[Leaplist] Unformatting Hard Disks

I am confused.  It sounds like you are saying you have a dual boot system
and want to remove an OS and let the other OS take over the freed up
space.  If that is the case things are more complicated depending on the
OS you wish to keep.

If you just want to un-partition and the re-partition then fdisk is all you
need.  In that case there is no un-partition or un-format.  You just
delete the partitions, make new ones, and format them.  If the new
partition(s) happen to have the same end point(s) your formatting tool may
warn you that a filesystem exists there already but you can just ignore
that or force it to proceed.
