There seems to be some problem with the grub entry in the MBR, even thought it obviously wrote a boot menu, so the installer thought it did the job OK.

So, you can boot and run the Live CD?

Is there another OS installed on that computer? Are there any "special" setups with the other OS? Was there a previous OS installed on the hard drive?

You might need to make a GParted Live CD and set the "boot" flag on the partition where you have Kubuntu installed, if that is also the partition where you installed grub. Get the GParted Live CD ISO from here:

http://sourceforge.net/project/showf...kage_id=271779

I think I'd use GParted to re-format the partition, set the boot flag, and then install Kubuntu again (with my fingers crossed and a prayer to the little monkey-god).

Re: kubuntu fails to load after grub menu

I'll take a guess that GRUB is set up OK, but the installation of your II is bad (and/or the menu.lst entries are not correct).
Seems to have trouble finding your root device. Doesn't recognize the UUID.
In the II menu.lst for Kubuntu (the entry that you selected from the boot menu when this happens), there's a kernel line and an initrd line, each containing
root=UUID=etcetc
Did you check that UUID (where the Kubuntu root files are located)?
UUIDs, listing:
From Live CD and HD: ls /dev/disk/by-uuid/ -alh
From HD: blkid
If it is correct, then check to see that you have kernel (vmlinuz) and initrd (initrd.img) files in your
/boot
directory. You need the “vmlinuz...-generic” files and not just the backup “...-generic.bak” files (and same for initrd.img files: not just the “initrd.img...-generic.bak” backup files).
And maybe you could copy your menu.lst here (just the important parts containing the “title” sections).
I don't have II yet, but these guys do and they could check it against theirs.

Re: kubuntu fails to load after grub menu

I am experiencing the same problem? To be exact, the KDE 4 graphical login screen does not load, I only get the user login prompt in text mode.

[edit] Here i what happened, as far as I can tell:

I was running Kubuntu Hardy Heron. It had both KDE 3 and 4. Then at about Saturday Oct 18, 9am American Eastern time, I decided to upgrade from Hardy to Intrepid Beta via internet connection (as opposed to live CD). I followed the instructions on https://help.ubuntu.com/community/In...grades/Kubuntu

The download and install of Intrepid packages succeeded, as far as I can tell. After installation and cleaning up of obsolete packages, I got the message saying Kubuntu has to reboot to upgrade to complete.

Reboot my notebook PC, then I get to the GRUB menu with listings of kernel versions and WinXP Home. I select the latest kernel 2.6.27, then get the initial Kubuntu splash screen, and in the meantime I presume various services are being loaded.

But next I get a text screen with user login prompt. Not the graphical KDE 4 login.

I checked, and the vmlinuz and initrd.img files do exist in /boot. This could not be a problem with the kernel, could it? Because if it's a kernel problem, how would I have even gotten to the login prompt?

Could it be a problem with KDE 4's desktop not loading? Because if I select recovery mode from GRUB, I see a lot of messages telling me what services are being loaded, then at the end I get a message saying "kdm-kde4 is not the default display manager", then the login prompt.

Re: kubuntu fails to load after grub menu

Sure doesn't sound like a GRUB problem.
As for the rest (the mechanics of the log-in screen), others here may have some ideas and tricks.

**tkteo** · Oct 18, 2008, 09:51 PM

Re: kubuntu fails to load after grub menu

Okay, I still do not know what the problem is exactly, but now I get the KDM login screen and managed to login to get to my KDE 4.1 desktop screen.

Nor do I know how I resolved the matter exactly. But this is what I did.

1. Booted into recovery mode.

2. Deleted my current Intrepid version of /etc/X11/xorg.conf

3. Copied contents of my previous Hardy version of xorg.conf, which had been backed up and renamed as xorg.conf.dist-upgrade

4. Ran apt-get to remove and then (re)install xserver-xorg-video-ati, xserver-xorg-video-radeon, and xorg-driver-fglrx and fglrx-control (cos my notebook PC has the Radeon Xpress 200M).

