    Hi, can someone please explain this "Advanced" option? Does it mean Grub can be placed where I want it and is there a possible advantage to this? Thanks!

    Hi wat0114,

    hd0 refers to an IDE Drive
    ../sda = if you want to install Grub to the MBR of the 1st HD
    ../sda1 = if you want to install Grub to a partition boot sector. In this case
    the 1st partition of the 1st HD
    ../sda6 = would be 1st HD 6th partition. (Within an extended partition ?)
    Hopefully someone with Vbox experience will pop along for a nice
    explanation. :D

    Regards.

    Hello,

    Partitions 1-4 primary, one can be extended.
    Partitions 5 up, logical.

    Grub can be installed to the root of any device, be it physical disk or partition, hence you can place it anywhere you want. Of course, if you want to be able to boot directly from bios, you need some kind of bootloader in the root of the disk itself.

    So you can have, for that matter, dos bootloader or something in there, pointing to grub installed somewhere else. If you're dual booting, this makes the difference. If it's a single boot, this is meaningless.

    P.S. Nothing to do with BV by the way ...

    Mrk

    Sometimes I arrange my system with a 100 MB primary partition that is mounted as /boot. And then I install Grub in the boot record of that partition as opposed to MBR.
    The advantage is that you avoid that Grub is overwritten when you reinstall MS Windows, which always recreates the MBR and activates the primary Windows system partition.
    With a simple command you make the /boot partition active and then linux is bootable again.

    This approach also permits other software to overwrite the MBR, for example another boot manager, or some Windows maintenance software that needs to boot before Windows.

    I don't think that installing Grub in a record of a logical partition will work.

    Thanks to all for the help! I guess in the VBox install I won't worry about it. I'd always gone with the default location in the past when I installed Linux dual-boot with Windows, so Grub would take over from the Windows bootloader. I realize things are a little more complicated with Vista/Win 7, but I kind of get the concept. Maybe next time I will try something different. At least if I mess up my iimage restore recivery disk can bale me out ;)
