View Full Version : [ubuntu] [SOLVED] Need to set up a dualHD/dualboot

September 21st, 2008, 10:43 PM
Just reinstalled Ubu.8 after a major crash.
I have a Win.XP hard drive and a Ubu hard drive.
I can unplug the Ubu. drive and boot windows but Grub doesn't give me the option to boot Win. when both drives are connected.
I have mounted the Win drive and can access it's contents.
How do I get Grub to offer WinXP as a boot option?

Look at this thread: http://ubuntuforums.org/showthread.php?t=920862&highlight=super+grub

Download Super Grub (you will have to search), burn to disk and boot system via the disk. It can fix things for you. This is a very quick reply so someone else may need to give further details. I have used this utility on many occasions and it will fix things up.

There's a grub howto here (https://help.ubuntu.com/community/GrubHowto) from the Ubuntu wiki. You probably just need to reinstall grub to get it to pick up the XP install-there are additional links at the page I linked here.

Might be a little late but here is what I did a few years ago to eliminate hard drive issues. I use a hard drive rack. This photo shows the hd partially out with the keys for locking, plus three more hard drives. The cover is off of one rack.
I have two drives with Ubuntu 8.04 on each. The one marked B is in case the one marked A ever fails. My personal files are backed up on a Firewire external hard drive. It would take me a couple minutes to be back online if a hard drive ever fails.
One hd is Linspire 5.1.427. The fourth hd is Ubuntu 8.04.1 for trying.
One hd, one OS.
I gave away a 98 hd with a PC to my brother.
I installed the new hard drives without formating or partitioning right out of the box. After nearly five years I have never seen any reason to partition a hard drive.
I want to run applications, mot Operating Systems. I do not mess with the OS.
Your mileage may vary.

I am booting from usb flash drive and have this at the end of my /boot/grub/menu.lst:

# This is a divider, added to separate the menu items below from the Debian
# ones.
title Other operating systems:

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title Microsoft Windows 2000 Professional
root (hd0,0)
chainloader +1

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sdb1
title Microsoft Windows XP Professional
root (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

It lets me choose between hard disks at grub.

I think the last entry should do you.
