I have dual booted Ubuntu 20.04 Desktop alongside Windows 10. I had made an un-allocated partition of ~270GB on my Samsung 860ev0 500GB SSD for installed Ubuntu. I have installed Ubuntu successfully, in fact i am writing this question on Firefox on Ubuntu. But, when i check it on disk management on windows, that partition i had made is still un-allocated. Here is the result of "df" command of my terminal, results of which made no sense to me whatever.
Will you please help me figure out if I have installed Ubuntu on that partition!. And if I have not installed it on my SSd, will you please also point me to an article that shows how to install it on unallocated partition of my SSD and not on HDD.
FYI, I also have a 1 TB Western Digital HDD(NTFS formatted) in another slot of my laptop.
EDIT 1: here is the screenshot of Gparted for my SSD. I presume this means I have installed both operating systems on my SSD. Correct me if I am wrong.
