Hi guys, I´m begginer in the world of macbooks, bought my first notebook with OS X 5 days ago. I have MCB Pro 13" retina, i5, 256gb ssd with El Capitan. Yesterday i wanted to try Boot Camp and run Windows 10. Everything was fine until restart of computer. When I click on Option while booting, i saw just one SSD with OS X and no option for windows. So i ran OS X and ran boot camp again. Follow steps to "uninstall" windows and it works good, said to me, that ssd was merged together again and deleting of windows is complete. I was browsing the internet for a while and then went to sleep. Today, when i came home from work, i opened notebook, but it show me crossed out circle. So i tried to run safe mode, but it showed me screen below. Can somebody tell me what i have done bad and what can i do now ? Already triedrun Disk Utility, but said me that there are no mistakes. Thank you so much.
