I got bitten by this again in the Gutsy RC on my new PC. I posted my experiences here http://ubuntuforums.org/showthread.php?p=3518911#post3518911.
In brief: My BIOS sees my drives as: HDD1 - 80 GB - Windows HDD2 - 80 GB - Linux HDD3 - 250 GB - Media Linux sees them as: /dev/sda - 80 GB - Windows /dev/sdb - 250 GB - Media /dev/sdc - 80 GB - Linux So it generated device.map assuming that order was correct, i.e.: (hd0) /dev/sda (hd1) /dev/sdb (hd2) /dev/sdc but it should have been: (hd0) /dev/sda (hd1) /dev/sdc (hd2) /dev/sdb I see this as a pretty big issue, because it rendered my system unbootable (both Ubuntu and my existing Windows installation). -- grub guessed BIOS disk order incorrectly https://bugs.launchpad.net/bugs/8497 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
