i checked other questions and found some similar problems but i think mine is a a little different so i wanted to open a new question.
Yesterday i downloaded ubuntu 12.10 with usb and it seemed like there was no problem but when i tried to open windows it gave "a disk read error occurred" error and when i wanted to open ubuntu it gave an error like this
So i couldnt open either ubuntu or windows. Then i searched other questions and found a program called https://help.ubuntu.com/community/Boot-Repair.
I opened it and it worked fine but it gave me an error that there was no space in my partition in which ubuntu was loaded. I then realized my windows partition was full too(they werent yesterday. btw my partition for ubuntu is 35gb and windows for 200+ gb). I also run windows start-up tests but it found no error and i can reach my files in windows partition from ubuntu trial version so hard disk is not damaged.
I need your help i need both windows and ubuntu to work. Thanks
