The hard drive in my early-2007 MacBook cracked, and I had to get a new one. I have the new hard drive, and understand how to put the the physical drive into the computer, but I'm not sure how to reinstall OSX Lion without having a disk to reinstall from.I do not have a physical OSX disk though.

I need to reinstall OSX, I have no additional resources beyond the computer itself. I was running 10.7 Lion before it cracked.

When I hold down Cmd+R, I get "BOOTMGR is Missing, Press Ctr-Alt-Del to restart"

The new 2.5" hard drive was used in a Windows machine before the motherboard on the Windows computer was fried, so I removed the Hard drive in working condition, (I have tested it by plugging it into my Windows desktop with a SATA cable and it worked) and deleted everything from the drive. I'm not sure if I have to reformat it, it is currently NTFS, as I was using it as an extra hard drive for a Windows machine. In addition, I cannot retrieve any data from the old hard drive, since the internal disk was smashed. Also, when prompted to pres CTR-ALT-DEL, I have tried both while pressing Fn and while not, and there has been no response from the computer. Please Help!

MacBook, Mac OS X (10.7)

    Internet Recovery isn't compatible with your Mac, so the only thing you can do is to reinstall the original Mac OS X version that came with your Mac, or Snow Leopard (as you have upgraded to OS X Lion, you should have the Mac OS X Snow Leopard disc).


    Anyway, you need the discs to install OS X again, so if you have the Snow Leopard disc, it will be much easier:


    1. Insert the Mac OS X DVD and press C key while your Mac is starting to start from the disc.


    2. Go to Utilities menu > Disk Utility, choose the hard disk in the sidebar and go to Partition tab.


    3. Select the existing partition and press - button to delete it.


    4. Press "Options" button and choose "GUID Partition Table". You need it to install OS X.


    5. Press + button to create a new partition. In Format, choose "Mac OS Extended (Journaled)" and press Apply.


    6. Close Disk Utility and install Mac OS X.


    You can do the same with the Mac OS X DVD that your Mac brought. If you don't have any discs, call Apple to get replacement DVDs for your Mac > Also, you will need to buy Snow Leopard again in order to install OS X Lion

    For some Macs, it can work, but as your Mac hasn't got any operating systems, it will be very difficult or will not work. I recommend you to repair the optical drive in order to install Mac OS X again

    What you're getting is a drive asking for a Windows installer.


    Until that's reformatted as detailed by Mende1, you cannot load OS X on it.


    If you access to another Mac, you may be able to put the MB in Firewire Target Disc Mode and format using DU from the other Mac.

    It may then be possible to use Remote Install (Applications > Utilities > Remote Install Mac OS X) to install from your DVD.


    The crunch is whether the MB will boot to Target Disc without a supported drive being present.

    You'll need the Snow Leopard disc to do the remote install.

    I thought you said your DVD drive wasn't working?


    I can't guarantee an external optical drive will work, because you don't have the correct USB drivers installed.

    I see, I didn't quite understand, I was going to give it a shot with the external one before replacing the internal, but just so I get this staight, your solution is an alternative to replacing the internal DVD drive?


    If it works, yes. What I'm not sure of is whether or not FTDM will work without a Mac OS system on the HD.


    If that doesn't work, then either replace the DVD drive, or remove the NTFS inernal and put it in a suitable enclosure for use as an external drive. You can then mount it on another Mac to do the format and install (from the SL DVD).

    Hi I can't even get to past the first stage as the screen just goes off after a few minutes of the loading screen.

    Any help?
