[luau] partition problems

[Alvin Murphy]

Looking for help. When I installed Mdk 9 on my Compaq presario which 
came with WinXp on about 19 G HD, I mistakenly gave about 10 or more G 
to linux, leaving only 7 for Win; I went ahead and installed Mdk and all 
is going well, but I do not need all this room and I am running out of 
room on the windows side. I used Partition Magic 7 and went back to see 
if I could fix it, but there do not seem to be any viable options. 
Partition Magic for reasons I do not understand sees the linux 10G 
partition as all  used and I know it is not, but will not let me resize 
it, use it to create another partition, etc.. So I am stuck, unless 
someone knows of a solution, perhaps a linux tool. Thanks
