Since you can't go back into any safe mode you are looking at a damaged OS. Time to salvage what files that are not on backup and restore from your last good OS image.
Yes, we all wish MSFT would have provided a better repair method but they do offer a pay for support system if you don't agree with the do over. Last time round a client paid about 500 for that to save the OS. Can't write it was worth that.

Windows 7 ultimate 64bit with 3 internal hard drives ubuntu 14.04 and windows 8, 8 gigs of ram, intel core(TM) i7-3770 cpu @ 3.40 GHz
I was following somewhere on here how to change fonts on my windows 7 ultimate 64bit and did it through personalize>windows color>advanced and after i did i logged out then back in to see changes but i got a black screen with only my cursor i tried going to safe mode and doing a system restore (because i created a system restore point just in-case this happened) but that did not work and i tried last know configuration which did not work either so what else can i do to fix this?
Thank You in advanced
BTW i can't go back into any safe modes and i tried all knids of scans on command prompt like "chkdsk /f/r" which said it could not fix all of the problems and SFC /Scannow which came out fine still no dice please help.
