Q: Reinstall Mac OS X Without Recovery Mode | Mac Doesn't Boot Normally

You said I'm able to unlock the bad Mac's drive via Disk Utility from the good Mac.

After I unlock it using Disk Utility on the good Mac..

Does that mean if I enable Recovery Mode on my bad Mac, will the disk appear unlocked on my bad Mac (In Recovery Mode)?

Or will it still be locked on my bad Mac and/but only appear unlocked on the good Mac? -- Don't mind this if you don't understand.

Hope you understand.

How did you install the OS X Mountain Lion?

Did you install the OS X like how it's done on the link Esquared gave me?

Will erasing the disk unlock it?

If so, can I unlock it without erasing?

Then after unlocking, I will reinstall the OS X.

I'm sorry but I'm confused by all your questions.

 

You mentioned in one or your prior posts... "But the disk is locked and I can't reinstall the OS X.".

 

Also, in that same post you mentioned... "Recovery Mode does work and I can enable it..".

 

I don't know what to tell you anymore.

Okay..

So I turned on my Mac and enabled Recovery Mode.

The window Mac OS X Utilities appeared.

There are four options I can select.

I selected Reinstall Mac OS X.

At the end of the process/instructions..

It told me to select a disk where I want to reinstall the OS X.

Two disks appeared: Recovery HD and Macintosh HD

Both disks are locked.

So now I'm trying to unlock the disk using the good Mac..

Which you said, "You should be able to unlock the Mac's drive via Disk Utility from the good Mac" - 10:36 AM Response).

So that after unlocking it, I'll reinstall OS X with only my Mac (Without Target Disk Mode).

If what I said above doesn't work..

I'll reinstall it with Target Disk Mode.

Sorry for the confusion.
