Dual Boot Disk Permission Problem

• If you use dual boot computer with Windows and Linux, and you faced some problem in disk permissions on Ubuntu while trying to reach the disk’s content of Windows (Can’t Write, Read Only!!!), you should follow the steps below:

• Go to, Control Panel

  Hardware and Sound

  Power Options

  System Settings

  Choose What the Power Button Do.

• Then click on Change settings that are currently unavailable.
• Under the Shut-down settings, uncheck Turn on fast start-up (recommended) option.
  • Why we’ve done this is to prevent Windows to take control of the disk before Ubuntu while opening. Thanks to this, Ubuntu will get the control on disk and will not be facing any permission problem while writing.
• If the above itself is not working, go back to your beautiful :) ubuntu system.

Resolving “Read-only file system” Error

The error Read-only file system indicates that the file system mounted at /mnt/XXX/ is mounted as read-only. To change the permissions, follow these steps:

1. Check Current Mount Options

mount | grep '/mnt/'

2. Remount the File System with Read-Write Permissions

sudo mount -o remount,rw /mnt/XXX/

3. Change the Permissions

sudo chmod ugo+rwx /mnt/XXX/

4. Verify the Changes

ls -ld /mnt/XXX/

Possible Issues if Remounting Fails

• The underlying device does not support read-write operations (e.g., a CD-ROM).
• The file system is configured to be read-only in /etc/fstab.

Check /etc/fstab and ensure that the file system is not explicitly set to be read-only. If necessary, edit the file to allow read-write access:

sudo vi /etc/fstab

Find the relevant line and change ro to rw. Then, remount the file system again:

sudo mount -o remount /mnt/F272D12672D0F079/
