Problems with merging 2 partitions on El Capitan

Hey. I am running El Captain Beta on my Macbook Pro retina mid 2014. I decided to run windows using bootcamp, and managed to install it. However, i thought i selected the wrong disk to format, so i rebooted my mac. Now, there is a partition that i want to remove, but the thing is that when i read other solved problems, they said to head over to bootcamp. However, my boot camp does not have the 'install or remove content.' So how do i merge the 2 partitions?


Also, i tried using the fsck- fy and the sbin/fsck -fy method, and they did not work

i am already using a 8GB thumbdrive. however, ther is still this error.(sorry for not replying..i was very busy)
