I have Mint installed on a second hard drive. The command
chainloader (hd1,0)+1 worked fine to get to the Mint GRUB on my older Kanotix install, but now with Thorhammer this does not work. Grub-install found the Mint kernels and set them up, but they also fail. For some reason the new Grub installation cannot find the second drive.
I have several other partitions on my first drive that all work great, for example
chainloader (hd0,5)+1
works fine. The only one that does not work is the one pointing to the second drive. Any ideas? |

| Check BIOS if the drive is mentioned there. |

You can see in the menu.lst that I have commented out some of the options that did not work. I can mount the second drive with no problem, so I assume it is not a bios issue. This worked fine before I upgraded to Thorhammer, so it seems to have something to do with grub on this new version. |

| You can not use map command for Linux. As soon as the kernel loads it must use the saved root=... value. map is only for Win/Dos and other easy systems which have no root Option. |

| I added the mapping commands in desperation after it would not work. Can you recommend a chainloader command that will get me to the second hard drive? This worked fine with no problems before I upgraded. |

That's the UUID for sda10, no? Not the UUID for sdb1, which is what you want?

It may not be in keeping with this newfangled UUID thing, but you still should also be able to use something like
title Mint, kernel 2.6.20-15-generic
root (hd1,0)
kernel /boot/vmlinuz-2.6.20-15-generic root=/dev/sdb1 ro quiet splash
initrd /boot/initrd.img-2.6.20-15-generic
to start it. |

I can try that, but I am really trying to get chainloader to work so that I can address grub installed on the second disk (for Mint). I have tried:
root (hd1,0)
chainloader +1
and
chainloader (hd1,0)+1
Neither worked. I get a Grub error #13. |

| Maybe the chainloader command fails because there's no bootloader installed in partition #1 on hd1. If grub is located in the MBR of hd1, the chainloader command pointing to partition #1 won't find it. |

Yes! That was it. Mint Grub was on HD1 instead of HD0,1. It was time for Mint to go anyway, so now the second drive has Vector Linux with LILO installed on the partition, and chainloader (hd1,0)+1 gets me there.
Looks like Kanotix and grub were fine all along... imagine that...
Thanks for your help! |
