    Hi guys.

    I originally uninstalled windows using bootcamp, and gave all the space back to Mac OS X. About 4 hours later I decided I wanted to reinstall it (no comments please). Then in the middle of the reinstall I decided that I actually don't want it, and went back into Mac OS X and restored it, deleting Windows with boot camp.

    Now, everytime I boot the screen stays white for a long period of time, then it goes black and in a console looking grey font it says "No readable device to boot from."

    Now when I hold alt at bootup and manually press Macintosh HD everything boots up fine.

    Thanks in advance.

    (If you think I need to do a reinstall thats fine, because I have everything backed up via Time Machine.)

    can't make up your mind can you?

    Just go into system preferences in OSX and click startup disk, then select the OSX folder.

    then go into disk utility, repair, and check to see if you've deleted your windows partition. Delete it if you haven't and resize your OSX partition to take up all the space you need.

    Thanks lol, selecting OSX as startup worked.

    Yeah I have trouble making my mind up on small decisions like which OS to run on my MBP. Then life changing decisions come easy to me >_>. Thanks!
