Ubuntu :: Grub After Updates On Karmic?

Apr 24, 2010

I'm having a problem with Wubi on my netbook, and while I could fix it easily (though probably only temporarily) by reinstalling, I've been using it since January and many of the files are files I cannot afford to lose. I'm dual booting with Windows XP, but when I choose Ubuntu 9.10 from the menu at startup, it takes me straight to Grub with the following message:

Quote:
GNU GRUB version 1.97~beta4 [minimal BASH - like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device/file completions.] sh:grub>

I've had this problem once before, but I was able to fix it with the wubildr patch. Both instances of this problem have occurred after updates, though it hasn't happened after every update, just the two so far.I've also tried several of the command-line suggestions that have fixed this problem for other users, but I've been getting "unknown filesystem" when I attempt them. If anyone has any idea how to fix this without losing the files I have on my current install,

Ubuntu :: No Notification Of Updates In Karmic?

Feb 28, 2010

I've just realised that I've never been notified of updates. I've been checking manually. My parents came back from a three week holiday with their laptop and even they didn't get an alert, it seems. I know this was an issue on kubuntu. Does anyone know about this?

Ubuntu Installation :: Grub - Setup: Warning: Attempting To Install GRUB To A Partition Instead Of The MBR - Install - Lvm - Luks - Raid - Karmic Server

Mar 27, 2010

I'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]

If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.

Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'

Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.

Ubuntu :: Fixing GRUB/MBR From 9.10 Karmic Live Cd?

Ubuntu Installation :: Use Old Grub And Ext3 With Karmic 64bit?

Jan 1, 2010

I have received an Lenovo T400 as a gift and am going to get rid of the Vista Business OS on it! It is a resource hog and sometimes has trouble hooking up to our router. I was curious yesterday on how much RAM was being used on idle and it was between 900mb and 1gb! I'm downloading Karmic 64-bit and would like to use the old GRUB instead of the beta Grub2. At least with the legacy grub I could edit it easier than the beta one. I am also wondering if Karmic would run fine using ext3 instead of ext4?

Ubuntu Installation :: Karmic Grub Updated And Destroyed Itself

Jul 26, 2010

I'm a GRUB novice, unfortunately. My system is a 7-year old Dell tower. Two hard drives, each sliced up into a bunch of ~30 GB partitions. I dual-boot WinXP and Ubuntu Karmic Koala 9.10. I think I have GRUB2, but don't know how to check without being able to boot. This problem arose during a standard upgrade when I didn't pay attention and GRUB updated and apparently destroyed itself. Now when I boot my system, I get the following message:

Code:
Booting from local disk...
GRUB loading.
error: no such disk
grub rescue>

Almost every fix I found in my searching involved:
Code:
grub> find /boot/grub/stage1
but none of the solutions said what to do if that file wasn't found.

When I boot from my Ubuntu install DVD, I can mount my various partitions and browse their filesystems, so it appears that my data is all still intact, I just can't get to it. What should I try next?

Ubuntu Installation :: Grub Failing Completely On New Karmic Install?

Feb 19, 2010

I just installed Karmic Koala on one of my hard harddrive. The other disk has Windows XP. Previously I had a working dual-boot setup, but after problems with Ubuntu I reinstalled it. On booting, I get the following:

Code:
Grub Loading stage1.5
Grub loading, please wait...
Error 2

There is no Grub menu which might allow me to drop to a Grub prompt and evaluate. This occurs whether I boot with the Ubuntu harddrive or re-set the BIOS to boot with the Windows harddrive. If I boot with a LiveCD, I see that both my Ubuntu and Windows harddrives exist and are readable; the Ubuntu was indeed wiped clean and reinstalled; the issue is with the boot process. How can I set this up to boot?

General :: RAID And Grub 2 On Ubuntu Karmic Koala (installation)

Feb 11, 2010

I've been trying to get Grub 2 to work on a desktop system I'm trying to install Karmic Koala on. It's currently got two similar hard drives, which I've partitioned into a small /boot partition and the rest as a large general partition. Both are fd (linux software RAID) types. I boot from the Ubuntu live CD then create the RAID arrays as RAID 1 (requires installing mdadm to work). Then I start the arrays and begin the install.

