Do you know what version of Mac osx you have installed? Snow Leopard, Lion Mountain Lion, Yosemite, Etc? ( 10.6 10.7 10.9 10.10 )
Also, do you have an install disk that matches your version of mac osx?
Ahh.. Ok, lets try some steps that may work. Then we will move on to the harder stuff.
Lets start here.
Shut down your Mac.Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.Turn on your Mac.Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.Release the keys.
Will it boot past the no entry sign now?
If not, lets try this next. Shut down the mac, start it and immediately press and hold the keys below.
The Mac will now start in OS X Recovery mode. In recovery mode you should be able to choose reinstall osx.
I just seen your request for a phone call, which will cost more. Id like you to try the above steps first and see if they work, ( and save you the extra $$ for a phone call ) and if they dont then we can move to phone support.

Thats an improvement. lets try this, in the osx utilities window do you see where it says reinstall osx ?
If so, click that and start the reinstall. if not, then click utilities, then click disk utility.
Then click repair disk permissions first. Once that completes, go back to disk utility and click repair disk next.
When that completes restart the mac and let it try to boot normally. What happens then?
Perfect. lets put the phone call offer on hold for now.
I will be online till early evening. Please update me when the install finishes, or fails. Whichever comes first!
Apologies for the delay, your message came right after I left for my lunch break. Ive just returned and read it.
I am here now. What happened with the OSX recovery?
Hi, I never heard back from you after you told me there was 48 minutes remaining on the OSX recovery..
Is the mac working now?
