Why is my iMac not booting up?
Since I installed the last Yosemite update (Version 10.10.5), my iMac will not fully boot up!
When it starts, the boot screen (Apple logo) and a progress bar appears. The progress bar fills up until its about 2/3 full then nothing happens. I have let it sit for days to see if it will finish booting and nothing happens. I have also tried the boot-up shortcut keys and nothing happens.
Can anyone tell me why this is happening? Will I need to upgrade my CPU?

Will it boot from the original system installation optical disk?

I have not tried booting from the original system disk. I have data on the drive that I would like to recover that, unfortunately, is not backed up. If I try booting from the optical disk, won't I lose all the data on my HD?

Not at all. If it will boot from the optical drive, you can go to the second page pull down menu > Disk Utilities and see if you can repair the drive.
