    So after a few weeks of messing around with it, I deleted the Yosemite beta partition and converted my MBA back to full Mavericks. However, since I did that, the boot process is horribly sluggish. What used to boot up in 6-10 seconds is now taking 20-30 seconds!

    When I first tried to delete the Yosemite partition, it was was greyed-out so I did this:

    (Many people did this, from all the comments.) Anyway, since then I fixed permissions (for what it's worth) and the darn thing is still booting slow.

    I suspect my '12 MBA's sloth-like behavior will cease upon clean-installing Yosemite release later this month. Still, I'm wondering if anyone else has had this issue? Did removing the Yosemite partition do something to Mavericks?

    Here is my current partition:

    Go into Sys Prefs > Startup Disk and select your Mavericks partition, then see whether that helps.

    I never thought of that since it's the only partition but by Jove it worked! :)

    Hehe, thanks :)

    Why it works: Basically the system still tries to boot from the last selected partition, which in this case no longer exists. It then goes through a lengthy detection routine to find all possible boot devices. By selecting the current partition it now skips the detection again.
