I have a macbook pro with two partitions:

1. Mac OS partition (200 GB).
2. Linux partition (100 GB).

When I enter the recovery mode and open the disk utility, and click "partition" on my whole HD device, I can see a pie chart showing each partition and its size.

My goal is to delete the linux partition and get back to the normal state where my mac has a full 300 GB of storage instead of 200 GB.

My question is: If on the pie chart I clicked on the linux partition and clicked the minus "-" symbol, will it achieve my goal?

Is it going to delete my linux partition and give its size to the mac without losing any data on my mac partition?

Please help.
