13" MacBook, not a pro. Just replaced the hard drive. Was reinstalling the OS and it is not recognizing the Hd to save the OS to... Any insight?
I assume you booted off the install disc? Try opening Disk Utility. You should be able to see the new hard drive there and mount it.
When I click on the HD on the disk utility, clicking the mount button isn't an option. Now it won't eject the install CD
You booted originally off the disc, correct? I don't know of any other way unless the HD you installed had a basic system on it.
