[gentoo-user] Shouldn't grub setup overwrite lilo in MBR
I thought I'd try once more to get grub working in my prefered resolution. I've been able to get what I want with lilo right along. I just assumed grub would overwrite lilo code in the MBR but I'm finding it does not. It cripples lilo boot so that it doesn't work but I still get the dreaded ..`Li..' hang on boot. Just for the record, shouldn't grub setup (hd0,0) overwrite any other code in MBR? If it does not what does it mean? Grub would show a failure if it did not find /boot/grub and the files under there when setup is run so it seems to succeed. I'm sure lilo is aimed at hda as well and can see it in lilo.conf, further if it were running from another parition it wouldn't get crippled from running grub against hda... right? So I guess I need to zero out the mbr somehow. I faintly remember some dd syntax involving 0 (zero) but can't find it now to refresh my memory. dd if=/?? of=?? -b 512? with the right stuff in there can clean the mbr right? -- gentoo-user@gentoo.org mailing list

No, it says to install the boot code into the first partition of the disk, not the mbr. This would be useful if you use a microsoft mbr (fdisk /mbr, or fixboot from a recovery console), which looks for the 'active' partition to determine which OS to load.
