Because "drive C" is a partition, not a whole harddrive.
You need to go to management - disk management.
To get rid of grub, use your xp cd and the "recovery console" to do
a "fixmbr" which will boot the windows bootloader in place again.

You can use disk management in XP to delete all ubuntu remainders and create
one partition adjacing to your c: which will then have driveletter d: or
another - but with XP onboard tools it is not possible to add that space to
c:
In fact, using a 2nd partition may be a good idea: you can right-click
on "my files and settings" folder and choose to move it over to the 2nd
partition. Windows and office programs will recognize that change and
behave accordingly. And, you won't lose your documents even after following
Dan C's advice

or after your windows got b0rken (once more) and you had
to reinstall.
If, however, you insist in adding that space to C:, fire the ubuntu install
dvd/cd in livecd mode and use gparted there.
