Ubuntu :: Grub And MBR Messed Up After Windows Update

Jul 14, 2011

I just started using Ubuntu 10.04 for development reasons and installed Ubuntu on a seperate harddrive with dualboot option with Windows 7.Today Win 7 got an update and I mysteriously got bumped back to the grub screen after selecting Windows boot option, but my Ubuntu was ok. After that I probably did the worst I could, and googled the problem and tried out some years-old advices which messed up my ubuntu boot as well.I am currently using my computer through Ubuntu Live Usb.

Ubuntu :: Grub Messed Up - Error: Can't Find GRUB Drive For /sdd1

Jan 31, 2010

I've trawled the internet but can't seem to find the exact same issue, so I've made a new thread. So, I installed Ubuntu onto a 160gb drive. I have other drives in the system, but I disconnected them so that the system drive would be sda. Ubuntu installed perfectly with no issues whatsoever. I connected the other drives in the system, and again it booted up perfectly (although I can't remember whether the 160gb drive remained as sda or became sdd). Then I attached some extra drives temporarily to do some data shuffling.

This moved my system drive to become sdf. My computer booted fine multiple times like this, but when I was finished with the drives I rebooted and suddenly everything broke. For some reason my ubuntu installation showed up in the GRUB twice, and neither of them booted. So, I popped in the Live CD (which I'm using to type this post), and decided to update the grub. I chrooted into my system drive and ran update-grub, but it simply returned something like this:

Ubuntu :: Update Messed Up Graphics?

Jun 7, 2010

I'm not sure why this is so difficult. I decided to upgrade to 10.04 from 9.04 after an update messed up my graphics and I had to get some work done rather then sift threw a mound of sparsely detailed possibilities. Also I'm not an leet coder.

So really I've installed 10.04 on many machine's with many different video card's and many different monitors. But to some magnificently obscure reason I'm unable to set the correct resolution on any single computer. Ati, Nvidia. Not intel on second though.

I've managed to scrounge up some tidbits of info on the new KMS (kernel-mode-setting) technology. I've run threw a few suggestions threw out the forums and across the net. I've tried al sorts of drivers. I've tried removing the xorg.conf but I've seen little info on why that is other then it is not needed. I've added things to /etc/default/grub, I've removed things. I've gone threw synaptic and removed everything Nvidia and reinstalled it. This by the way is always off a fresh install every time.

So here it is. I'm at the end of my rope. I know this must be some new way of doing things but It just seems odd that every computer I've tried has failed me. I need the correct resolution to work. I can't keep burning the eye's out of my head looking for possible solutions on crappy resolutions.

I'm sorry for the rant. I'm frustrated and seriously considering switching to Redhat despite having to pay for there service's. Could anyone shed some light on my gloomy situation. I want to keep promoting Ubuntu with out saying "if you can get such and such working"

Ubuntu Installation :: Messed Up GRUB After Upgrading 10.10 To 11.04?

Mar 7, 2011

So, I had Win7 and Ubuntu 10.10 in dualboot and after upgrading to 11.04 I managed to screw up GRUB, it didnt boot into Win7 anymore. After that I got rid of both ubuntu and swap partitions and merged them to Win7 partition via Gparted and made a clean installation of 10.10 again next to existing Win7 hoping to fix GRUB and be able to boot into Win7, but now when I try to boot into Win7, I only see '_' blinking on top left and nothing happens, Ubuntu works fine.

Ubuntu :: Fedora's Grub Messed Up Login Splash Screen?

Jun 4, 2011

I installed Fedora on a separate partition and during the install prompts forgot to uncheck the Grub installation. So, Fedora installed with Grub 1 (imagine that) although I was able to find instructions to upgrade it to Grub 2 (plus it recognized all the OS on the computer). So far so good, I don't have a preference whether Fedora's or Ubuntu's Grub is installed, however the Ubuntu Startup Splash screen is messed up, ie. a simple purple background with "Ubuntu" in system fonts. Is there a way to fix this back to the graceful default splash screen? Can I change back the Grub to be Ubuntu's?

General :: Kubuntu 10.10 Installation Messed Up Grub

Oct 14, 2010

I have used openSUSE for a long time, but was trying to install Kubuntu 10.10 in addition to opensuse 11.3 and Windows 7 on a Gateway desktop (1500 GB hard disk & an external drive with 1000 GB. From the CD with the isoimage I got the live version and then decided to press install. I chose to follow the suggested choice of partition: About half of the external drive (500 GB) was allocated to Kubuntu while the internal hard drive contained Windows 7 and opensuse.
Everything went well until I was asked to restart the computer. I got a black screen with the message:

error: no such device: 64e3ffcl-c003-482a-87f3-89489e5e067d. grub rescue> At this point the only command that will not respond with Unknown command .. is 'ls' which gives: (hd0) (hd0,msdos9) ... (hd0,msdos1) (hd1) (hd1,msdos2) (hd1,msdos1) (fd0) (fd1)

I am now ***completely lost***. The only step that gets me out of this screen is ctrl-alt-del which causes a reboot and brings me back into the same situation. The ***computer is useless*** until this is resolved.

Fedora :: F12 Update Messed Up Boot And Apps

Dec 18, 2009

My computer is a dual boot between windows xp and fedora 12. I am using grub and my first boot selection default was windows. My computer has the following specs:
-AMD athlon xp 2400+ at stock speed 2.0Ghz
-640mb of ram, 2x256mb, 1x128mb, all 266mhz speed
-250gb SATA harddrive, seagate
-Nvidia GeForce 4mx AGP video card
-ASUS A7V600 rev. 1.00 motherboard

I booted up fedora 12 today(12/17/2009) and did a fedora software update (task bar->system->administration->software update). It said it found 94 new updates release on (12/16/09), so click update, and the computer did its updates and reboot. Now my grub boot loader is messed up (boot default was windows, now its not) and random apps crash, like gedit, so I can't edit my grub settings to boot to windows and linux is now useless because apps keep crashing. As of right now I am using another computer to post this. I know one of the updates was a Fedora 12 kernel update. And the new updated fedora 12 "automatic bug reporting tool" does not work any more, after the update.

