    Default boot

    SOLVED

    ]Once again I have outsmarted myself by re-installing Ubuntu 9.04. The grub loader insists upon making the new Ubuntu the default to load. I wish to have the Windows boot loader be the default and have edited menu.1st to no avail.

    Here is a copy of menu.1st. What's wrong please?

    # menu.lst - See: grub(8), info grub, update-grub(8)
    # grub-install(8), grub-floppy(8),
    # grub-md5-crypt, /usr/share/doc/grub
    # and /usr/share/doc/grub-doc/.

    ## default 4
    # Set the default entry to the entry number NUM. Numbering starts from 0, and
    # the entry number 0 is the default if the command is not used.
    #
    # You can specify 'saved' instead of a number. In this case, the default entry
    # is the entry saved with the command 'savedefault'.
    # WARNING: If you are using dmraid do not use 'savedefault' or your
    # array will desync and will not let you boot your system.
    default 4

    ## timeout sec
    # Set a timeout, in SEC seconds, before automatically booting the default entry
    # (normally the first entry defined).
    timeout 04

    ## hiddenmenu
    # Hides the menu by default (press ESC to see the menu)
    #hiddenmenu

    # Pretty colours
    #color cyan/blue white/blue

    ## password ['--md5'] passwd
    # If used in the first section of a menu file, disable all interactive editing
    # control (menu entry editor and command-line) and entries protected by the
    # command 'lock'
    # e.g. password topsecret
    # password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
    # password topsecret

    Re: Default boot

    You can find the answer on how to fix your problem is here, a thread I just responded to yesterday. You can follow either the text editor solution or the GUI one if you prefer.

    Your problem if you want to text edit it, is that this:
    Code:
    title Ubuntu 9.04, kernel 2.6.28-11-generic
    uuid 1161a518-f455-4d3a-9f94-b068f2cda8cb
    kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=1161a518-f455-4d3a-9f94-b068f2cda8cb ro quiet splash
    initrd /boot/initrd.img-2.6.28-11-generic
    quiet
    Is the first entry, instead of the windows entry in red as you highlighted. Move it up to first spot and problem solved. You can also just use the GUI if your not so enclined to manual editting.

    And, you should update that machine, if it's jaunty your kernel is old.... we are at least at 13, I just hit 14.

    Re: Default boot

    Thank you for your informed and quick reply. I decided to try StartUp Manager and found it easy to use and effective. Thus I made no further attempt at editing.

    StartUp Manager also has an option to create a rescue boot floppy for GRUB. I would suppose that one could just as easily create a bootable CD.

    Have also run the updates and now have kernel 15.
