    newname="Kubuntu 9.10 Karmic Koala"
    fi


    linux_entry "$newname ${version}" \
    "${GRUB_CMDLINE_LINUX} ${GRUB_CMDLINE_EXTRA} ${GRUB_CMDLINE_LINUX_DEFAULT}" \
    quiet
    if [ "x${GRUB_DISABLE_LINUX_RECOVERY}" != "xtrue" ]; then
    linux_entry "$newname, Linux ${version} (recovery mode)" \
    "single ${GRUB_CMDLINE_LINUX}"
    fi
    Do you know about what line that entry is on?

    Never mind, I found it.

    Re: Grub 2 Title Tweaks Thread

    Do I need to remove "false" from the end of that line?

    Code:
    @Line 143 # "UUID=" magic is parsed by initrds.  Since there's no initrd, it can't work here.
        linux_root_device_thisversion=${GRUB_DEVICE}
      fi
    
      linux_entry "${OS}" "${version_no_generic}" false \
          "${GRUB_CMDLINE_LINUX} ${GRUB_CMDLINE_EXTRA} ${GRUB_CMDLINE_LINUX_DEFAULT}" \
          quiet

    Re: Grub 2 Title Tweaks Thread

    Yeah, you should remove "false"

    It should looks like this:

    Code:
      linux_entry "${OS} ${version_no_generic}" \
    The problem I had was if I updated the variable with the name I wanted, it would leave off "recovery mode" so I did a quick and dirty workaround:

    I had to edit /boot/grub/menu.lst on the BT4 install and then running "update-grub" from Ubuntu 9.10.

    Original menu.lst:

    Code:
    title		Ubuntu 8.10, kernel 2.6.30.9
    uuid		a76c7835-eb6f-459f-a891-496f16bc00eb
    kernel		/boot/vmlinuz-2.6.30.9 root=UUID=a76c7835-eb6f-459f-a891-496f16bc00eb ro vga=0x317 
    initrd		/boot/initrd.img-2.6.30.9
    quiet
    
    title		Ubuntu 8.10, kernel 2.6.30.9 (recovery mode)
    uuid		a76c7835-eb6f-459f-a891-496f16bc00eb
    kernel		/boot/vmlinuz-2.6.30.9 root=UUID=a76c7835-eb6f-459f-a891-496f16bc00eb ro  single
    initrd		/boot/initrd.img-2.6.30.9
    
    title		Ubuntu 8.10, memtest86+
    uuid		a76c7835-eb6f-459f-a891-496f16bc00eb
    kernel		/boot/memtest86+.bin
    quiet
    Edited menu.lst:

    Code:
    title		Backtrack 4 Final (2.6.30.9)
    uuid		8ce79a61-7653-4799-950e-bca17e0b5b77
    kernel		/boot/vmlinuz-2.6.30.9 root=UUID=8ce79a61-7653-4799-950e-bca17e0b5b77 ro quiet splash 
    initrd		/boot/initrd.img-2.6.30.9
    quiet
    
    title		Backtrack 4 Final (.6.30.92) (recovery mode)
    uuid		8ce79a61-7653-4799-950e-bca17e0b5b77
    kernel		/boot/vmlinuz-2.6.30.9 root=UUID=8ce79a61-7653-4799-950e-bca17e0b5b77 ro  single
    initrd		/boot/initrd.img-2.6.30.9
    
    #title		Ubuntu 8.10, memtest86+
    #uuid		8ce79a61-7653-4799-950e-bca17e0b5b77
    kernel		/boot/memtest86+.bin
    quiet
    Here is what my Grub2 menu looks like now:

    Code:
    Karmic (2.6.31-20)
    Karmic (2.6.31-20) (recovery mode)
    Karmic (2.6.31-14)
    Karmic (2.6.31-14) (recovery mode)
    Windows 7 Professional
    Backtrack 4 Final (2.6.30.9)
    Backtrack 4 Final (2.6.30.9) (recovery mode)
    Much, much cleaner.

    Re: Grub 2 Title Tweaks Thread

    I used to have in the previous Grub version an entry for booting USB devices (portable OS's).

    Can I do one entry like that in GRUB2?
    If so, does anyone know where and how sould I add it?

    Thanks

    Probably the best place to add it would be to a custom menu. There is already a blank /etc/grub.d/40_custom file to which you could add the entry. This will place the entry at the bottom of the list. If you want it at the top, rename the file (or create a new one called) 06_custom (the number determines the location).

    As to what the contents of the menuentry would be, if you post your old Grub legacy entry someone should be able to help 'translate' it into Grub2.

    Thanks for the input, I really don't care about the location on the grub menu, so at the end would be just fine.

    In the previous version my USB entry looked like this:

    root: (hd1,0)
    make active: yes
    chainloader: +1


    so if someone can help me in creating one entry for GRUB2 for booting USB devices I would be really thankful.

    Great thread but I'm having a little difficulty with the title of the Recovery mode.

    [LIST][*]If Recovery modes are displayed, make the change in that section as well. It's the next section of 10_linux.
    Below is my 10_linux file and while I have Karmic showing correctly in GRUB I am having difficulty with getting the recovery mode to show the Karmic title instead of the standard recovery title.

    For me, testing lucid, to get a menu item "lucid 2.6.32-19-generic (recovery mode)"
    change the bold dark red section above to:
    linux_entry "${codename} ${version} (recovery mode)" \
    I think that is what you are looking for. Don't forget to update-grub after saving the change.
