This is great info. I know of one case a long time ago, maybe 2001 or 2002, where I used an older drive and got burned by a preexisting copy of grub in the MBR conflicting with the version I had installed into a specific partition. I kept thinking grub was working but doing the wrong thing. I suspect that had I run some commands like the ones were talking about here I would have found the problem. As it turned out I didn't and went the direction of completely repartitioning the drive. What a waste! Cheers, Mark -- gentoo-user@lists.gentoo.org mailing list
