Q: iMac won't restart after latest security update

I have a late 2007 20" iMac with OS 10.10.2. While we were away last week I asked my son-ln-law to send me a photo off my iMac. He started the iMac and sent the file no problem. While he was on there he asked if he should run the security update while he checked the house so I said sure why not. He ran the update and came back in a few minutes and mac was off. He tried to restart it but it won't continue. It starts, the chime sounds, the Apple logo appears, it goes about 1/3 the way through the progress bar then sits there about 2 minutes and then shuts down. Trying to help with good intentions he found my Snow Leopard disk and inserted it thinking he might be able to use Disk Utility to eject the disk but since the disk is mounted an error message says the disk cannot be ejected. Not knowing what to do he just held the power button and it turned off.

 

Now that I'm back home I can't eject the SL disc and not sure what to do next. I've tried everything Kappy suggested here but nothing works. Unknown to my son-in-law I do have a Yosemite USB bootable drive but how do I run it with the SL disc in the DVD drive? I'm assuming I can restore from a time machine back up but with the SL disk in there does that cause a problem? I can see the Yosemite USB disk along with the SL disk in Disk Utility but not sure what to do if anything at this point. Suggestions?

    The key just to the right of F12 has an arrow pointing up with a line under it, push it in and hold it if there is anything stuck it will eject it. If you are trying to upgrade to yosemite I suggest using the App's Store it is free.

    Thanks Don but as I said it has Yosemite 10.10.2. The disk in the drive cannot be ejected. The problem developed when the update tried to restart.

    Well I managed to get the Snow Leopard disk out and restarted the mac using OS X Recovery. I've selected the option to reinstall OS X. I'm at a screen that is asking me to 'Select the disk where you want to install OS X'. I'm presented two options one labeled 'EFI' and the other 'Recovery HD'. I chose the later but it's been sitting on a spinning beach ball for 30 minutes now so I can't select 'Install' to proceed. Any idea what has happened to my mac? A hard drive failure I assume or something else?
