Sorry if this topic has already been covered but I searched around and couldn't find anything that helped/made sense to me. I've never used ubuntu so I have no idea what i'm doing (sorry) but heard it could be used to recover files.

So I installed ubuntu onto a USB using another laptop, booted it from my laptop, selected "try ubuntu".

Now I want to access my files on the hard drive, but when I click on my hard drive it comes up with an error message saying "Unable to mount location. Adding read ACL for uid 999 to ' /media/ubuntu' failed:Operation not supported"] (*,)

Would really appreciate some help from a more knowledgeable person than myself
