How do i remove the default GRUB2 menu entry for Windows?

[Browser]

Hi everyone,

I duel boot Fedora 16 and Windows 7 and i use GRUB2.
I've managed to remove the defualt GRUB2 menu entry for linux with "chmod -x 10_linux",
and make my own custom GRUB2 menu entry for "Fedora 16 GNU/Linux".
However, I don't know how to remove the default GRUB2 menu entry for Windows 7.
Can anyone tell me how to remove the defualt GRUB2 menu entry for Windows?

Currently, i have the default Windows 7 entry commented out in the 'grub.cfg' file
so that i can use my own custom GRUB2 menu entry, but i find this to be an unsatifactory
solution.

Thank you.
Regards, Browser.

You can try adding

GRUB_DISABLE_OS_PROBER=true

in the file /etc/default/grub, then running


grub2-mkconfig -o /boot/grub2/grub.cfg

Sometimes, however, this results in grub not looking at the custom configs too--however, I've only that problem (of it resulting in grub2 ignoring custom configs) with Ubuntu, not Fedora.

The grub2 script file /etc/grub.d/10_linux is responsible for determining your current Fedora kernel entries in the menu.
The grub2 script file /etc/grub.d/30_os-prober is responsible for pretty much everything else, including Windows and earlier versions of Fedora that might be present.
You can modify the 30_os-prober to exclude adding any or all Windows (NT and up) OS's, like so:

Find the entry, should begin around line 98 in the file:

  if [ -z "${LONGNAME}" ] ; then
    LONGNAME="${LABEL}"
  fi

And right below it, add the following, where /dev/sdxx is your W7 bootable drive/partition:

  if [ "${DEVICE}" = "/dev/sdxx" ]; then
  continue
  fi

I do this to good effect to keep a long unused W2K install on one of my 3 hdd's from showing up in the grub2 menu. The only caveat is that by manually editing any of the script files in /etc/grub.d/, when there is an update to grub2, you're edited script file will be preserved as "30_os-prober.rpmsave" and a new "30_os-prober" file, without your edits, will be installed. Both will be executable and so both will run, regardless of the name change, when you subsequently run a "grub2-mkconfig -o /boot/grub2/grub.cfg" command.

To prevent that being a problem, you then need to either apply your edits to the new "30_os-prober" file and either delete or unset the execute bits on the "30_os-prober.rpmsave" file, or unset the execute bits on the new "30_os-prober" file. A minor annoyance, but then, grub2 doesn't get updated all that often, at least not yet.

I can't put my finger on the Ubuntu guide at the moment that gave instructions on how to do what I just described, That guide contains a wealth of information. I thought I had it bookmarked...oh, I'm chrome, it's probably in my FF bookmarks.

If I may have misunderstood you and what you mean is that Windows is the "default" OS at the grub2 menu (top of the menu list) and you wish to have another OS as default, and NOT to remove the Windows entry completely from the grub2 menu, then ignore the information I gave above.

There are a couple of different methods to make any one of the grub2 menu entries the "default". Please state more clearly which it is you're trying to accomplish.

Hi smr54 and PabloTwo,

Thank you both for your response to my post.

PabloTwo: your solution did the trick for me.
The link you gave turned out to be a valuable resource.
