Boot Camp error message: The startup disk cannot be partitioned or restored to a single partition.

I'm trying to partition my HD to instal Windows so I can play some games, but I keep getting this error: The startup disk cannot be partitioned or restored to a single partition.


I checked disk utility - only one partition. Just my mac's HD.


I ran:


diskutil list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

I got:


#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *500.1 GB disk0

1: EFI 209.7 MB disk0s1

2: Apple_HFS Macintosh HD 499.1 GB disk0s2

3: Apple_Boot Recovery HD 650.0 MB disk0s3

samantha-walkers-macbook-pro:~ samanthawalker$ sudo gpt -vv -r show /dev/disk0

gpt show: /dev/disk0: mediasize=500107862016; sectorsize=512; blocks=976773168

samantha-walkers-macbook-pro:~ samanthawalker$ sudo fdisk /dev/disk0


I then used this:

diskutil mergePartitions disk0s2 disk0s3

I got this:


usage: fdisk [-ieu] [-f mbrboot] [-c cyl -h head -s sect] [-S size] [-r] [-a style] disk

-i: initialize disk with new MBR

-u: update MBR code, preserve partition table

-e: edit MBRs on disk interactively

-f: specify non-standard MBR template

-chs: specify disk geometry

-S: specify disk size

-r: read partition specs from stdin (implies -i)

-a: auto-partition with the given style

-d: dump partition table

-y: don't ask any questions

-t: test if disk is partitioned

`disk' is of the form /dev/rdisk0.

auto-partition styles:

boothfs 8Mb boot plus HFS+ root partition (default)

bootufs 8Mb boot plus UFS root partition

hfs Entire disk as one HFS+ partition

ufs Entire disk as one UFS partition

dos Entire disk as one DOS partition

raid Entire disk as one 0xAC partition


I tried boot camp again and same old error message.


What else could it be?

MacBook Pro, Mac OS X (10.6.8)

Did you try to repair the disk in DU?


If you're using 10.6.8 you can boot to the install disc and open DU there. Run Repair Disk and see what happens. Sounds like there could be an error on the hard drive not letting you partition. Repairing the disk could fix this.


Check out this Apple support article:

Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support


I know it's not a start up issue, but the options under the "Try Disk Utility" and "Try fsck" sections may help you out
