Restore HP Pavillion dv7 with unbootable recovery partition

Hello all,

I have a HP Pavillion dv7 with a 1TB harddisk with the following partitions: system, os, hp_tools, recovery

system
os (empty now)
recovery
HP_Tools

F11 is not working anymore, but the recovery partition is still there..
So I tried to recovery the base.wim file (can be found on the recovery partition) with imagex.

This is working, windows is starting up but gives the following error:

"c:\system.sav\Util\TDCTWKs\hideCMD.vbs cannot be found"...

Did I forgot to extract other important things from the recovery partition? Did I do something wrong?

Thanks a lot!
