So I had a system that dual booted with windows 7 and ubuntu. I wanted to get rid of ubuntu and install debian. So I got the iso and went through the install. When I got to the part where I partition my HDD I told it to erase the part with ubuntu and to then use it to install debian. It said it did that. I finished and had my debian install up and running. I have the grub that allows me to choose between debian and windows. When I went to boot into windows the boot loader there still gave me the option to boot into ubuntu. I thought that was weird since debian said it wiped that part of the disk. I booted into ubuntu and found that it was on the same partition as debian. I could access all the debian files. Yet it had it mounted as if it were a separate disk.
What happened? Am I totally wrong in thinking that the installation should have formatted the partition before putting debian onto it? How can two distros run on the same partition? Also, when I checked the disk space with df -h I found that even though ubuntu and debian were on the same partition they reported different amounts of new and used space (same total space)?? I'm bewildered and I don't know what to do now. I just want ubuntu to go away. What do ya think?
Thank you, Bob
