I bought a laptop with DOS and installed Windows in it and then I installed Ubuntu. So, now I am using both Ububtu 16.04 LTS and Windows 10 with Grub2 as bootloader.

But in the bootloader menu "Windows 10" is displayed as "Free DOS"

How can I change "Free DOS" to "Windows 10".

Edit: This is not a duplicate of Editing OS names in /etc/default/grub - where is the OS name read from? since that post only says how the command GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian is used and where does it takes the names from.

My question is different since I want to change the name of Windows OS which has nothing to do with the above command.

Edit /boot/grub/grub.cfg (root permissions needed).

Search for "Free DOS" and replace it with "Windows 10" save and reboot (this is a temporary fix running update-grub the next time may bring back the problem)

For a permanent fix you may want to open a terminal and run os-prober then update-grub and reboot to see if the issue is resolved

    This change will get wiped out the next time update-grub is run. – Organic Marble Mar 15 '17 at 11:08
  • @Organic Marble yes you have a point maybe he should run "os-prober" then "update-grub" that may also work – Ahmed K. Mar 15 '17 at 12:40
  • @Josephson47 what about editing your answer accordingly? –  Mar 15 '17 at 18:17
