is 2 TB (it's really 160 GB). Someone who responded to me on geekstogo said that the problem would have to do with my master boot record.

    Does anybody have any ideas on fixing the master boot record on an external? pref using a mac though I can use a PC as well.
