    Okay, regular members here may feel exhausted or bored with that title. But yeah .. windows happens :D

    Now I have installed Windows 7 Ultimate bootcamp. Everything is fine, I installed and run a couple of games just fine on my iMac.

    But yesterday that shoddy windows decide to auto update, as you know it would install update, ask for restart and all.

    I shut it down and the next day I turned on the iMac, boot directly into OSX (it was set as default startup disk)

    After some time, I want to boot to windows for gaming by restart and press option, I have this following problem.

    • Pressing "option" button while cold startup freeze my Mac. Just a white screen and black pointer ala Bootcamp. But no HDD icons appeared
    • If I dont press "option" button during cold boot, everything is fine. I can get into both OSX/WIndows, whichever has been chosen as startup disk
    • I can still set startup disk from both OS. Whenever I switch and asked to restart, everything is fine

    In short, I lost the ability to switch boot drive -on the fly- by press option button on cold startup. It hang up my Mac on white screen and black pointer.

    I've reset my PRAM and nothing changed back to normal. Is this caused due to unfinished windows update?

    Any clue how to put this back to normal, without reinstalling windows from scratch of course. That was a tiring process.

    You know .. The problem is not too serious because I still can access both OS normally. But the ability of changing boot drive -on the fly- is much better, rather than boot into OSX first then restart into Windows, or vise versa.

    Please help

    A more descriptive title sure would have been nice.

    I don't know how to fix it, but you could install BootPicker or rEFIt to give you more boot options.

    Scrub it .. I resolved the problem simply by unplug my iMac for several minutes, and plug it back.

    Dang .. I should've done that on the first place. Luckily though I just end up reset my PRAM which does nothing big. If I wsan't patient enough, I'd end up installing the whole Windows from scratch. I hate to do that haha

    Next time, I'd try the simplest solution first. But still, I didn't find this in manual hahaha

    Thanks all
