At minimum, that means you could have grub on /dev/sda I have a setting with three bootloaders chained. First Grub2 who boots Gentoo or the Windows XP bootloader. The Windows Bootloader has to option to start Windows XP or a second Grub2 that loads a Xubuntu installed with wubi inside of a 30GB file on the ntfs drive C:. I am more then happy when I get the ok to kill Windows and Xubuntu, because that chain is very creepy ;-) Greetings Sebastian

It is for the usual definition of primary bootloader as the one that is loaded and run by the BIOS. Grub can chainload any bootloader that's visible to BIOS. At minimum, that means you could have grub on /dev/sda (primary bootloader) chainload grub on /dev/sdb (secondary bootloader). I'm uncertain if it means you could chainload a bootloader stored in the first 512 bytes of /dev/sda8, but I suspect so. You're right, you can. Though to get grub2 to install on a partition like /dev/sda8 instead of in the MBR you have to use the --force option or you'll get some incomprehensable error message when you try to do the 'setup' command. -- Grant Edwards grant.b.edwardsYow! !

Last time I installed Ubuntu on a machine that had a different primary OS/bootloader I chose for it to be installed on the Ubuntu partition and there was not problem with it. It was GRUB2 Then I chainloaded it from the primary bootloader. The OS can do the same, but this means that he can either: a) Install Gentoo's GRUB to the MBR and chainload from Gentoo's grub.conf Mint's /dev/sda8 boot loader (assuming that he has installed the Mint bootloader to /dev/sda8 instead of the MBR); or b) Install Gentoo's GRUB in Gentoo's partition, or some other partition (e.g. a boot partition specific to Gentoo) and chainload this from Mint's GRUB2. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
