I recently installed Ubuntu 10.04 via Wubi installer. When I updated it, I got a pop up asking me to Continue without updating grub. So I continued and I see that I still have the old GRUB version. How to update to the latest version of GRUB?
Edit: when I boot, at the top I see : "GNU GRUB Version 1.98-1ubuntu5"
Then below I see ubuntu,linux 2.6.32-22-generic.
Is that the latest version?
after doing an upgrade to 10.4 and updating grub I get this message. how do I address this
[Code]...
I was unaware of the difficulties of installing and booting Ubuntu from the "onboard raid" that the NVIDIA nForce chipsets provide. However, I've managed to get it working reliably with one single caveat:
When update-grub builds the grub.cfg, it refers to all of my partitions as follows:
Code:
menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod part_msdos
insmod ext2
set root='(/dev/mapper/nvidia_caifaefg,msdos5)'
[Code]...
So I'm guessing that the whole nvidia_blah,msdos5 is because of that. However, it doesn't seem to explain why Grub would THINK that would work and it in fact does not work. That's the biggest source of confusion on my part.
My questions are as follows: First off, because as an IT person I want to know: Why does this sort of change work? What does changing that device name change in GRUB's behavior? Is there a setting in /etc/default/grub that would change the way it's naming these RAID devices? Is there a value for this setting that would give me the device names that work, as explained above?
If there is no setting change I can make in /etc/default/grub, could I add a sed command on to the end of update-grub or can I make a modification to one of the scripts in /etc/grub.d? What sort of change would be recommended? How would I preserve this change through later package upgrades that would possibly rewrite these files?
I have an old BIOS (only 149 GB detected in 160 GB drive). I have installed very few OS as a result - Windows in first 80 GB , 2 distros (20 GB each) in next 40 MB which is within the 149 GB. On issue of "update-grub" grub seems to detect all OS and generates grub.cfg. But on boot , one distro does not appear in the menu.

In sda, I have 4 partitions, and I have windows 7 in one of the extended partitions [not in the primary partition].
In sdb, I have 3 partitions. 2 for storage, and 1 10GB drive for Ubuntu. Again, Ubuntu is not of a primary partition.
I had ubuntu 10.04 running on that for a long time. However, I wanted to reinstall ubuntu and use 10.10.This is what I did EXACTLY:Booted from Ubuntu install CD

I installed GRUB2 on the SAME partition as Ubuntu aka sdb3 Installed then rebooted
I can boot into Ubuntu fine, but whenever I select Windows 7 bootloader from the GRUB menu, the screen goes black, and my PC reboots.

I have tried the testdisk/update-grub method, but it didn't work.
Ran the updater, went to boot to Win7 to use Photoshop and realized that the grub menu was gone. Ubuntu boots by default now. I tried running "sudo update-grub" at a virtual terminal and while it listed the various linux kernels ok, it then got caught in a loop spitting out some crazy looking errors. I rebooted and Ubuntu came up fine. I tried running "sudo update-grub" again from the gnome terminal and it hangs the whole computer for a few minutes and finally gives me this:

I've been trying change the default OS in GRUB. I changed the value for GRUB_DEFAULT in etc/default/grub. However, when I run update-grub, I get the following error:
/etc/default/grub: 19: e: not found
I updated my grub yesterday using the command:
Quote:
sudo grub-update
and I rebooted and grub menu not coming now. I have a dual boot with Win7. Ubuntu 10.04 is installed with WUBI. I can run WIN7 but can't run Ubuntu now.
After certain system-wide changes, like kernels updates, I obtain grub prompt on restart. However, if I put the hard drive into another computer (b), it boots up fine. Since, however, I use the present computer (a) regularly, I only use b to purge and reinstall grub using the chroot method. However, doing so every time is time consuming; and I cannot change anything in the defaults and run update-grub without obtaining a grub prompt on restart. How do I fix this?
View 9 Replies View RelatedI'm trying to edit my Grub menu by removing the older kernel after I ran updates as well as make my Windows 7 install first on the list.
I ran...
Code:
sudo gedit /boot/grub/menu.lst
and edited it accordingly.
After that I ran...
Code:
sudo update-grub
I restarted and see no changes on my grub menu. Running 1.97 beta4 if it makes a difference.
Oh and btw I am a complete n00b with linux.
When I attempt to update GRUB in Ubuntu 10.04 with the following command in terminal:$ sudo update-grub

