windows 2000 server
Their is a software RAID 1 mirror
The disk is set to dynamic

I want to break/remove the mirror and change the disks back to basic

How can I do this?
Will I lose data?

I then want to add a new drive and create a RAID 5 can I do this all via windows 2000?

Thanks

You can break the raid easily.  Just unplug one drive.  The raid controller will warn on boot that it has lost one drive, assuming it has died.  You can bypass this and boot.  However, you can not add that drive and another and build a raid V on it.  You will need to back up the data and start form scratch.  You can't just introduce 2 more drives and tell it to build the single drive image over the 3 drives.  It must be built then copied.  A few more questions:

Is this hardware raid or software?
Why raid V?  Do you do a lot of disk writes?  They will not be great in raid V.  I would recommend getting 2 drives and going Raid 10.  Then you have mirroring and performance (striping).

Sorry, didn't notice the "software" in the title.  Don't think Win200o supports software raid V.  Not that you would want to anyway, the overhead of parity plus the software raid would absolutely kill your system.  I strongly advise against it, if it is possible, I believe it is not.
