BJMoose Posted November 4, 2007 Share Posted November 4, 2007 Try using fdisk. One of its options is to erase all non-dos partitions. Then you can start all over again. Hope this helps. Link to comment Share on other sites More sharing options...

WHAT HAS TO BE DONE? You have partition magic. You will find in Program Files, Partition Magic an undocumented program PTEDIT32.EXE From Windows XP, start that program. You can use it to manually edit your partition table. Find the partition that is type AF. That is your OS X partition. Change all the values for that partition to 0. Be very careful. If you do this to the wrong partition, you will delete everything on that partition. It is potentially recoverable by recreating your partition table, but don't count on being able to do it. The space formerly occupied by OS X will become free space. You can then partition and format it in the usual way. Link to comment Share on other sites More sharing options...
