With fedora if you want to remove specific partitions from
your disk. Be extra careful because once you have deleted
them it will become extremly difficult to fix.
First if your hard drive has LVM then I suggest you read the
lvm man pages especially 'pvremove' -- remove a logical partition.
Steps for partition removal are asfollows:
First identify the partitions you wish to remove. As superuser
you can run the following command to identify your partitions.
sudo blkid -o list -c /dev/null
or you can run the more modern command of lsblk, again before use
read the man pages on these commands so you understand the format.
Next download from a fedora website "gparted" Gnome partition
editor. This is a gui operated editor and is quite easy to use.
It comes with a good usage manual that you can access from within
the program. Copy this to a bootable cd disk.
If you have LVM installed then you must remove the logical partition
before using the gparted editor.
At this point having removed the required lvm partions then you may
use the gparted programs to remove the selected partitions.
Good luck
