good morning to all, yesterday I made a mistake: I upgraded el capitan (bootclover) from the app store on my e6420; It appeared to restart the following error and resets itself:
so I decided to reinstall el capitan again, following Jake guide (very helpful by the way) so I downloaded el capitan from the app store but the latest version, and then: the first part of the installation is spun smooth like oil, but on reboot from ssd it was presented the same mistake. Someone has already had the opportunity to confront this problem? and how it has solved? Thanks in advance.