Some ideas I have, but I have no idea how to do them:
-uninstall last updates
-repairand/or restore bad files
This is important because I need to use some of the apps/programs for work.

Slackware :: After Update To Current Boot Is All Messed Up?

Jan 26, 2010

I have just updated current to get the new kernel and things seem to have gone just a little wrong.After upgrading i edited lilo.conf and ran all seemed fine so i rebooted to find my pc wont boot it cannot find modules and there will be trouble ahead it think it says (will check the error and add it).So i thought no problem i can just boot from an old disk i have laying around and fix it from there. I only had the 12.2 install disk or ubuntu 8.10 live cd neither of witch support ext4 which i stupidly decided to format my drives in.

Anyways i now have a ubuntu 9.10 disk and have booted and try to fix things but am miffed at whats going on. If i chroot into my slack root and look in my /boot there is only the old files before the update, but if i mount the drive in ubuntu there are the new files from after the update.What has happened and how can i fix it? It has just occurred to me i could use a tmp dir and copy the correct /boot files there then in the chroot copy them to /boot may work ?

Debian Multimedia :: Desktop Messed Up After Nvidia Update?

Mar 27, 2011

system update today which moved the nvidia drivers from 195 to 260.After performing the update with synaptic and restarting, I noticed that my desktop theme, "Clearlooks," was messed up in that the shiny progress band was now two separate colours (blue and white). Tried other themes (among them "Glossy") and found most of them corrupted with, for example, the progress bar totally white.Similar problem with Iceweasel 4: the tabs have lost their inferior border, and the address/search bars are surrounded by white.I suspect (though I can't be sure) that the above is caused by the nvidia update. I did an "nvidia-xconfig" to try and see if this would change things, but no.

Ubuntu / Apple :: Install With REFIt On MacBook Pro: Grub Apparently Messed Up My Windows 7 Boot?

Mar 10, 2011

This seems to be a variant of a problem many people have had, but after several hours trawling through various forums, I haven't seen a reliable match for my situation.In brief:Adding a third boot partition (of Ubuntu) to my existing dual boot of OSX 10.6 and Windows 7 seems to have crippled the Windows boot from working, because Grub apparently takes over the process. Yet Grub does *not* appear to be on the Windows partition.

More verbose:I have an older MacBook Pro (3.1, running Snow Leopard) that I recently refitted with a new 240GB SSD HD. With the extra space (it was previously only 120GB) I decided to add a dual boot with Windows 7 using bootcamp. This all went swimmingly well.Encouraged, I decided to follow this Lifehacker article's suggestion and triple-boot the machine with Ubuntu (I'd never used Linux before):So I now have the nice rEFIt boot partition selection screen, and, indeed, I'm up and running in Ubuntu, and enjoying it.

Only one problem: I can't get into Windows any more. If I try to go in through rEFIt *or* by holding down OPT at startup and selecting the windows partition directly, the result is the same: I get thrown into Grub's selector, and selecting the Windows partition from there leads to an error message and a dead end.Having read through numerous postings, I get the impression that Grub is doing something or living somewhere that it ought not to be, but in most cases I've seen, people had accidentally installed Grub onto the Windows partition (or indeed onto EVERY partition). So far as I can tell, this isn't the case with me. Here's my boot summary:

Ubuntu :: Grub Got Messed Up On Triple-boot System, Can't Boot Anything?

May 10, 2011

I'm currently on a work trip with my Asus G72GX laptop for non-work use (I'm posting from my work laptop). Yesterday, I accidentally booted into my laptop's recovery partition (from the Grub2 bootloader). Before I realized that that's what was happening, it booted into some kind of recovery program which ended up in an error. I restarted the laptop and couldn't get into the bootloader anymore. Now, the only thing that comes up is an error -- "error: unknown filesystem." Below that, it gives me the "grub rescue>" prompt. Most of the commands that sites list for grub rescue only return "Unknown command". ls works and lists all of my partitions: (hd0), (hd0,msdos, (hd0,msdos7), etc. down to msdos1. When I "ls (hd0,msdos" (etc, etc) it says "error: unknown filesystem."

I then started looking into booting from a Live Ubuntu USB drive. I've tried 11.04 and 10.04 now and they both do the same thing. I put them on an 8GB flash drive (only 1 at any given time) using Universal USB Installer and was able to get to the Ubuntu menu (Run Ubuntu from this USB, Install Ubuntu on a Hard Disk, etc.) If I try either "Run Ubuntu" or "Install Ubuntu", the screen flickers and comes right back to that menu.BTW, my 3 operating systems are: Windows 7 HP 64-bit, Mythbuntu 10.10 64-bit, and Windows XP 32-bit. Laptop hardware: Core 2 Duo P8700 2.53GHz, 6GB RAM, Nvidia 8800 GTX video card.

Ubuntu :: Booting From NForce FakeRAID - Hand Correct Grub.cfg After Update-grub?

Mar 5, 2011

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:

menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext2
set root='(/dev/mapper/nvidia_caifaefg,msdos5)'


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?

Mar 4, 2011

I have 2 hard disks. sda,sdb

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.

Chose advanced istall

Selected sdb3 for Ubuntu

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.

Ubuntu :: No Bootloader After Kernel Update - Update-grub Hangs

Dec 1, 2010

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:

Ubuntu :: Grub Prompt Appears After Update-grub?

May 6, 2011

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?

After that I ran...