I select manual partitioning and create the first RAID array (/dev/md0) as an ext4 /boot. The second array (/dev/md1) requires a new partition table. I then partition it as 20G for /, 2G for swap and the rest as /home, giving me /dev/md1p1, /dev/md1p2 and /dev/md1p3. When the install finishes, I mount the various partitions in /mnt (for /dev/md1p1) and below, including binding /dev and /proc. Then I chroot and install mdadm in the new system. I update grub, re-install it on /dev/sda & /dev/sdb then update the initramfs.

A quick reboot and things go wrong... Grub boots me into a recovery console. Apparently it can't see the partitions in the second RAID array. how to get Grub 2 and/or mdadm to work in this situation? I know that apart from the RAID, the above process worked to allow me to set up a Grub 2 boot on an antique laptop with an incomplete install.

Ubuntu :: Updates Screws Up Grub?

Jun 5, 2010

Both my netbook and this machine needs an update (according to the update manager) Well 2 days ago, I let it update the netbook. Bad mistake. Long story short; it installed a new kernel, and monkeyed with GRUB (v1.5) and it wouldn't boot. It's that new grub thing, with the long cryptic numbers/letters string, instead of the more normal hd0, hd1 thing. I had no clue on how to restore it.

How can I back up GRUB next time, let it update, then restore grub back the way it's suppose to work? I tried backing up the menu.lst file, but that didn't work. I backed up, and restored it, and the netbook still wouldn't boot. Got the very same error message. I had to do a partimage to bring back the old image of it. Also Grub-install will not work at all, from systemrescueCD.

Is there some sort of up-to-date tutorial on Grub? I've had more problems with Grub than anything dealing with linux. Especially since anything happens to it, your virtually screwed.

Ubuntu :: Updates Killed GRUB?

Aug 9, 2010

I've been a Windows users since waaaay back when (ahh...Windows for Workgroups 3.1). I've tried Linux in the past (Mandrake many years ago), but didn't feel it was quite ready to be a Windows substitute for me.A couple of weeks ago, I downloaded the latest version of Ubuntu (10.04) and installed it in a dual boot setup with Windows XPSP3. All seemed to be running well, until it came time to install updates in the Update Manager. First an update for GRUB, which promptly killed GRUB and left me with "Minimal BASH-like line editing is supported" message and a GRUB prompt. After booting up the Windows XP install CD, I was able to rewrite the MBR and get back into Windows.

I deleted the Ubuntu installation and reinstalled it, making sure I didn't allow it to update GRUB after finishing up. The other updates listed installed fine and I was able to dual boot with ease.Another round of updates were listed yesterday when I booted up in Ubuntu, I made sure not to include the GRUB update, downloaded and installed them, rebooted and was faced with "Minimal BASH-like line editing is supported" again. Argh. Once again I had to pull out the Windows CD and run FIXMBR to resolve the boot problem.I'll admit to being tempted to just go back to Windows completely (while not perfect, atleast I can get it to boot after updates 99.9% of the time) and forget the idea of running Linux if I'm going to be faced with having to reinstall the OS everytime because something killed the boot loader.

Ubuntu :: Can't Get Newest Real Time Kernel To Show Up In Grub 2 (Karmic)?

Apr 26, 2010

I want to try out the realtime kernel to get my audio latency down. I have installed the realtime kernel packages according to the Ubuntu Studio preparation documentation here - I have also run sudo update-grubHowever, when I boot up, the realtime kernel option does not show up in grub2. The current kernel I am using is 2.6.31-17, but the only options in grub for it are -386 and -generic.

There is a previous entry of 2.6.31-9-rt which I had attempted to use previously (sometime last year) but if I select it, it doesn't even boot at all.I checked my /boot directory and there is no vmlinuz-2.6.31-17-rt file .... Which I am assuming is why it doesn't show up or add when I run update-grub ... But I am currently at a loss for how to actually get the 2.6.31-17 realtime kernel file and add it to grub2.

Ubuntu :: Kernel Updates - No Auto Boot From Grub ?

Mar 27, 2010

I'm remote from my system and so have to wait 2-3 days before I can get access directly, but I've noticed that when the kernel updates automatically (or forced by me), the next reboot stops at the grub page awaiting confirmation of the kernel I want to boot. grub.conf doesnt seem significantly different from that of fedora (my previos distro for this machine) and even has the default lines and times spec'd, so I can't see what's holding it up. Any ideas how I can prevent this so I can have my system auto-updating the kernel AND safe to reboot remotely?

