GRUB is not configured correctly after installing Kubuntu

9a3eedi · 10-04-2006, 02:05 PM

If anyone of you recalls from my last thread, I was considering on whether to reinstall my corrupted SuSE or to format the partition and install Kubuntu. I decided on the latter, so I downloaded an AMD64 build DVD of Kubuntu, burnt it, booted it up, and attempted to install it on my old linux partition.

Everything seems to have gone well, until I had to reboot it. When I reboot it, I get a bootloader menu which is GRUB. I tried running Kubuntu, but it doesn't mount the partition. I tried running Windows, but it gives me the message that NTLDR is missing (which I know isn't because I never touched it).

Right now I'm on the liveCD of Kubuntu (don't know why.. I think I'll boot Knoppix now), and I'm writing this post in desperation. I don't know what to do and I hope somebody helps me out as soon as possible.

and I do NOT want to format my whole PC .___.

Okay, calm down. This is usually fixable. From your live CD, give us the output of fdisk -l (that's L, not 1). This should print the disk geometry, number of partitions, etc.

Also, if you know which drive contains your kubuntu install, mount it and navigate to /mnt/kubuntu/boot/grub (NOT just /boot/grub, because that would be the LiveCD's /boot directory). Post the contents of the menu.lst file.

Or if you're good at following directions without any further assistance from us, follow B5 of this post. Just change /dev/hda4 and /dev/hda to the correct partition/drive where you installed Kubuntu.

Just for completeness, let's also see the (hard-disk) /boot/grub/device.map

there you go

Code:

(hd0)	/dev/hda
(hd1)	/dev/hdb
(hd2)	/dev/sda
(hd3)	/dev/sdf

For the Windoze issue, I'd be looking to ensure that ntldr was in fact on /dev/sda1. What about /dev/hdb1 maybe ???. At the grub menu, select the 'doze entry, and hit the "e" key. Change all the hd2 to hd1, (hit <enter> for each separate line), then enter "boot", and see what happens.

What does this mean - exactly ???.
Error 17, or something else ???.

I'm pretty sure that ntldr is in fact in sda1 (which is my windows partition), as seen in this snapshot

No it just gives me exactly the same error message:

Cannot Mount Partition

but I can't remember whether there was an error number with it or not.

bbump

i desperately need to boot into my windows partition

syg00 · 10-06-2006, 05:43 PM

Well, why didn't you say so earlier ???.
Check M$ofts site - they have pages with this info.

The standard answer to this is to boot the Windows CD, hit "r" when it tells you, and from Recovery Console run fixmbr.
This will replace the bootloader (grub in your case) with the M$oft one. You may also find you need to run fixboot (from recovery console) to get around the "ntldr not found".

umm I already said so.

and while this solution would allow me to boot windows, it wouldn't allow me to boot my freshly installed kubuntu, now would it...

It seems like it should be working. Maybe try reordering some of the terms like this

Code:

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title		Microsoft Windows XP Professional
rootnoverify		(hd2,0)
map		(hd2) (hd0)
map		(hd0) (hd2)

I attempted doing so, but it still doesn't work. NTLDR is still.. "missing" when it's not, as I've shown you a couple of posts ago.

I also tried booting kubuntu one more time, and it gives me the same error message, but I would like to add that it was error number 17. The more information the better I suppose. Plus, the messages state that the file system type is unknown, so maybe this also has some relevance.

bump. I need to solve my problem ASAP
