How to delete windows 2000 professional

[dick2000]

Hello,

I have four windows installations.
2 xp one does not work
2 win 2000 one does not work

How can I delete the bad xp and 2000?

Will I lose any data?

Are they all on the same drive?
Different partitions?
Different drives?
What do you use for a boot manager?
