I have a mint 10 as well as xp operating system. I double boot the system. All the windows data are stored in the sda1 and sda2. While the mints data are stored in the sda3 and sda5. Well I have to reinstall the mint so that I can change the administrator settings accordingly. So for that while installing from the live DVD I cannot proceed further because it warns me that all the partitions will be erased in order to go with the new installation. How can I do it without harming the other data in the computer. Please do let me know as soon as possible.
