If you have a windows disk that is an install disk, you should be able to run the setup, and at the point where it asks where to install it, delete the existing partitions, then, choose to install on the drive at which point it should tell you that the partition needs to be created and ask if you want to use the full disk for the OS.

I would advise you install Win98SE rather than trying to upgrade from Win95.

Barring that, any newer windows CD that you have should be able to delete the partitions.

Also, the Tecra is a business series, so, you might have a little trouble getting all of the Toshiba drivers to work on win98 or might have to search around toshiba's site. They have a really good system for finding updates for old machines on their support site.
