After clearing the bin the PC runs slow

Yes, now its on E:

I just checkt now with "diskpart" "list Volume"
and now it says
Volume C is the System reserved Partition
Volume E is the "Original" C: Partition
Volume D is the "Original" D: Partition and
Volume F is the "Original" E: Partiton ("Original" refers to the time the PC worked without problems)

So "system reserved" is the ONLY active partition?

Code:

diskpart
select vol e:
active
exit

If that was succesful .... reboot again to recovery environment and perform a startup repair and post results.
Does system boot normally afterwards?

O sorry... I thought it wasn't booting and showed boot0: error?! It was in your post!

Anyway....

Code:

diskpart
list volume
----which volume letter is system reserved now? Assume P. Replace with actual found colume letter!
select volume P:
active
exit

Reboot normally.

So it's not a boot problem at all!!! What a waste of time. We could have done all actions in win7 itself!

It means the ACTIVE partition is missing some files. Don't know why. You even did mark the other partition (then called E) active, then rebooted from DVD again, ran "startup repair" .... it produced the same message. Close to impossible.

The partition table does not have a valid System Partition.
The system partition listed in the partition table does not contain the required system files.
