Can't log in! after trying the latest maks hack

I followed the notes an Wehrmacht I logged out to check it ui ended up at a black screen with just the pointer showing. How doin login safe mode doesn't work and it won't display anything. 

You stiil don't get any picture when you launch into safe mode? 

That's correct. Safe mode is the same problem only lower res. 

 

I went home as got an Ubuntu live disk and restored the old .dll's   

 

but I'm still not sure what happened. 

next time, safe mode with command prompt, then just xcopy your renamed files back.

No safe modes will load. networking/command prompt... nothing. I ran a chkdsk, tried again and got the same issue. 

Do You have win 7 on a separate hard drive, SSD or something or even a partition ?

seperate from what? my HDD is in two partitions, one is OS and applications, the other is data.
