Ok, thanks for the help, but....there is another problem:
I defraged Windows partition (I also disabled my swap-file...the virtual memory) about 10 times!
Then I am going to SuSE and I want to resize my windows partition (yast supports this feature, HUURRRAYYY) but then it tells me that it can only resize 35MB(...Please go to windows and defrag your partition...blablabla)
Are there any tools that "really" defrag/resize my windows partition (Open Source)?
(->I tried to use BootItNG for resizing the partition...IT STILL CHECKS FOR ERRORS

....maybe the same defrag-problem?!!)
