Is there a way I can password protect grub menu entry- e.g. if I dual boot with Windows 7 can I set it so that a password is needed to boot into Win 7?
Secondly I would also like to protect grub menu entries being changed if possible.
thanks
There is a Wiki page on Ubuntu covering all type of password related topics.
Basically, edit your configuration
gksu gedit /etc/grub.d/00_header /etc/grub.d/30_os-prober
Add this at the bottom of 00_header
:
cat << EOF
set superusers="user1"
password user1 password1
EOF
That way the edits will be password protected, with that user and password.
Now, let's protect the Windows entry. Open 30_os-prober
and find this line:
menuentry '$(echo "${LONGNAME} $onstr" | grub_quote)' --class windows --class os \
On that line, add --users
, so it ends like this:
menuentry '$(echo "${LONGNAME} $onstr" | grub_quote)' --class windows --class os --users \
Be careful on not removing the ending slash \
.
Save and close, and then run this on a terminal:
sudo update-grub
You can also encrypt your password with grub-mkpasswd-pbkdf2
. Please take a look at the wiki for more details.
menuentry "${LONGNAME} (on ${DEVICE})" --class windows --class os {
in that file, is this the same? I can't see any other mention of windows in the 30_os-prober
file.
