Partitioning in Bootcamp using Mountain Lion

When trying to download Mountain Lion, I was given an error message that stated that there was a conflict with Bootcamp. I went to Disk Utilities and Erased Bootcamp, hoping that would solve the problem and was correct. However, now that Mountain Lion is downloaded, I have Bootcamp as a slot appearing like my Harddrive, but there's no information. When I try and partition again to download Windows 7, I'm given an error message "The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows."

How do I do this?

Yes. Is there another way to do that?

The clone needs to be on an external drive.

I suggest that you get one, you need an external drive for this, and for longer term backup.

I ordered an external harddrive and it should be arriving this week, so looking forward to getting this problem fixed.

Hi Dan,

Welcome back 🙂

OK, time to clone your internal to your new external, I have already covered that but if you have questions .......

I'm getting the same error message (MBPro Retina/250 GB SSD).

I have only one partition, Macintosh HD, on the SSD, and it's the full 250 GB, although 40 GB is available.

Actually, C, I do have questions - just want to make sure I do everything right this time. Just take me through how to format the external harddrive, then we can take it from there. Thanks

Connect the external then open Disk Utility, Select the external in Disk Utility and choose Erase, give the volume a name and choose Mac OSX Extended (Journaled) as the format. Check that you have not inadvertantly chosen your internal, and erase.

I see the main name with "1 TB" in front of it, then a LaCie, then LACIE SHARE. I know the first is the overall name, then the other two? You mentioned not choosing the internal - is that the LaCie or the LACIE SHARE?

Dan, how can I know what you named your drives (and if you really can't figure it out stop at once)

You have 2 drives, internal and external, if you can't reliably tell one from the other stop what you are doing and take the whole lot to an Apple Store or an AASP. I do not joke here, you must know which is which when you make the clone (or you could copy the empty drive to the internal by mistake.)

I haven't renamed anything. When I registered the external it backed up my main harddrive which gave the second name to the Lacie named LACIE SHARE. That's why there's two on the list in Disk Utility. I was trying to find a way to copy and paste the image from Utility but, OS 10.8 made Photoshop obsolete.

I thought you were cloning (using CCC) the internal to the external drive?
