Got a situation/problem/stupid question. Most of the dual boot questions and answers are Windows/Linux ones. I am dual booting Ubuntu and Linux Mint. I have played around with Mint for a while now (nice OS) but want to replace it with another OS. It is already on a flash drive and I started to install when I got to the what do you want to do page. I choose something else but was then forced to look at what I call the dreaded colored lines page. If all I want to do is replace Mint with another OS what do I do. Do I have to change boot or create a new swap file? Will it use the old one that Mint created? I have attached a screenshot of gparted in case anyone decides to take pity on me.

You don't need two swap files.

Each install can use the same swap file.

The boot flag is meaningless, it does not matter if it is on or off.

All you have to do is to select manual partitioning, then choose the partition that you want to over-write and set it as /.

Secondly, you can either pick the Ubuntu swap file ( which will probably format it and change the UUID so you will have to edit your Ubuntu /etc/fstab file,) or you can install with no swap partition and later you can add the line concerning the swap partition from the Ubuntu /etc/fstab to your new install's /etc/fstab.

You can certainly delete the other swap file and merge it into one of your partitions.

Thanks. I got the solution and successfully installed one system over another. I just get apprehensive when I have to deal with gparted. It is really simple but you know about us new guys. We stay new guys for a very long time.

You're welcome.

Glad to be of help.
