When you have this error, it means that your system has by default, a line in /etc/fstab which indicates that if there is an error in the file system, that it should go into read-only mode, to prevent further corruption or dataloss.
You could use lsblk to determine the partition name.
Use the command
sudo fsck -f /dev/sdxxwhere “sdxx” is the partition of the hard drive that Linux resides on
Making a file read-only in Windows means you or a colleague are less likely to delete or change it accidentally. This can be helpful if you don't want any unintended changes to client contracts or business invoices. If you need to save changes you can turn off the attribute temporarily, so the protection is limited. Changing a folder's read-only status is less straightforward because Windows Explorer uses the read-only flag to determine if the folder is a system or other special folder, or is customized. Recent versions of Windows, therefore, don't allow you to see or change the read-only attribute of folders in Windows Explorer.
Read-only Files
-
Open Windows Explorer and navigate to the file you want to edit.
-
Right-click the file name and select "Properties."
-
Select the "General" tab and clear the "Read-only" check box to remove the read-only attribute or select the check the box to set it. Click "OK" to save your changes.
Read-only Folders
-
Click the Windows "Start" button and type "cmd" in the Search field.
-
Press "Enter" to open the command window.
-
Type the following command to remove the read-only attribute from a folder:
attrib -r drive:\path\foldername
Press "Enter," replacing "drive," "path" and "foldername" with the full path to the folder you want to change. Use the equivalent command, replacing "-r" with "+r" to set the folder to read-only.
-
Type "exit" and press "Enter" to close the command window.

Read-only is a file attribute, or a characteristic that the operating system assigns to a file. In this case, read-only means that the file can be only opened or read; you cannot delete, change, or rename any file that’s been flagged read-only. To change the read-only attribute, follow these steps: Right-click the file or folder icon. Remove the check mark by the Read Only item in the file’s Properties dialog box. The attributes are found at the bottom of the General tab. Click OK. Likewise, you can set the read-only attribute by placing a check mark in the box. This ensures that the file cannot be changed or deleted. Well, it can’t be changed or deleted until someone removes the read-only attribute again. Files and folders you copy from an optical disc may inherit the read-only status. That’s because a CD-ROM or DVD-ROM is Read-Only (RO) media. After a file is copied from the optical disc, however, you can change its read-only status as described in the steps.
The solid Read-Only check box in Windows 7 and Windows Vista refers to the file’s or folder’s permissions. The box may indicate that read-only permissions are set for other users on the same computer.
