I have made a change to GRUB2 bootloader in etc/default/grub.
Now I need to run 'update grub' for the change to take effect.
However, the 'update grub' command on the terminal is giving this error message:
root@debian:/# update grub
bash: update: command not found
Can someone please explain why this command is no longer working?
I've had to make a change to grub because I tried to install a new distro which meant I had to alter grub.
The install wasn't successful so I deleted the grub file and then re-installed it.
The re-installed grub needs a change so I can get sound on my pc.
However, I can't add these changes because the 'update grub' command doesn't work.
I've checked the grub file with another debian distro and they are both the same.
So now I don't know if I need to check if a different grub file is the problem or anything else.
Can someone help?
