You need to press the Option key while you start your iMac in order to get it to give you the choice of booting from a disk.

SOURCE: Disk won't eject on my iMac

Ok, I assume you have hit the eject button on the keyboard. Try dragging the CD icon on the desktop to the trash can. If that doesn't work, Shut down the computer and start up while holding down the mouse button. This may take some time, but keep your finger on the mouse button right up until the disc comes out or the log-in screen has appeared. Some Macintoshes have a paperclip hole that you can insert a straightened paperclip into, manually triggering the eject mechanism. Another option is to open Disk Utility and choose the disc you wish to eject in the left-hand pane, then click on the Eject button. Sometimes you can successfully use the eject disc button in iTunes even if the disc is not visible to the Finder. Another option is to Open Terminal and type "drutil tray eject" to eject the disc/tray, and "drutil tray close" to close the tray. Lastly if your computer has an eject button on the keyboard, restart the computer holding down the Option key. When the startup disk selection screen appears, let go of the option key and press the keyboard's eject button. One of these should work.

IMac will not start up.Question mark in a box comes up.Also will not boot up from start up disc

The operating system on the hard drive is corrupted, or the hard drive is not available. The procedure for starting from the startup disk varies a bit depending on the model of iMac. On the oldest ones (CRT iMac) and some of the early display-on-a-dome models, hold down the "C" key while starting the computer. This will force the computer to bypass the hard drive and boot directly from the startup optical disk. (If the C key doesn't work, restart and follow the option key procedure in the next paragraph.)

On newer Macs, hold down the option key while pressing the power button until you see that the boot loader is running. You should see an icon for at least one drive on the screen, perhaps followed by another. One of these is for the optical drive. It may take several tens of seconds for the optical drive icon to appear, particularly on older iMacs. Use the arrow or tab keys to select that one, then press return to start loading the system on that disk. If you only see the optical drive icon, that confirms there is a problem with the hard drive. Try Disk Utility anyway; if it can find the hard drive, there is some possibility of recovering it, or reformatting and loading from your backup. If the hard drive icon appears in the startup option screen, Disk Utility may be able to repair the problem if it is a file system issue affecting system loading. If a fundamental system file is corrupted, you will likely have to reinstall the OS.

In the worst case, the hard drive has a physical problem. Most of the time this is mechanical (sometimes announced with repeated, regular clicking noises as the drive vainly hunts for its starting position). Rattling noises (like the head has separated from its arm and is bouncing around) are also most unwelcome. Occasionally, the problem is with the controller board on the hard drive. In this case, if you can find another drive of the same model, you can swap controller boards (doing so successfully requires observing electrostatic discharge safety procedures to prevent zapping the drive, and properly identifying and operating the latch mechanism for the ribbon cable connector that connects the board to the drive mechanism). Generally, however, you have to replace the hard drive. Once in a while, the problem is with the cable between the hard drive and the logic board. On the old Macs with IDE drives (40-line ribbon cable connecting both optical drive and hard drive on some, two such cables on other models), there may be a bad connection on one wire because the wire is not properly seated in its two-tined fork inside the connector. To reseat the wires, gently push the cable down right at the connector shell (towards the surface of the connector shell that is pushed onto the pins of the drive or logic board). Do not put a crease bend on the cable there; you're just trying to make sure the wire is in the bottom of its fork. Repeat on the other side of the connector with the end of the cable (use a fingernail to catch the edge of the cable end).

Hold down c key wont boot from disk

If your OS disk is a DVD, and you have a CD-ROM installed, it's unreadable by the internal drive. You'll need to get an external Firewire DVD drive. Connect it, make sure it has power, then hold down the option key when you turn on the iMac. You may have to wait a bit for the DVD to read out, but you should see the DVD icon show up on the display. Select it (you may need to use the arrow keys), then press return to boot from that drive.
A flashing question mark with no readable optical disk installed says either the operating system on the hard drive is corrupted or the hard drive is bad.

My imac dvd drive reads DVDs but ejects CDs and installation disc

The optical drive has separate hardware for reading CD-disks and for reading DVD-disks.
So, "half" of the drive has failed. Replace the drive, since that will be less-expensive than an attempt at a repair.

I want to eject cd from cd rom apple system imac

To eject a CD/DVD that is not recognized by your computer, boot up while holding down the eject button on your keyboard, and continue to hold down eject until the disk ejects.

If this does not work, hold down your mouse button while booting up in the same way.

If neither of these work, open Terminal and type in the following:

drutil tray eject

If your disc does still not eject, your optical drive likely needs repair.

I install and bootcamp and resize the disk to 160gb. then i accidentally put the cd in the USB external cd drive. i forgot to put it in the Imac g5 cdrom drive. when i boot up.. its a mess my mac os x not...

I understand your problem to be that at the time you were executing the critical reboot just prior to installing Windows with Boot Camp, you placed the Windows CD into the wrong optical drive. Now your machine is stuck at the gray screen and is not responding to anything and will not boot from the system DVD
I have encountered this problem previously. The solution is to boot from an external drive containing a valid copy of the Mac OS. Although your machine will not boot from a DVD at this point, it WILL boot from an external drive if you hold down the Option key after you hear the startup chime, and select that drive's icon when it appears. Once you have successfully booted, go to System Preferences / Startup Disk to select the Mac partition of your internal drive, and your machine will reboot normally.

This leaves only the question of how you obtain an external drive containing a valid of the Mac OS. Some options are 1) a cloned backup drive, 2) another Macintosh via "Target Disk Mode," or 3) have someone create you such a disk from another machine. On the plus side, this solution involves no loss of your data, which makes it worth pursuing.
