Error 15 on booting -- SOLVED

[skipperx]

I installed XP first, and then Kunbuntu 7.10 and got it working OK. Then I reinstalled the XP at the same place. I did delete, repartition and format XP partition as it was. Then I lost the dual boot. I fixed it with

Sudo grub
grub>find /boot/grub/stage1
------> (hd0,7)
grub>root (hdO,7)
grub>setup (hd0)
grub>quit
$exit

Then I rebooted and got the dual boot screen as before and choose the ubuntu as before , but I got

Error 15:File not found
Press any key to continue..........

Can someone please help me.

Thank you.

Re: Error 15 on booting

Thanks for the link. I did not touch the menu.lst file. However, I guess I should look at it. I can boot with live CD and can do a few things. However, cannot see that file yet. Could you please explain how I use konqueror as in this

"If so, do so. Open Konqueror (file manager), navigate to the /boot/grub directory (of the correct partition), right-click on menu.lst, select Actions > Edit as Root, and when you finish your editing, File > Save, File > Quit. "

When I did

grub> find /boot/grub/menu.lst

the output was

(hd0,7)

How do I use that info in Konqueror?

Open Konqueror.
In the URL window type: /boot/grub

You will now be in the /boot/grub directory on the current HD. Locate the menu.lst file.
Right-click the file and select Actions | Edit as Root

Re: Error 15 on booting

I am running it on Live CD. When I entered /boot/gub for url, I got the msg
The file or folder file:///boot/grub does not exist.

Do I have to "boot from first HD" on the Live CD boot menu?

Re: Error 15 on booting

I can type C and get
grub>
in the grub screen while booting off the HD. If that helps.

Re: Error 15 on booting

Ahh. Okay, LiveCD.

What HD is Kubuntu installed on (do your remember the sdxy (x=drive number [0=1st, 1=2nd, etc], y=partition [1=1st, 2=2nd, etc])? Assume for the moment that it's installed on the first HD in the 2nd partition (sda2). After you are booted to the Desktop from the LiveCD, open a console and type:

cd /
sudo mkdir tmp/Kubuntu
sudo mount /dev/sda2 tmp/Kubuntu

Note the space between /dev/sda2 and tmp/Kubuntu.

This will mount the partition. You can then navigate to the GRUB menu.lst file in Konqueror (tmp/Kubuntu/boot/grub)

If you don't understand the above, let me know. Bottom line is you need to know on what HD and in what partition you installed Kubuntu's root directory.

Re: Error 15 on booting

I edited the line
root (hd0,5)
in the grub menu during the boot to
root (hd0,7)

and it booted like nothing ever happened. However, it didn't change in the menu.lst because it goes back to (hd0,5). So, I assume I have to edit the real menu.lst file. I am looking at it with Konqueror right now. How do I edit these entries and save it?

Re: Error 15 on booting

Hang on. Sorry. Stupid Q...Let me finish it

[skipperx]

Re: Error 15 on booting

I think I fixed it. I edited these lines in the menu.lst

root.......(hdX,Y)
#groot=(hdX,Y)

The 2nd one seems to be just a comment. But what do I know.

Thanks V much again.

Re: Error 15 on booting -- SOLVED

The test is in the reboot!

Let us know if you in fact solved your problem.

Re: Error 15 on booting -- SOLVED

Yeah, I did.

I am so glad that I didn't reinstall the whole thing in a panic....instead of changing a number from 5 to 7...

I think the partition numbers (designations of some sort) changed when I deleted and repartitioned. I really wanted to only format it and Windows setup was not co-operating. Maybe I should have just booted from the Windows CD and formatted the C drive. That would have left the partitions untouched or so I hope.

You can pretty well tell by now that I am not very good with this programming stuff.
