To install Ubuntu in a partition on your computer, follow these steps:

1. Download the Ubuntu installation ISO file from the Ubuntu website and burn it to a DVD or create a bootable USB drive.
2. Restart your computer and boot from the installation media. You may need to enter your computer's BIOS or UEFI settings and change the boot order to boot from the DVD or USB drive.
3. Follow the on-screen instructions to begin the installation process. When you reach the "Installation type" screen, choose the "Something else" option.
4. On the "Partitioning" screen, you will see a list of your current partitions. Select the partition where you want to install Ubuntu, and then click the "Change" button.
5. In the "Edit partition" dialog, choose the "Use as" dropdown and select "Ext4 journaling file system". Then, in the "Mount point" dropdown, select "/" to set this partition as the root filesystem for Ubuntu.
6. Click the "OK" button to apply the changes, and then click the "Install Now" button to begin the installation process.
7. Follow the remaining on-screen instructions to complete the installation. When prompted, reboot your computer and remove the installation media to boot into your new Ubuntu installation.
