Delete hard drive partition

I followed the suggestion to no avail. In Disk Utility I select the disk to be erased, press erase, the icon of the hard disk on the desktop becomes white for a few seconds but reappears. The minus sign in Disk Utility under the tab Partition does not highlight. The unwanted hard disk occupies all the memory I want to be available for the main disk. If I try to resize this memory, it creates a new disk.

Highlight the 2nd partition, erase it, then highlight the hard drive, click on the partiton tab and highlight the 2nd partition and press the minus button.

You're welcome.

Thanks, Lanny. Very clear answer, worked great, took me about 2 minutes. iMac with 10.8.5.

Thanks Lanny... 🙂

So this will work if I create partition with a bootable version of a different OSX? From a couple of things that I read in forums it seemed that a "GUID" partition may not operate this way, i.e. that I would need to erase the whole HDD of I wanted to remove it.

PS I want to do this for a beta version OS.

Not sure what you're looking for as this post was originally about removing a partition.

However, you can have multiple boot partitions with different OS X versions on the same drive. If you have enough space, you should be able add partitions without having to erase the whole drive. I understand that there are limitations when one of the partitions is a bootcamp partition.

Hi,

It said that it was unable to "Unmount the Disk" but I was about to delete it. I just can't do the other part. Help!!

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it. You can link to this one.

Dear Lanny

Was quite worried how to get rid of the second partition I had created by mistake . Your solution was

- Easy to understand

-Simple to execute

- Took the least of the time

- AND Solved the issue

Thanks a ton

I tried installing bootcamp then got stuck and gave up. I then tried to remove bootcamp and the partition it created, but an error message came up during the process and said there was an error removing the partition. The programme ended up closing and now I am left with an empty partition which I can't figure out how to delete. Any thoughts on how to fix this?

For people who can't delete hard drive partition (can't press the minus button). Try restart and do it again, you will see the magic. It's work for me 😉