5. apt-get informs me that the fglrx-control is not available, but is replaced by fglrx-amdcccle

6. So I also installed this fglrx-amdcccle along with reinstalling the rest.

7. Rebooted.

8. GRUB, then select latest kernel, then yes, I got the KDM 4 login screen.

So it seems to have something to do with the ati or fglrx drivers for the ATI video chip?

Re: kubuntu fails to load after grub menu

But now I cannot reboot the computer properly. The system hangs after I select "restart". I get funny lines on the screen, and it just hangs there

Out of pure frustration, I hit Ctrl-At-Del, and I managed to get to the reboot splash screen...

What's going on?

Where is this adventure with Intrepid headed to?

Re: kubuntu fails to load after grub menu

Ok! thank you for your responses

I don't think it is anything to do with grub through I'm not a linux guru. This is because I have windows installed and I can get into windows with some adjustments in grub. The installation wasn't smooth. After installation grub was pointing to the wrong drive e.g. [root (hd1,6) instead of (hd0,0)]. So I altered menu.lst file to correct the error. But now I have this problem.

I have 3 os installed. 2 windows and kubuntu.
hd0,0 = windows
hd0,? = windows
hd0,6 = kubuntu

Qqmike I have check the uuid in busybox after it fail to boot and it is there. I have also check with the liveCD uuid number is still the same for the boot partition.

kernel and initrd.img is there

'ls /dev/disk/by-uuid/ -alh' on the liveCD

Re: kubuntu fails to load after grub menu

sde7 = your Kubuntu II -- the partition that is not booting, and this is (hd0,6), right?
Have you set your BIOS to boot from that drive (the drive that is called sde)?
The drive hd0 is always the first drive set to boot in BIOS setup, (Usually, (hd0,6) would correspond to sda7, not to sde7.)

Back to the error message:
Starting up ...
Loading, Please Wait...
Gave up waiting for root device. Common problem
- Boot args (cat /prog/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for right device)
- Missing module (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/3328a24e-ca23-4ce9-88cb-1c90e1588e5b does not exist. Dropping to shell!

I'm not an expert here, but that sure seems to suggest that something is missing (a partition, or a module). The stuff contained within parentheses are tips of what you might try at the BusyBox prompt to help diagnoses the problem. Of course, that all presupposes that we are able to decipher what the heck is returned when you do those commands (cat, ls).

=> a bad installation? (assuming that it is not something simple, like the sda and sde stuff I mentioned at the start of this post)

Might be helpful/informative to see what your /etc/fstab file contains.

Yes the bios boot that drive. When I boot from that drive sde7 is actually sda7, from the liveCD it is sde7. And yes the partition not booting up is (hd0,6 = sda7)

This is the second time I install kubuntu and it came up with the same error. Have attach the results for the command 'cat /proc/modules; ls /dev'. I think you might be right that something might be mission. What I'm going to do is download the iso and burn it again and try to install it. There may have been an error on the disc.

Re: kubuntu fails to load after grub menu

Hello
same problem as described by chylee

What I'm going to do is download the iso and burn it again and try to install it. There may have been an error on the disc.

I try with 2 differents disk (and check iso md5 sum) and ... always the same situation !

Re: kubuntu fails to load after grub menu

I'm having a similar problem on my laptop. Grub would load fine and then I would get stuck on the Kubuntu logo screen where the blue bar was loading across the screen. I would stop about 1/10th of the way across. Used to be I could power off and power on and the next start would load fine. Now I can't get past the Kubuntu logo screen. I put my other hard drive in, the one with Kubuntu 8.04, so I could even type this message.

What is recovery mode? Is that the F4 I've read about in other posts?

Assuming you 'see' your Grub boot menu, it's the second item in the list.

Re: kubuntu fails to load after grub menu

Like Fred Installing again hasn't solved them. The grub menu.lst file was configured wrong. The root command was point to the wrong partition. It was pointing to hd2,6 rather than hd0,6. I corrected this but now I'm back to the same problem
