Hi, welcome to justanswer.com! My name is Mike.I am going over your question and I will be with you shortly.
Can you boot to Internet Recovery? Command Option R
OK then I suggest you erase the drive and install new system, make a new test user account then upgrade to the latest system version if needed and then use Migration Assistant to bring your account over from your Time Machine backup
Right but use Migration Assistant do not restore at the end of installation.
Sorry I don't understand that.
So you booted to Internet Recovery erased the drive and then installed Mountain Lion? Did you choose the device to erase and not Macintosh HD as I instructed? What happened after that?
So is that what you did or not? I am still not clear... can you explain in more detail? What did you do and what happened and in what order? Remember I am not in front of your computer. I have no idea what procedure you followed at this point.
When you booted to Internet Recovery did you choose the whole device to erase not Macintosh HD. The very top item? You have to erase the whole device because you have a newer Recovery partition installed
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
6. Press and hold the Command-Option-P-R keys before the gray screen appears.
7. Hold the keys down until the computer restarts again at least twice.
8. Release the keys and immediately hold Command - Option - R
When you get to Disk Utility choose the very top item on the left (not Macintosh HD) and then name it Macintosh HD and Erase. Then quit Disk Utility and install.
Yes it could be named that
You select Erase and you rename it
Please tell me exactly what you did. So you were able to Erase and rename it Macintosh HD then you installed? Restart and hold the Option key until you see a list of boot partitions. Do you see Macintosh HD listed? If so choose it to boot from
I don't see how you could have installed that fast it has to download from the internet ...
OK I have 150MBS and it still takes longer than that normally, wierd... So did you reboot holding the Option key do you see Macintosh HD?
I'm not I just want you to get you up and running. It really would help if you make sure and answer my questions when you reply, thanks good night.
It could not have done that because you erased the drive. See that's what I mean you just told me it finished installing and you had a flashing question mark.. now you are installing again? Did you reboot and hold Option as I instructed? You should just wait for me to reply before doing anything or this will take forever...
I have a feeling you mean it finished downloading and it restarted it did not finish installing right?
WHEN are you getting that did you install it or not or did it just download and restart. If so HOLD THE OPTION KEY. You are only telling me the errors and not what you did....
Let me know tomorrow. I made an offer to do a phone call and I think that will help a lot
