So, I recently began receiving this problem which disallows me (although I'm admin, and the only user account on the computer) from creating, moving, or accessing anything within the hard drive. I am also unable to download anything. I'm still able to access stuff outside of the hard drive, but only access. It's been very frustrating trying to do anything on my computer, and sadly I can't take a picture because my computer won't let me save anything. I've also tried doing a few things, one of them going into safemode and trying to grant me ownership, although I wasn't able to check off the boxes. I've also checked for viruses, to no avail. As said before, my computer won't let me download or install things. If anyone knows how to solve this, please inform me- thanks.