I have ubuntu 10.04 on a dual boot with win XP.And lucid has definately made me forget XP...
I regularly update ubuntu. Each time i update ubuntu and restart the machine there is a new entry added in the grub 2.Now its showing three entries of ubuntu!
For eg..now i have the grub showing
So each time i upgrade a new entry will be made and list larger..now how do i cope with this.Are those entries kept in case i want a roll back.
I did a system update and it did something to the grub loader and now all I can select is my windows partition. I'm not really sure how to go about restoring my grub loader. I had ubuntu 10.04.

GRUB upgrade scripts have detected a GRUB Legacy setup in /boot/grub.
In order to replace the Legacy version of GRUB in your system, it is recommended that /boot/grub/menu.lst is adjusted to chainload GRUB 2 from your existing GRUB Legacy setup. This step may be automatically performed now. It's recommended that you accept chainloading GRUB 2 from menu.lst, and verify that your new GRUB 2 setup is functional for you, before you install it directly to your MBR (Master Boot Record). In either case, whenever you want GRUB 2 to be loaded directly from MBR, you can do so by issuing (as root) the following command: <ok>
I do not even use grub. I launch ubuntu from another partition. I do not know of a way to delete grub. Is there a way out of this?
2. How do you boot into terminal mode?
I had Windoze 7 on my wife's laptop, it started running crappy so I install Ubuntu 9.10 via Wubi (so it is not a partitioned dual-boot). I did the latest update, which I think included a kernel update. When I rebooted and chose Ubuntu from the windows dual boot window, instead of loading the GRUB I see an error message flash:
Code:
TRY hd0: NTFS no Wubi(something-or-other)
it flashed almost too fast for me to catch - it took about 10 reboots to figure out that much... and then it goes to a screen that says
Code:
GNU GRUB version 1.97~beta4
sh:grub
I tried several different commands (you can prompt it to give you available commands by hitting TAB), but it said it couldn't detect a kernel. Also, before I updated, I had tried to install iTunes via these instructions. iTunes seemed to have installed fine, but I hadn't tried it yet.
I had a bad experience with 9.04 - I installed some recommended system updates, and the updated GRUB killed my installation (which is WUBI), not letting me boot.
I've now installed 10.04, and some updates have come through, one of which is GRUB. So I'm now looking at the "Configuring grub-pc" dialogue box that's popped up, and there's an option to "Continue without installing GRUB?".
What are the risks here? Is my 10.04 WUBI system going to die if I upgrade GRUB again? Or is it going to die if I don't upgrade GRUB?
I have upgraded from 9.10 to 10.04 but I'm still using Grub1 as I came from 9.04.
Anyway, during the upgrade I kept my original menu.lst file when prompted as I have a Windows XP boot option that I wanted to keep. I have read that this means your kernel won't be updated - and indeed mine wasn't.
The new kernel files (vmlinuz-2.6.32-23-generic) are on my machine in the /boot directory. uname -r currently shows 2.6.31-20-generic.
From what I've read you should just need to run update-grub manually and it will install. However, I have done this but it isn't upgraded. It doesn't modify my menu.lst or anything.
Output for update-grub:
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
[Code].....
So it says its updating menu.lst but there is still no entry for 2.6.32-23? Am I missing something?
I've done my due diligence, but I'm tired and frustrated so my googlefu probably isn't up to par at the moment! Been running Ubuntu as my main OS for about a year now, and have been really happy with it. So far I've been able to find solutions to every problem I've had, but I think this one's got me a bit out of my depth. I REALLY don't want to have to reinstall, I'm currently running Lucid as the only OS on this machine, and about an hour ago I installed the most recent updates as provided by the update manager. On reboot, it stopped at a GRUB command line.
I've managed to boot back into Ubuntu by manually loading the linux module etc. and booting. From there I've tried updating grub, and reinstalling grub (No errors on reinstall) but nothing persists. I've taken a quick look at the grub.cfg, but TBH I'm not sure what I'm looking for! [edit] FWIW, I have GRUB 1.981ubuntu7 installed
In 9.10 after kernel update there was always prompt window if i want to do changes in grub config file. In 10.04 there's no such question and every time i do update i have to edit my grub config file in order to get rid of older kernels and set windows as second position in boot menu. why does it happen and how to stop updates overwrite my grub config?

