    I have read somewhere that grub 2 which will be shipped with Ubuntu Karmic (9.10) does not have the option to install to / (only to mbr). Then again I have also seen somewhere that it does indeed have this option. Which version is correct ?
    Assuming that there is the option to install to the root partition, would it be OK to use the 'legacy' grub installed in mbr to chainload Karmic ?
    I am currently chainloading Jaunty (64 bit) from my Hardy (32 bit) and when Karmic K. is released might want to replace Jaunty with it.
    I am sure many here will already have tried Karmic K. alphas - does it live up to expectations ?

    Regards

    It's all changed - :argh: - means re-learning grub :thumbd:
    Here some links:-
    https://wiki.ubuntu.com/Grub2#Dual-booting
    http://grub.enbug.org/CommandList
    .. and one from Arch (but /boot/grub/grub.cfg is not meant to be edited).
    http://wiki.archlinux.org/index.php/GRUB2

    How to boot Grub 2 from Grub legacy (my main concern)

    Seems one needs the --force command to get grub2 installed to the boot sector. Maybe this
    will be ironed out in the Karmic final release.

    sudo grub-setup --force /dev/sdb2

    Also numbering has changed :
    (hd1,1) is for second hard drive, second partition in Grub legacy in Jaunty for your chainloader command.
    (hd1,2) for second hard drive, second partition in Grub2 in Karmic.
