I don't know match about Ubuntu ... sorry if my question is stupid :( I try to google it - but still does not understand
I hold DVD with Ubuntu 16.04 and i have machine with 500GB I want to install Ubuntu on as the first operation system ( i need to setup 3 linux destrabution ) on the first 100GB of the disk.
On the installation i have the display of the partition - and where i want to install the Ubuntu - but i don't understand what to fillup here.
For Ubuntu just follow the steps provided in the community's wiki, as provided by Mikewhatever in the comments. Choose the "Something Else" option. Make sure you make a Swap partition. You only need one Swap partition. Your other Linux installations can use the same Swap partition.
When you choose something else as the install option. Follow the prompts to make the 100Gig partition you have set aside the root "/" partition. The partition should be formatted as ext4. During the install you can checkmark format as one of the options for that partition.
The installation is quiet seamless. I can't speak for the other distros, but I'm sure you'll see something similar when running their installation process.
