health warning:
On the occasions that a windows partition has not been recognised, or 
has not been accepted readily by say, gparted, I have found that there 
have been some sort of problem with the windows partition or the 
filesystem. At worst, the disc itself was giving bad sectors. I hope 
this is not the situation for you, but if it is, make sure your 
important files are backed up well (twice) and, from windows do 
standard stuff like checkdisk (chkdsk?) maybe do this more than once. 
If the apparent ubuntu trouble then persists then  make efforts to 
check the HD itself - if the ubuntu live cd runs ok then in live 
session , use the 'disk utility' to show its health

good luck
