Grub O/S error

[Charles2008]

Hi,

I'm a newbie and attemped to install Ubuntu 7.1 on my new second hard drive. As soon as the install finished, I got an o/s error when windows xp pro sp2 started to boot up. I tried installing with the alternate text installer and got the same result. I can load ubuntu with my live cd, but I don't know how to fix the installer. Please advise.


Thanks in advance,


Charles

You should be able to get Windows or Linux to boot using the SuperGrub CD - this may be worth a try.

Does any OS boot eg Linux ? does the install program run to completion and attempt to reboot or are you having to force a reboot ?

I get an error that says "error loading o/s"

I have to press the reset button on the computer to start the system again.

As soon as the error appears everything stops booting. It does not boot to completion. I can only get the system to boot using the Windows install CD or the Ubuntu CD.

Have a look at the super grub disc. Download the iso and burn to a cd. Reboot from the cd. It is an easy way to restore grub

Its GRUB/BIOS compatibility issue.

* First of all, unplug second HD and boot up from first HD having Windows OS. If Windows OS doesn't boot up, boot up from SuperGRUB CD and select 'Fix Windows Boot Loader'. Windows OS will boot up on reboot.

* Unplug Windows HD and plug-in second disk as Primary. Install Ubuntu. Installation will work fine and Ubuntu will boot up properly.

* Plug-in Windows HD as Secondary. Ubuntu will boot up by default. Open Terminal and execute this

sudo fdisk -l

==: -l, Its small L.

Post output here. We'll post code for setting up Dual Boot. You have edit only one file for that.

Followed above instructions and here is the output.

thanks in advance for future help,

Press Alt+F2 and type this

gksu gedit /boot/grub/menu.lst

It will open menu.lst file in Gedit.
Add this code at the end of file

title Windows XP
rootnoverify (hd1,0)
map (hd1) (hd0)
map (hd0) (hd1)
chainloader +1

Save file and reboot machine. Select Windows XP title in GRUB Menu.
