    Problem with disk


    I right-clicked on my C: drive
    I went to Advanced
    I think I went to owner
    I changed the current owner
    Now I can't access my C: drive and I can't change it back.

    HELP! Can anybody help me?

    I'm using Windows 10, Intel I7, 16gb

    Oh dear. This is a situation where you probably need a system backup to recover from

    Backup doesn't work. Hard drive won't let me write to it. It tells me that I have zero space free. Is there a way to change the registry to show a true free space?

    What backup program did you use?

    If you have a Windows Install disc or USB Flash drive, boot off of that and choose your Language, then click Repair Your Computer. See if that works.

    - What do you see when you try to boot your PC?

    If you boot your PC from a live boot disk (which you would need to download and create) - or if you were to extract your disk, put it in a suitable enclosure and connect it to another PC- you could at least take your personal files from that disk and copy them to another disk, assuming you have no backup - which you most definitely should (I've seen people in tears when they have lost material not backed up)- should you need to do a clean install.

    As I've never considered whether you can change permissions on a disk when booting a PC from a live boot disk, I can't comment on that.

    For the future: recommended- Macrium Reflect free/paid+ suitable external storage for image files:tenforums members tirelessly recommend the routine use of disk imaging to provide protection from unfortunate mistakes, system corruption, failed upgrades and unbootable PCs, disk failure... the image files are written to an external disk, and allow you to recover relatively quickly and painlessly, hopefully without technical help.

    If SYSTEM does not have permissions, the disk will show as empty.

    Either format or reset permissions.

    Try to match up your Permissions to look like mine:

    My system doesn't let me do anything with permissions. It freezes up temporarily.
