Deleting a Mandrake/Linux partition

[Birdy176]

I had partitioned my secondary 20 MB hard drive into two equal partitions, into one of which I installed Mandrake which never worked. Since then (18 months ago, yes I am the patient type ...) when wanting to boot into WinME, I get the Linux splash screen which defaults into the unusable Linux if I don't quickly scroll down to the Windows choice and click on it.

I want to delete the partition and have full use of the second hard drive (20MB) for my photos in Windows.

How do I go about deleting the partion? My Partition Magic merely tells me that I have two partitions and that only one is available.

Boot with any LiveCD linux distros. Knoppix or whichever....
When it's up, open console and use partitioner
#cfdisk /dev/xxx
where xxx is the partition you want to remove
