i have a two week desktop with 3G RAM and 320G Hard disk. A week ago, i desided to have a partition and alloted 150G to my vista and another 150G for a new OS, Ubuntu.Evrytime i boot my pc, i am asked which OS shall i use. Everything worked ok then, until i upgraded my vista basic to ultimate last sunday. After the succesful upgrade, the pc does not show ubuntu in the boot anymore. worse is my new vista tells me that i only have 80G of harddisk left. What could have possibly went wrong? How do i access my ubuntu again? Im planning to just remove ubuntu to settle to my vista but i do not how. HELP HELP please. Thank You Very much.
