Problems with disk partition

I have Ubuntu on my notebook and want to install Mint too. I've gone through the installation process but when it is time to partition the disk, I get stuck (it doesn't allow me to create the partitions)



Below an image, where I can't partition the hard disk:



enter image description here



I need to finish the installation.

    Maybe a bug or it's a partition type that it cannot detect? If this is the Mint installer, then reboot and try to use gparted in Ubuntu to create and format the partition. Then reboot again and try to manually select this partition in the Mint installer. It's strange that the partition type is not detected...

    In the existing Ubuntu, install gparted, and then shrink the partition /dev/sda3 (it is un-recognised by this partition editor, but hopefully will be my ubuntu). You may need to un-mount it first (that is another question).

You have one encrypted partition on Ubuntu, but as you did not know how you installed it, the easiest way to get rid of it is to:



  • Boot Ubuntu

  • Backup all your data to an external disk in FAT32¹

  • Install Mint; wiping the entire disk

  • Install Ubuntu

  • Restore your backup

Note¹: FAT32 does not allow you to encrypt data, so you won't accidentally encrypt it without knowing

You have no free space, and would need to delete partitions before creating partitions, as you are at the maximum number of primary partitions on a disk.



You have a few choices... if the existing partitions are those that you do not want, you can delete them all, and then start over, use the existing ones, or take the large "unknown" partition and use that one.



You may also want to look up some resources on partitioning ubuntu:
