Hi, A little history here, was on the SSD and recently installed the old toshiba (the default HDD) into my 2010 MacBook Pro (found better usage on the SSD so decided to remove it) Apparently I have forgotten the password to my User Account and decided to perform a 'reformat' via Disk Utility. I did it via a USB with El Capitan installed. It has always been fine for me (did the above for 2-3 times for the old MacBooks before giving them away). However, this time, I am repeatedly met with this screen: Can anyone tell me what is going on here? Thanks!
