It will be interesting if someone does know tis for I have the same problem - the only difference being that it was Ubunto that I got rid of. Now my hard disk on the XP machine insists on installing under the 'G' letter - this makes some games unplayable (notably Codemasters Toca 3 - much to my annoyance!) Apparently, this program wants to see the 'C' Drive and, of course, you cannot change the drive letter on this drive. As the machine is over 4 years old I have thought of renewing the hard drive itself. This is a problem you don't see every day and it is doubtful if anyone knows the answer I'm afraid. But, you never know, there are many talented users of this forum and, if they can help then they undoubtedly will!
