Hello,
Hello,
I am in pain, I’m losing it, I started Ubuntu to try to save hard drive data but impossible to find the Windows file; they told me that I had formatted it, ready to give up (I should have), I made a mistake I managed to find a Program Files file, Windows and I told myself that maybe it was in there, I right-clicked and I changed permissions I set read and write I think, and since then I tried to modify (permissions) impossible!!
nothing works anymore and won’t boot, I tried to reboot it says notably could not update ice authority at startup, then error occurred at the startup of the screensaver permission not granted then something like nautilus permission not granted!! I try to go to the recovery terminal and it shows me "to run a command as administrator (user "root) use sudo (command), see man sudo_root for details
bash: /home/max/ .bashrc permission not granted

How to restore permissions to users etc...

    I have a bit of trouble understanding your problem.
    You want to recover data from a Windows partition with the Ubuntu live CD, is that right?

      Well no, I think I just said goodbye to the data on my hard drive now, the problem is that Ubuntu won’t boot at all since I changed the permissions in C:windows, since then it just shows the Ubuntu screensaver with nothing on it, actually I think what I need is to restore permissions to the system, that’s why I’m going into the recovery terminal and I display

      (user "root) use sudo (command), see man sudo_root for details

      bash: /home/max/ .bashrc permission not granted

      is there a way for everything to work normally again

      you understand?

      thanks

      If you haven't formatted your partition, your data is still there. You can't access it from Ubuntu but it is still on your disk.
      I can't help you fix your Linux because the indications you give me are way too vague but I can help you recover them.

      Thank you for your response. The problem is that Ubuntu doesn’t boot anymore since I modified permissions in C:windows. I think it’s because I’m in read-only mode or something like that. For now, before checking partitions or anything else, I’d like Ubuntu to work again and I have access to the information. For that, I think I would need a command to remove the read-only mode and gain access permissions!
      thank you

      C:\Windows is located in your Windows partition, nothing to do with Ubuntu which is on another partition. So that is not the cause of your problem! You have likely modified some of your Ubuntu files without realizing it. To change the permissions on a file you must be able to access it, which is not the case at the moment. The only solution is to use a live CD: boot it, mount your partitions, back up your important data, and then you can try to change the permissions on certain files, but I have doubts about the outcome.

      Hi again, I think I had trouble expressing myself. In fact, Ubuntu was working very well, the live CD and applications were made, but I saw a C:drive Windows folder I think and I wanted to see what was inside. With a right-click I changed the permissions, I must have set read-only and write access! Since then nothing works, I can't connect to the Internet, etc... I restarted the computer and Ubuntu won't start. I think I should modify the permissions in Ubuntu; there must be a command, you understand me?

    Hello,

    The problem is that when typing sudo su and after "chmod" bin there is nothing. I tried chmod 777
    at all it invites me to see a help for chmod, do you know what I should type?

    exactly that’s the question I’m asking myself: what do you type exactly ???

      I had a problem I couldn't access a folder in /usr/local, so I typed sudo chmod 777 foldername and it worked!
