Ok, this is my problem...
I often reïnstall windowz because the system sucks

, but I still need it

. (let me add that I do mess around with it a lot

). When I want to install windows from the CD I get the following problems

:
- Windows installer hangs on reading harddisk with Linux partitions
- If windows installs, then grub doesn't work anymore
- Windows installation takes way too long
Then I remembered there was something about making a exact 1:1 copy of an harddisk or partition

. So I went looking for a program, but that turned out to be quite hard

.
Question: Where do I find a program for Linux that can create AND restore NTFS partitions?
I tried with mkisofs

, but I don't quite understand that

. Plus, I think that the Windows NTFS is violating a lot of ISO laws

.
