How to defragment my hard drive on Ubuntu?
My 40 GB hard disk is partitioned as C and D, 20 GB in each. I have installed Ubuntu in drive D, after installing Windows XP in Drive C. Grub first loads Ubuntu. How to change the order so that the default is Windows XP?

change this part here
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0
remove the 0 and put 6 in its place. it should be like this
## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 6
u will have to do this as root. to do it type in a terminal
gksudo gedit /boot/grub/menu.lst
make the change and save. now grub should boot windows by default.
one thing though. i do not know if adding a new grub entry or removing one will change the "default 6" accordingly to lets say "default 4" if u remove one of the kernels u have now. in case it doesnt change it automaticaly do it manualy by counting the menu entries. now u have 7 entries so the last one is number 6 because the count starts from 0 (u can tell which lines are entries if they start with the word "title"). hope that this solves ur problem!
cheers

In Ubuntu you don't really have to worry about this, ext4 takes care of most
of defragmenting problems so you should be fine for the most part.

There are lots of Linux users who don't care how the kernel works, but only
want to use it. That is a tribute to how good Linux is.
