Hello, I created an Ubuntu bootable usb stick under Mac OS. Then, I removed the Samsung EVO 850 1T drive which has Mac OS and Windows 7 installed. Next, I replaced the CD-drive with a Samsung EVO 850 550GB SSD. I rebooted while keeping the usb stick inserted. I installed Ubuntu into the 550GB SSD. Then, I put the Samsung EVO 850 1T SSD back to my MBP 2010 17". I pressed option while reboot.
I tried all three OS and they are working fine. However, when I pressed option while the computer reboot, lots of icons showed up on the EFit screen. How can I get rid of unnecessary ones? I guess I should only have three icons one for each OS.
