IF you did not use the default LVM ( i hate it and don't use it) then it is easy
1) do you want to completely remove win xp
then run gparted ( install dvd or from SystemRescueCd
http://www.sysresccd.org/Main_Page )
reformat the windows drive to ext3
and add it to fstab
example
/dev/sda1 /usr/opt ext3 defaults 0 0
then run
su -
mkdir /usr/opt
and reboot
2) using the LVM
i don't use it so i am not sure .see
http://forums.fedoraforum.org/forum/...98#post1042498
to find out what your install is run
su -
fdisk -l
if you are using a LVM then the output will have something like this in it
Code:
/dev/sda2 14 2237 17864280 8e Linux LVM
