The POST, in most computers, is a self-test that checks the OS(s) available and boots from the OS selected. POST stands for Power On Self Test. Computers that have an operating system perform a POST before loading the OS, and many imbedded systems also do a POST.

LKGC (Last Known Good Configuration) reverts to the last non-problematic, successful bootup. It is similar to System Restore, but its primary function is to allow the user to use the computer normally, unlike System Restore, which does not guarantee a fix. Also, LKGC is unrevertable, unless you successfully bootup again.