View 1 Replies View RelatedWhilst I've been using Ubuntu for years now, I don't really do much at the command-line, basically because I don't *have* to (which, to me is the beauty of this OS!). However, the last update via update manager has rendered my dual-boot with Vista on an Asus laptop non-functioning (at least Linux). What happens is this: after the BIOS splash screen, it says starting GRUB and then, instead of a menu of current and recent Linux versions and the Vista option at the bottom (white text against colour background) it now just shows one line of the menu in magenta... the rest of the menu is black, but the arrow keys will show the other options. Hitting ENTER does nothing: the text line is replaced with a blinking underline which goes back to the text in magenta again when i hit ESC. I can't seem to ESC or SHIFT to GRUB's command-line prompt at all. I've boot to the LiveCD and ran a boot_info_script in bash: here is what that revealed:

I have Ubuntu 10.10 installed on my machine and recently I have been having the following problem:
Whenever I shut down my PC and boot it up again, I get to the Initial menu where it asks if you want to run Ubuntu, Ubuntu safe mode etc... I hit enter and then there's just a black screen.
I then have to restart, run Ubuntu in safe mode and update GRUB. After this It boots up fine.
So, is this a software issue? Is it an issue with my HDD or is it something even worse?
I had to restart my server after it became unstable - strange things like couldn't connect from a Windows machine, becoming unresponsive. When it rebooted, it failed with grub error 18 (this after the machine has been fine for some considerable time, including rebooting).I ran apt-get upgrade shortly before my problems started, and google suggests that I'm not the only one to get this error after apt-get upgrade, but I can't find a solution.I really, really don't want to have to rebuild this machine! I can get in using the recover a broken system option on the install CD - the disk seems fine.
View 6 Replies View RelatedI foolishly let Ubuntu update grub yesterday on my Wubi installation and now cannot boot:First I get the error:Error: unknown command - loadfront.Error: File not found then the system reboots almost immediately so there is no chance to get to the grub prompt.I assume my choices are 1) restore from backup (I have one) or 2) boot from a LiveCD and edit grub (I don't know what changes to make).
But I would rather be able to update grub in the future along with other Ubuntu updates, so I'm really hoping someone knows what the error is in this last update and whether it will be fixed.

I'm running Ubuntu 10.04LTS, which I installed just over a month ago, from the 10.04.1 maintenance release livecd. This is a brand new PC and I'm not dual booting.
I've just done an update via the "update manager" and following the security and normal package updates, I'm greeted with the following message to do with grub-pc (and I believe grub-common is also being updated).

I'm not sure why I'm getting this message, as I've yet to change anything to do with grub and the only alterations I've made so far, are adding some of my favorite applications, changing the theme, wallpaper, added codecs, fonts, Etc..... Definitely nothing to do with any configuration files.
I'm a little reluctant to proceed without a little advice, as the last time I encountered something similar, I encountered a nightmare getting my system to boot again. The other reason for asking for advice, is so that other newbies encountering this might be able to find an answer to this issue.
After upgrading Maverick (perfect!) to Natty, I was unable to boot into anything. (kernel 2.6.38). However, through much PITA, I was able to boot into an older kernel. (2.6.35). I completely removed 2.6.38, rebooted, reinstalled it and ran update-grub. However, 2.6.38 is no longer available no matter how many times I run update-grub, and the only option left is 2.6.35. In my humble opinion, the Natty upgrade experience is rubbish. (blank screen, total PC hangs, boots into a blank screen with only a blinking cursor, NVIDIA official driver not working, bootable only into older kernels etc.)
