I have Windows10 in my HP laptop. Also I have 500GB HDD. I partition this HDD in windows10 and make three 100GB partition , all are in NTFS . Then two days before I install Ubuntu 18.04 LTS in my laptop. This partions are seen by clicking in other locations tab in ubuntu , it is shown as /dev/sda5, /dev/sda6 and /dev/sda7 . Yesterday I successfully create folder on /dev/sda5 by right click . But today I am unable to create new folder ( either by right-click or by ctrl+shift+N ) . What can I do ?

  • Yesterday I create a folder **Main** in \dev\sda5 . I enter into "Main" folder, there also unable to create new folder . Also select any document inside the "Main" folder, right-click on it , then I see that **cut**, **Move to** and **Rename** options are inactive. Why this happens ? – Bapi Saha Apr 02 '19 at 16:27
  • You can just do `mkdir "name of the folder"` simply to create one – Tintin Apr 02 '19 at 16:40
  • @Tintin I want to create folder of name 'abc' bu using "mkdir abc" in terminal , but this will give the following message : "mkdir: cannot create directory ‘abc’: Read-only file system" – Bapi Saha Apr 02 '19 at 16:57
  • So you see that's the major problem which you should've mentioned in the post itself – Tintin Apr 02 '19 at 17:00
  • @user68186 Yes problem is solved , thank you so much . – Bapi Saha Apr 02 '19 at 17:10

The problem is caused by Windows 10 default fast Startup setting.

Boot Windows

Turn off Fast Startup in Systems Settings:

  1. Open the Control Panel (icons view), and click on the Power Options icon.
  2. Click on the Choose what the power buttons do link on the left side. (see screenshot below)

enter image description here

  1. Click on the Change settings that are currently unavailable link at the top. (see screenshot below)

enter image description here

  1. Under Shutdown settings, uncheck the Turn on fast startup box, click on the Save changes button. (see screenshot below)

Boot Ubuntu

The new partitions should now work as expected.

Hope this helps

In a dual boot system, from ubunut itself you can try these two commands to fix the read only error and the associated error of ' cannot create directory ‘path/to/dir’: No such file or directory'

First try remounting the partition(say /dev/sdb2) with write options using the command

sudo mount -o remount,rw /dev/sdb2

If it shows error 'No such file or directory' when you try to cretae new directory, then run ntfsfix followed by remount command(assuming this is the same ntfs partition used in windows)

sudo ntfsfix /dev/sdb2
sudo mount -o remount,rw /dev/sdb2
