FDISK problem with an NT partition

I want to change a laptop from NT Workstation to W98se. I am trying, with fdisk, to rid the laptop of any files and start fresh.

I can’t delete the ext dos partition that was created by NT. It says can’t delete while logical drives exist. If I try to delete the logical drive, it says none exist.

This is 2 gb I want to recover.

If I try to install 98se, it tells me there is a partition created by NT that will be unavailable.
