Which partition should I choose to install Ubuntu and uninstall Windows 10?

If you have only one HDD/SSD delete all, go back and select first choice. That'll do partitioning for you.

If you want hibernate / sleep to function, properly do the following.

  • Delete all
  • Create 200 MB mount EFI OR Boot+ESP
  • Create another partition with mount / and leave the amount of ram you have.
  • The last partition set as swap in mount.

Also later on, sudo apt-get gparted this tool will be your friend in the future when partitioning.
