I am having a problem with dual booting Ubuntu 8.04 and Windows XP. Now before i go on i would like to say i am brand new to Linux so I'm sorry ahead of time if i sound dumb.

I have Ubuntu installed on it's own separate partition from Windows. At first when i installed everything worked perfectly. I could boot both Ubuntu and windows anytime i wanted with no problems. Now whenever i go to boot Windows XP it gives me Grub error 22: no such partition. I think this started happening after I updated Ubuntu from 16 to 17, but I'm not sure. When i go to edit the Windows XP at the screen where you pick which partition you want, it says that windows is root(hd0,0). I have no idea what this means but help would be greatly appreciated.

Thanks

After Grub starts hit the 'c' key

# rootnoverify (hd0,0)
# chainloader +1
# boot

If you still get an error ... you must have done something.

In (hd0,0),
hd0 is your 1st hard disk and
0 is the 1st partition.

Alright i did that and it now says Starting up... but then it just stays there and never boots anything.

If you boot into ubuntu,

# sudo grub-install /dev/sda

(or is it /dev/hda ... your first hard disk)


Get super grub disk too

Searching for GRUB installation directory ... found: /boot/grub
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0) /dev/sda

Is what i get after i do the sudo grub-install /dev/sda.

Also i believe I'm going to have to go buy some more CD-Rs before i can get super grub disk. Will this be a problem?

EDIT: When i do /dev/hda it says Not found or not a block device.

If you are able to boot into ubuntu run the command: sudo fdisk -l (that's a lower case letter L), you will be asked for your user password, enter that and post the result of the command. It would also be useful to post the contents of the menu.lst file which is in the /boot/grub directory. You won't need to post all the lines commented out (#) at the beginning of this file.

Can you give us your 'fdisk -l from ubuntu terminal. This will give us your hd and partition layout.

Here is fdisk-l

By the way thank you very much I appreciate this greatly

Boot your ubuntu disk and from terminal

sudo grub

and at the grub prompt

root (hd0,4)
setup (hd0)

This should repair your upgrade.
