My system/hardware specifications are as follows: I lack the "reputation points" to comment there, but wanted to pass on that this worked for me. I was able to restore functionality to Bootcamp Assistant. I am not certain we have the exact situation, but through following/translating advice on another thread, This should now show a partition table with the deleted partition missing. Partition id ('0' to disable) : (? for help) 0 4, then edit that entry ( replace "4" with your entry): This will show your partition table, same as earlier.įind the entry that corresponds to the partition you're deleting, e.g. If you want to keep the hybrid MBR, just not the one partition, begin editing the MBR like so: fdisk -e /dev/disk0 Option 2: Remove only the affected partition (go from triple boot to dual boot or so) This should now show a partition table with the first entry of type EE, and the remaining 3 entries blank. Partition size : (just press enter here to go with the default - the exact number will depend on your disk size) Partition id ('0' to disable) : (? for help) EE You want to replace it with a single protective partition of type EE, covering the whole disk. This will show your partition table, same as earlier. This lands you at the fdisk command line - the parts in bold are what you type.
#How to partition a mac using terminal mac os#
If you want to completely remove any trace of Boot Camp (no OSes other than Mac OS X) you can completely destroy the MBR partition table and replace it with a so-called "protective MBR": fdisk -e /dev/disk0 Option 1: Remove all trace of bootcamp (only boot OSX on this disk) Make sure to substitute the index of the partition to delete (IN THE GPT) instead of "4" and the exact disk you're partitioning instead of "disk0"!įinally, you'll need to delete the same partition from the MBR (you may need to unmount again at this point). Then comes the dangerous bit ( make sure you have backups): Delete the partition using the gpt utility: gpt remove -i 4 disk0 Unmount all mounted partitions on the disk you want to partition, e.g.

If confused, post the output from the above 2 here, and don't proceed. Note the number ( index) of the partition you want to delete in both the GPT and the MBR. Make sure this is the disk you want to change (might be disk1, disk2, etc).

This shows the MBR version (which Windows uses): fdisk /dev/disk0 The above shows the GPT version (which OSX uses).

This happens if you try to partition your Mac disk from Windows. What has likely happened is that the two partition tables, the GPT and the MBR, have gone out of sync. If both versions of diskutil fail here too, stay in the installation media's terminal and get the raw partition table using: gpt -r show disk0 Have you tried booting from OSX installation media? Those have both a Terminal (with diskutil) and the GUI Disk Utility, which might start working as you're no longer trying to partition the drive you're booting from.Ĭaution, from now on: here be dragons! Make sure you understand what's going on before you start on this, you can't back out halfway! Check your backups are readable!
