 Posted: Fri Apr 15, 2005 1:54 am Post subject: Grub problems with USB harddisk |
 |
|
Good evening all,
I have Windows XP and Gentoo Linux installed on my Clevo d900t notebook without a problem, except one:
After installing Windows XP and later Gentoo, grub worked fine until I connect my USB harddisk to the notebook. When I reboot grub stops giving a "error 17" code. I believe that means it cannot find the boot partition?
Grub will work again when I switch off the USB drive, but it is quite annoying having to do that everytime I reboot the computer (especially during installation of Windows and Gentoo this has to be done quite some times).
How can I prevent grub failing while having my USB harddisk connected during boot?
To give you some more details:
Windows is installed on sda1
/boot is on sdb1
/ is on sdb3
The USB drive is on sdd1 after booting Gentoo (strangely it is on sdc1 when booting from Gentoo installation CD).
Here is my grub.conf:
| Code: | default 0
timeout 20
splashimage=(hd1,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.11-r6
root (hd1,0)
kernel /kernel-2.6.11-gentoo-r6 root=/dev/sdb3
title=Windows XP Professional
rootnoverify (hd0,0)

Barabas2005,
It sounds like your drives are getting reordered. Add
| Code: | title=Gentoo Linux 2.6.11-r6 (With USB Connected)
root (hd2,0)
kernel /kernel-2.6.11-gentoo-r6 root=/dev/sdc3 |
to your grub.conf and see if that boots.

The problem is that Grub doesn't even get that far that it shows me the list with OS's to boot. When booting it doesn' give the list, but it shows the following right away:
| Code: | Grub loading stage 1.5.
Grub loading, please wait
Error17 |
So it looks like it is booting grub, but grub can't find it's files anymore. It may be - like you said - that the drives get mixed, but I have no way to see which drive is going where. When I boot from the Gentoo CD, the drives are shown in the same order as it is after booting from my notebook (I have to shut -down my external drive until the grub menu is shown).
Do I need to do something with the grub-install command to get things right?
Thanks,
Barabas |

Barabas2005,
You need to edit /boot/grub/device.map
Your USB drive is probably not listed. This is how grub finds it way around.
