Run SFC again as stated in tutorial to see if it can fix any of the bad files.

If not run a Repair Install.

Where did you get Ultimate and how is it activated?

I've had windows 7 ultimate for quite a while now the CD is a bit scratched up so I can't use it

The problem occurred about 2days ago out of the many months I've had this is installed on this PC I went into the log but the list is quite long don't think I can post the results here lol

Is there a way to replace system boot files? What got me stunned is I the files were missing why would the pc boot normally after performing a boot defrag or schedule a disk check and let that run as well I'm really confused i get lucky sometimes as to we're the pc sometimes boot fine with no black screen after choosing start windows normally or last good configuration

I've already done the boot fix using the disk lol and it booted fine but the problem comes back after a restart its almost if one minute everything is ok but after restart the black screen comes back

What boot files and boot fix are you referring to. I've given you nothing for that so far. However if you have any boot problems then a Startup Repair would be in order to see if it finds anything.

If the problem is only 2 days old choose your oldest System Restore Point to try.

I do not use any Cleaning or defrag tools besides the ones listed in Clean Reinstall - Factory OEM Windows 7 which assure you'll get and keep and perfect install.

Please focus on the steps I've given you and work through them until caught up.

Lol no I've done this when the problem started about 2days ago

I have done a system restore problem goes away but re occurs after initial re-start

Note I have done some diagnostics prior to joining this forum but staring from this point I've been following your instructions.
