hi, i was looking for a possibility to boot grub 2 without needing a filesystem with grub files somewhere on the disk. i know i can make such an image with grub-mkrescue, but it generates an iso which, as far as i know, is not bootable directly from disk. even when i have created a disk bootable image with grub-mkimage, how do i get the pc bios to boot this from a gpt formatted disk? is there some standard mbr bootcode i can install that just locates the bios boot partition in gpt and chain loads it, so i could just write the grub image to this partition?
it may look a bit strange why to not just put the files on some filesystem on disk which you will have anyway if you are going to install some operating system. but my reason for this is that the installation is automated and updating is a lot easier if i just have to write a new image, instead of updating files on a filesystem, which would not be done automatically by a package manager. also i had a lot of trouble with grub-install depending on what environment i executed it in. writing some mbr bootcode and the grub image to the boot partition looks a lot easier to me. thanks, anselm _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
