    Hi all

    I'm having grief trying to create a new windows partition on my MCP. This is a similar problem to a million others that i've read on google, but slightly different and I cant get to the bottom of it.

    Soooooo, I had a 100GB hard drive running 10.5 and created a 20GB partition for XP. All good, all worked. But 20GB wasnt quite enough so I purchased a new 160GB drive and used Carbon Copy Cloner to create an exact copy of my OS X partition on the new drive. Removed old hard drive, installed new one and OS X runs like a dream still.

    However, now I go to make my windows partition using bootcamp assistant and get the following error:

    "The startup disk cannot be partitioned or restored to a single partition

    Back up the disk and use Disk Utility to format it as a single Mac OS
    Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."

    Thing is, there is only one partition on my drive when I look in disc utility. I could just format the drive and restore using carbon copy cloner I guess, but I'd like to avoid that hassle. Anyone got any idea why Bootcamp thinks the drive cant be partitioned???? I'm lost.......

    I was seeing the same thing when I replaced my hard disk. The problem turned out to be that I didn't set the Partition Map Scheme to "GUID Partition Table". You can check in Disk Utility by selecting the drive (not a partition) and in the lower right corner you should see the scheme.

    If that is the problem, then you will need to boot off the old drive and start over. As I recall, it is the erase option in Disk Utility that allows you select the partition scheme, but I could easily be wrong.
