iMac Yosemite Help, install @ 50%

I was reluctant to install Yosemite on my 2008 iMac until now... The install is stuck at 50% on the grey screen with the apple logo. My iMac had been working great in the latest Mavericks, but wanted to upgrade it because my laptop has Yosemite and works fine with it. I have my work backed up on an external Drobo hardrive thank goodness.

This is the second installation, the first one went through, but apps would freeze. I talked with Apple Care last night , we verified disc and restarted the computer holding com.+R. They started me with a fresh download, that was at 10:00pm last night and it is now 5:30pm the next day!

If anyone can help please let me know, I have read many resources online and a lot of it sounds a bit scary! So I thought I would ask here....

You're probably dealing with a drive failure or some other hardware fault. If you still have the original 7-year-old hard drive, the likelihood of a drive failure is almost 100%. Disk verification means nothing.

I am so happy... I kept searching for answers here and found that this worked well... I have my iMac back with Yosemite!

Turned power off. Wait 10 sec. turn power back on holding Com +R. Turn Wifi off. Select restart from menu.

The computer rebooted and finished installation :-))
