    Re: No grub2 boot menu

    I'm on a business trip and can't experiment with forcing "recordfail" display the menu. G2 is designed to display the menu if there is a problem. We could try to force the recordfail value to indicate an error, in which case the menu will/should always display. On the downside, it would always require an action by the user to boot (pressing ENTER). I'll try it when I return home.

    In the meantime, please post the results of any text at the start of the following (no need to post all the # symbols). This file can store variables for use at the next boot:
    Code:
    cat /boot/grub/grubenv
    GRUB2

    Here we come....there was no text at all...or did I make a mistake?
    cat /boot/grub/grubenv
    # GRUB Environment Block
    ##########...........##
    #root@karibu-desktop:~#
    Anyhow, the good news is that I finally have the grub2 boot menu on my desktop
    My guess with the hardware was not so wrong...
    It seems that the on-board graphic chip is not identified correctly during the boot procedure. The solution was a change in /etc/default/grub:
    before ---> #GRUB_GFXMODE=640x480
    after ----> GRUB_GFXMODE=800x600

    Maybe it's not a very professional fix, but I can live with it!

    Congratulations.

    There normally isn't text in that file - so that's not a problem.

    As far as the resolution goes, if you don't like the resolution you have chosen you can press "c" at the grub menu to get to the command line and then type "vbeinfo" to show what resolutions your computer should display. You could then choose one and put that in the GRUB_GFXMODE and see if your card accepts it.

    Glad this one is solved....

    and THERE it says:

    o The user may force displaying the menu as the computer boots by holding down the SHIFT key.

    No Esc key mentioned. And only for valid single-OS computers.

    On computers on which Grub 2 recognizes multiple OS's
    #The keystatus check for SHIFT key usage is bypassed by the scripts. Holding down the SHIFT key during boot will not display the menu.
    I can conform that it exactly works as described THERE.

    To whom it concerns: Maybe it's worthwhile to overhaul the WIKI !?!?

    The community doc (technically not a wiki) was written for 1.97~beta and I decided not to change it until 1.98 was incorporated and available in the official release of 10.04 Lucid in late April. I make frequent changes to the Grub Basics thread as that's just a post in these forums and is easily changed. Making changes in the community doc is a bit more involved - nevertheless it must be correct. There are several things which still need reconciliation - this apparently is one of them.

    I'll take a look at both. Thanks for pointing this out.

    Update: I have included a statement in the community doc that the SHIFT function is for single-OS computers only.
