How to get full ssd back after bootcamp?

Question

macOS

Bootcamp was installed, after which I tried to remove it through the assistant and something went wrong, it seemed to be deleted, but it still occupies space.

through a flash drive with wasps, too, it does not work: format / merge. I tried to boot from recovery which is on the apple website with os lion. There was a cross on the whole screen. Help, I need to somehow fully return 120GB

Answer 1

Run the test using an adequate version of Disk Utility from Yosemite OS
It is available on the network, but if you are too lazy to search, download from here https://www.dropbox.com/s/tjnd26cb7c19zpp/Yosemite...
In the program, select the desired disk, click Check Disk , then repair the disk (Verify Disk, Repair Disk)
Then restart your computer.
Everything will return to its place.
