Do you have a separate /home partition? If so /home in your installation should be empty, it's for mounting home partition as defined in fstab.
"chown" in a live session would not know your_username:your_username (1000:1000 should work), e.g.
- Code: Select all
chown -R 1000:1000 /where_your _home_partition_is_mounted/your_username
