Boot from 2nd hard drive

I have another HD with Ubuntu on it. Question: How can I add it to my boot menu? Thanks in advance…

#2

Please open a terminal and become su -
Post result of: fdisk -l

Tell us if you can which partition on the HD in question contains Ubuntu root

Here’s what happened. BTW I’m a novice with ‘terminal’.

polluticrus@linux-qs4l:~> su -
Password:
linux-qs4l:~ # fdisk -1
fdisk: invalid option – ‘1’

Usage:
fdisk [options] <disk> change partition table
fdisk [options] -l <disk> list partition table(s)
fdisk -s <partition> give partition size(s) in blocks

Options:
-b <size> sector size (512, 1024, 2048 or 4096)
-c switch off DOS-compatible mode
-h print help
-u <size> give sizes in sectors instead of cylinders
-v print version
-C <number> specify the number of cylinders
-H <number> specify the number of heads
-S <number> specify the number of sectors per track

fdisk -l

That’s a lower case L

Thanks. sdb1 I think. Here’s the copy from terminal. It’s on the 160 gigger…

I’m going to assume you use Gnome, use this command in a terminal

gnomesu gedit /boot/grub/menu.lst

Go to the end of the last boot entry and hit enter a couple of times and paste this in:

#Don't change this comment - YaST2 identifier: Original name: none#
title      Ubuntu 
root       (hd1,0)
kernel     /vmlinuz root=/dev/sdb1 ro quiet splash
initrd     /initrd.img

save

On reboot you should see the entry in the boot menu
hopefully it will work

Yes it worked! Many many thanks for your time, effort and knowledge; you’re a gem.

#8

We try out best.
Happy my advice worked :wink:
