Unable to delete partition now????

Ok, so I installed Yosemite in a separate partition, and it is working fine. So great that I have decided to put it on my main partition and use it as my daily driver. BUT when I go to delete the partition that I originally installed Yosemite on; I am unable to delete it. All the options are greyed out:eek::eek: what can I do???
 
your not inside of 10.10 trying to delete it right? If not, try unmounting the partition first?

I've tried deleting it in Mavericks, Yosemite, and in Recovery, but in all three it shows no option to delete the partition to to resize it.
 
Is anybody able to submit an enhancement request using feedback assistant? There's quite a lot of UI enhancements I would like to submit, but the option is greyed out for me in the menu :(

everytime i go to click the "download yoemtie beta," the page turns into a new webpage, and doesn't open my app store and start downloading
 
Incidentally, I got the email after Yosemite had been installed. hehe. I just got impatient and went to the beta website, where I eventually found my code.

If you haven't received the email just try poking around the beta website, you'll probably find it somewhere.

Go into Recovery partition, but first erase the Yosemite partition, and then you will be able to delete it.

Now I was able to use another thread to figure out how to delete the Yosemite partition, but now I have two Macintosh HD ones, one at the top and one below it indented to the right. On my partitions tab, it shows Macintosh HD and then Free Space. In the second Macintosh HD there is the erase tab with the option to "erase free space" while the option just plain erase is greyed out. Should I try this to delete the "free space" so I can get back to one partition?:confused:
 
Ok, so the "erase free space didn't do anything and now I am stuck with a 50 or so GB free space partition that I can't delete. Any suggestions???:confused::confused:

Use the 2 terminal commands listed in this post, and you will be able to revert your Core storage Yosemite drive and then subsequently delete the partition as you would normally do otherwise.

I actually already deleted the Yosemite partition. I then installed Yosemite on my main partition. But now the deleted Yosemite partition is showing up as 50gb or so of "free space" in the free space format. How would I delete the free space partition????
 
Okay I had to backup with time machine, erase the entire drive, and then restore from that backup. It worked fine and my drive is back to normal; one partition, yeah!

Now I can really start beta testing. WOW does Yosemite look AWESOME!!!:D:apple:
