How to roll back Ubuntu to a previous version?
I have windows 7 installed on my C drive, ubuntu 11.10 installed on my D drive and then there are couple of more partitions with music n stuff like that. As per the present setting, when I boot into windows7, i am not shown the partition D (which has ubuntu in it). Somehow, the D drive is hidden in windows. Also, when I boot up, I have the option to select the OS i want to boot into :)
Now my questions -
- Why am i not being able to see the D drive when I boot into windows?
- I want to downgrade my ubuntu from 11.10 to 10.04 LTS due to certain reasons. How do i perform this downgrade? I have downloaded the copy of 10.04 in ISO format. I prefer a clean install actually, rather than the downgrade. Please let me know how to keep the windows safe in C drive, and then remove the existing 11.10 from D drive and then install the new 10.04 LTS into the clean D drive.
