the 'du -a' does print the numbers without any units so im not sure how to read it (attach a photo).
and the output of 'inxi' is :
Partition: ID-1: / size: 24.46 GiB used: 22.88 GiB (93.6%) fs: ext4 dev: /dev/sda8
1.by the outpoot of 'df'- it seems that yes.
2. i did the install
3. in mot sure where to check it, i red it is in the 'df' but not sure wich one there...
4.it is dual with windows
