Hello all,

 

I have decided to self-install a Seagate Momentus 750gb internal drive into my early-2011 macbook pro 15" because the original HD was "about to fail" . I am unclear as to the steps necessary , once the new drive is physically installed , to get back to a functioning computer with OS X 10.7 . Can I simply power on and reach this point http://eshop.macsales.com/tech_center/index.cfm?page=HDDppcintelformat/HDDppcint elformat.html ? It seems unlikely to me that a completely blank drive will have Disk Utility ready and waiting on it ? And , once the drive is succesfully formatted , will it be possible to download Mountain Lion using the OS X Internet Recovery ?

 

thank you all ever so much for any and all assistance

    What you should be able to do is Internet Recovery using Command+R+Option keys. This should boot to Apple's server and into their Recovery HD where you can use Disk Utilities and reinstall OS X that came with your machine. Just be sure to have an internet connection.

     

    So, just install the new drive and restart holding/pressing the Command+R+Option keys. Keep them pressed until you see a spinning globe. This is Apple's Internet Recovery and it takes about 5 minutes to boot into their OS X Utilities (Recovery HD).

    You should redownload Lion from the App Store.

     

    1. Easiest would be to have a USB drive enclousure and install system to the new drive while you still run on the old one.

     

    or

    2. Burn the downloaded file onto bootable DVD or memory stick as you will need to boot from something to install the system.

    thx keg55 ,

    just to be clear , even though the new drive will be (i believe) totally blank , i will be greeted upon first starting up with the new drive installed with the ability to connect to Apple's Recovery HD , so long as I have an internet connection and boot up with the command+R+option keys held down ?

    thanks so much

    Yes. You'll see the spinning globe and a progress bar showing you the boot progress. After booting into Apple's Recovery HD, you will see the OS X Utilities menu where you can use DU to create your partition and format it using Mac OS Extended (Journaled) and the GUID partition table (Options button). Then you can close DU and select the Reinstall OS X which will download and install the OS (Lion) that came with your system. I'm assuming Lion was pre-installed.

     

    I have a mid-2011 Mac Mini that was preinstalled with Lion.

     

    Edited: If your system came pre-installed with SL, you will need to reboot with your SL DVD (holding down the C key), use DU to format your new drive, install SL, update it to 10.6.8 then open the Mac App Store and redownload/install either Lion or Mountain Lion whichever you currently have now.

    Your easiest method is to create a USB thumb drive with your current Lion install's Recovery HD using the OS X Recovery Disk Assistant from Apple. Install this on your current system and run the app to create the thumb drive. THEN you can use that to boot into the OS X Utilities menu after you install your new drive. Create the thumb drive and test it first.

     

    I would still do a clone of your current drive if you can. You need some sort of backup so you can restore your data.

     

    If you have a current Time Machine backup with Lion on it, you can boot from that which will provide the OS X Utilities menu so you can format the new drive and reinstall Lion. Boot from this first to test so you understand what I'm talking about.

     

    Edited: I suggest you still try the Command+R+Option keys at boot time to test out and see if you have this feature. I had a late 2010 MBP and after Lion was released, a new EFI firmware update came along that allowed THAT MBP to boot into Internet Recovery and reinstall Lion. The update also provides this functionality to early 2011 models.That 2010 MBP came preinstalled with SL too. So, if you have kept your MBP current with all the updates, you may have gotten an EFI firmware update that allows your MBP to use Internet Recovery.
