Windows 10 won't boot, Bad System Config Info, friend messed with msconfig

[zma1013]

My friend recently changed some settings in his msconfig file on his Windows 10.  He went to the Boot tab, then to Advanced Options, then changed number of processors from 1 to 4, and then he also check marked the maximum memory box.  After this it would not boot correctly and it stalls at a screen showing "System Code: BAD SYSTEM CONFIG INFO"   System Restore won't work because it says their is no administrative account for some reason.  Can't get it to boot into Safemode either.  System Repair doesn't do anything.  I looked around and some things suggest doing something with the command prompt or bcedit but I wanted to ask about the problem first.  Thanks for the help.  We believe the msconfig change may be the problem but aren't exactly sure and were trying to figure out a way to fix it back.
