cj95 Posted May 28, 2009 Share Posted May 28, 2009 I never had this problem before ( i used to install fine some time ago on the exact same computer) but right now I decided to install it again , and every time I go to disk utility , I press erase(extended journaled ) and it doesn't do anything. It still reads it as windows file system , and is grayed out on the other partition on the left side, but when I go to windows the partition has actually been erased in the mac file system. the hdd has 4 partitions ( im installing in the fourth) the first partition is SWAP for ubuntu. I have installed ubuntu right now on the fourth) on the 2nd and 3rd is win xp ,any help apreciated Link to comment https://www.insanelymac.com/forum/topic/168284-cant-install-ipc-1056-disk-utility-doesnt-erasemount-the-partition/ Share on other sites More sharing options...
El HaZaRD Posted May 28, 2009 Share Posted May 28, 2009 Partition is must to be a single primary partition. Two or more primary partitions are will be cause this problem.

srs5694 Posted September 16, 2009 Share Posted September 16, 2009 Partition is must to be a single primary partition. Two or more primary partitions are will be cause this problem. This isn't true -- at least, not universally. I just did a test: I created (on Linux) a 3-partition layout on a USB flash drive. This was three MBR primary partitions, one FAT, one Linux ext2, and one Mac OS HFS+. I then moved the drive over to my Mac OS system and reformatted all three partitions to HFS+. The two hard disks on this computer also have multiple primary partitions (they're MBR-only, without GPT). I don't recall precisely how I prepared these disks for OS X installation, but I'm positive that at least one of them had at least two other primary partitions on it before I put OS X on the drive. It's conceivable that I formatted the OS X partition in Linux, but I think it's more likely that I'd have used Disk Utility in the installer. That said, it's conceivable that there are special circumstances in which OS X can't format a second primary partition, but it's certainly not just because the disk has multiple primary partitions.
