I can add a bootable flag with the a
command of fdisk
.
How to do the reverse: remove the bootable flag of a partition?
You can toggle flag with a
command.
Try the same command again and it will be removed.
If you are not comfortable with the command line may be gparted is better suited for you. Install it using
sudo apt-get install gparted
then open it
Once it is up and running - select the partition and then right click for "Manage Flags". After that you can select the flags accordingly.
