Hi,

I am sorry to hear that you are having the same problem, unfortunately i could not fix my problem, nor was i able to find any valuable info on the web to help with my troubles, so the only thing that i did was to delete my ubuntu OS and reinstall it, i.e. deleted the partition from wndows and did the whole thing over again thereby losing all my data. Sorry I cant help you. good luck. p.s. since then i decided to part ways with both Linux and Microsoft!, and bought myself a mac!
