    I had the same problem some others had with the slow startup of the new iMac. It would give me 40 sec to a min of white screen before seeing an Apple logo. It wouldn't even boot on my initial startup, I had to force shut it down and retry. So I did a erased the harddrive and did a clean install - problem fixed! Full bootup now takes 25 sec or so.

    If your iMac is taking longer than 5-6 seconds to show the Apple logo on the white screen on startup, you might want to consider doing this before you get too far into moving your files over! I wonder if they put a bad batch of software on in the factory - fortunately all is right with the recovery discs.

    Anyone tried to set up a new startup disk after first bootup?
    To some in a german mac forum it did help with the long boot-up time.

    If I do a clean install, will I lose iLife or is the suite included on the install disk that comes with my iMac?

    You should have gotten two gray disc, one that says OS X and another labeled Applications.

    Has anyone done a verbose boot to figure out what is actually going on when it's slow?? Reinstalling, while effective, seems like the sledgehammer approach. :D

    I always do a fresh install on any new computer. I have had too many machines (mostly from Dell) that have had botched factory installs.

    If it's booting slowly, try this first:

    Go to System Preferences > Startup Disk and select your internal HD.

    I had the same issue and was gonna do a clean install of Snow Leopard. I inserted the SL disk to boot from it, but it did not work. In the end I had to force the disk out of the computer by connecting a USB mouse and left click at startup. After that for some reason my iMac boots in 25 sec without reinstalling. Weird :/

    I'd have to think that Apple will release a fix for this in a pending update. I have definitely noticed that my 21.5" doesn't boot up fast enough, but I do not plan on reinstalling the OS - too much of a PIA to get everything back on.

    Quicker and better running OS >>> than any inconvenience of reinstalling OS and applications.

    Mine seems to take a while to show the Apple screen - maybe 25-30 seconds. But then Snow Leopard is up about 5-10 seconds later. Overall it seems like a normal boot time.

    Happy to report that my initial start up (first time when boot up) was around 50-60 seconds.

    After I went through the start up process, now it starts at around 30 seconds or less.. changing the START UP->HARD DISK makes minor difference in the start up.

    I am happy..... 30 seconds is good for me :)

    This worked for mine (21.5'', ATI Radeon 4670) as well. Thanks!
    Before, out of the box, the starting time was about 1 minute. Now cut into half, 25-30 seconds.

    Thanks. My new iMac was taking about 30 seconds to boot. After doing this it boots in under 14 seconds. Pretty cool.

    Thanks

    If you don't select a startup disk, the x bootloader doesn't immediately start, enters a default mode when it cannot find the selected boot volume.

    Basically, has to hunt for a drive with the startup volume on it, then load the x bootloader.

    While it should only take an extra 10-15 secs, it might try a couple few times to give the selected drive a chance to mount.

    This works perfectly. I selected the internal HD and now my mac is booting in aprox 20 seconds.. before it was taking 55 seconds.

    It worked!

    When I first got my new 21.5 imac it booted up in 58 secs. Then after installing 10.6.2 it took around 2 mins 40 secs.

    After altering system preferences (as above) it's just 25 secs!
