I had this error while doing a clean install after making a bootable usb (following YouTube instructions) and trying many of the common solitutions. Installing High Sierra 10.13.3 I have a 2012 MacBook Pro
After restarting a number of times with no success, I did the following:
1. Held down Command+R on boot to go into recovery mode.
2. Started the Disk Utility in Recovery Mode and mounted the boot disk. The Disk Utility prompted me for a password for the boot disk.
4. Exited the disk utility, and the recovery program. When it prompted me to select a boot disk, I was able to select the system boot disk and restart.
After the restarting cycle, I get a white screen with a grey “No symbol” (circle with a line through it). What does mean? What did I do? I’m fairly new to the world of macs. Any help would be greatly appreciated. Thanks