Ubuntu :: Fails To Reboot After Updates Gets Stuck In Grub?

Mar 9, 2010

Just installed Ubuntu a month ago (installed within windows), and for the 2nd time it has gotten stuck in grub upon restart after doing an automatic update. Last time, I reinstalled from the CD, but I can't do that every time. Learning how to start up from grub would probably be worth learning so I don't have to use the CD. But fixing the problem is most important. It makes me wonder if it was a mistake to install Ubuntu from within Windows (does this mean I have "wubu"?). I did find a webpage on booting Ubuntu from grub, but I could not get the kernel to load, regardless of if I used the instructions for wubu or not.

Ubuntu Installation :: New Kernel Updates Don't Show Up In GRUB Or Boot

Mar 9, 2010

I'm currently running Karmic 9.10 in dual boot with Windows 2000. My computer has automatically updated and installed kernels 2.6.31-17, -19 and -20 (They show up in Synaptic as installed).

However, the newest kernel choice in my GRUB menu is 2.6.31-16-generic (followed by -15 and -14). These all start without any errors.

Question: Why haven't the newer updates shown up in GRUB for booting purposes?

Could it be a question that I didn't answer correctly some time back about accepting or not accepting an update or change in GRUB?

How can this be changed? The new kernels do not show up in Start-Up Manager either.

Debian :: Grub Screen At Startup With Dual Boot Lenny And Karmic Koala

Feb 1, 2010

I have a laptop with Karmic Koala in dual boot with Lenny. I need to reinstall Lenny however if I do that I will loose Karmic Koala in the grub screen because of the new version of grub that comes with Karmic Koala. Which means that I will need to reinstall Karmic Koala after Lenny so that they both appear in the grub screen at startup. If I reinstall only Lenny is it possible to use Gparted to change the boot back to Karmic Koala and have them both in the grub screen again? Or is there another way around it?

Fedora :: After Installing Updates, F13 Goes To Garbled Screen After GRUB

Jun 3, 2010

After applying the latest round of updates last night, I turned on my laptop this AM (ATI X1300 Mobility graphics running the default drivers), selected the latest kernel in GRUB, and waited to log in....only problem is that instead of seeing a normal loading screen (Blue with Fedora icon filling in), I instead get a black screen mostly covered in multicolored rectangles. I don't believe there was a graphics driver update, so I'm rather confused as to what went wrong/how to procede. I can still boot using a previous kernel.

Debian Installation :: GRUB Unhelpful Rescue Mode After Updates

Jul 18, 2010

Today it happened again: After an apparently trivial update Grub (Grub2) enters rescue mode the next time booting, not displaying any useful help whatsoever at that point. (Remember that at boot time no manual or help pages are available.) I don't know what went wrong, but ... The harddisk or partition in question is now no longer a bootable partition.

I don't want to use much time trying to sort out things, so unless someone may direct me to at better procedure, I am going to save whatever can be saved from the hd and then reinstall debian (in this case: Sqeeze) from scratch. Nothing else has in my experience ever worked before.

Fedora :: Dual Booting - Grub Keeps Adding New Entries On Updates

Aug 21, 2011

I'm kinda new to Linux. My problem is that a new Fedora O/S entry is added onto grub everytime I receive an update on Fedora (I think). Eg:

Fedora 15 15.40.0-4 ...
Fedora 15 15.40.0-3 ...
Fedora 15 15.38.0-0 ...
Windows 7

How do I stop this? Ideally I'll only have two entries, Fedora 15 and Windows 7 where Windows is set as the default primary o/s to boot up. The current method I use is to fiddle around with that grub file and set default to entry 3, which used to be Windows 7 but is now a Fedora (which means Fedora is now set to default boot up).

General :: Make Grub Keep Its Default Boot Under Kernel Updates?

Jan 30, 2010

I dual-boot my machine and I want it to default to boot into windows so that whenever I restart the machine remotely from my home it will be able to get back into Windows (instead of Ubuntu).

The problem is that every time Ubuntu upgrades the kernel, I have to reset the default boot item of grub back to windows. This is because the grub menu loader uses positions i.e. 6 for default OS to boot. And when Ubuntu installs a new kernel it changes that order.

I am looking for a way to configure grub to remember its default boot item under kernel updates.
