But I'm stuck in installation type no partitions

Please correct this from the partitioning menu.

Correct: Your image shows that you did not define any partitions. Do so, or go back a screen and let the installer do it automatically.

From your image I see an empty drive.

press + to create a partition that should/could be ext4 and mounted on /
press + to create another one also ext4 and mounted /home (so your data is separated from system).

You can go from there...
on sizes:

My recomnedation would be 60Gb to 120GB for /
120+GB for /home (depending on your plans and what you will install)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
