Disk utility - partition - help needed

[jan_h_clausen]

Hi at some point I made 2 partitions on my macbook pro, one with OS X yosemite beta and one with the stable mountain lion. Now I'd like to combine the to partitions to one (right now they're both 60gb), but somehow I dont seem to manage it. I tried changing the partitions after reboot with apple-R pressed, did not help.
I have spent hours skimming thru forums without finding a solution.

I pasted a picture of how it looks like right now inside disk utility.

Is there anybody who can help me out?

Kind regards,
Jan C,

It appears as if it separated the disk into 2 separate disks, for each partition. I'm not an expert but maybe this is a CoreStorage issue? What happens if you time "diskutil cs list" into the terminal?

Your partition is configured as core storage. Open the terminal application in Applications/Utilities and enter at the command line:

diskutil cs revert /

Reboot your computer and then you will be able to resize the partition again.

Thank you very much, it worked!! I now got access to the whole disk.
Thanks for your help, both.

Kind regards,
