Hello,

So i went to boot my imac this evening and it gets stuck on the apple logo. When i hold the option key or the C key it doesn't do anything just brings the apple logo up and sits there. Not sure what to do

Thanks
SHiFT.

Here are some guides on how to replace the HDD, I did it several times with my 2007 iMac and it was okay doing so, but I also build my own PCs in the late 90s.
yea i am a tech so this isnt a problem. I just dont understand why the option key isn't showing me the CD rom and USB that is bootable when i hold it at start up

This is a common symptom of a dead HDD. See it at least once every couple of weeks.

Time to replace the hard drive. Just getting that glass panel off is going to be fun
It's a 2010? You'll need a replacement drive from Apple, short the HDD temp sensor or get a software fan controller otherwise fans run full boar.

I find that sometimes the wireless bluetooth keyboard is not discovered/connected quick enough to catch the "option key" for boot drive selection. If you have a wired keyboard you can temporarily use, that will eliminate that possibility.

There are many threads here discussing the fan issues and how to deal with them when replacing a disk drive if you don't want to use fan control software.

Oh ... and getting the glass front off is the easiest part of working on a iMac. ;)


Good luck ... :)

There we go...you can't boot using the "option" key using a wireless keyboard. It won't let you go into Target mode. You will need a wired keyboard to perform that...If you gonna use a non-Apple keyboard, remember to hold down on the left Alt key to get into Target mode.
