Ubuntu :: Grub Got Messed Up On Triple-boot System, Can't Boot Anything?
May 10, 2011I'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.
OpenSUSE Install :: Upgrade 11.1 To 11.2 Messed Up Boot/grub?
Nov 27, 2009I just did an upgrade from 11.1 to 11.2 and can not boot to OpenSUSE any more. That happened when the first reboot was starting after finishing the upgrade from the DVD. I tried to find the issue and use the repair system with no luck yet. Now I get no gfx for grub
The only thing I managed is to add the windows boot section for windows but I can not seem to boot to opensuse. device.map:

Ubuntu / Apple :: Install With REFIt On MacBook Pro: Grub Apparently Messed Up My Windows 7 Boot?
Mar 10, 2011This 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 Messed Up - Error: Can't Find GRUB Drive For /sdd1
Jan 31, 2010I'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 Installation :: Messed Up GRUB After Upgrading 10.10 To 11.04?
Mar 7, 2011So, 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.

Jul 14, 2011I 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 :: Fedora's Grub Messed Up Login Splash Screen?
Jun 4, 2011I 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?

Oct 14, 2010I 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.
General :: Messed UP Boot Order On Dual Boot
Jun 24, 2011I am working on another's Dell Inspiron 530 with Vista 64-bit; see below:
[code]....
wanting a dual-boot, 500GB hdd was formatted as above, Win Vista x64 Recovery CD was created, and antiX-M11 (as Swift Linux 0_1_1) installed. Now, at startup, machine boots to antiX and not Vista. User wants it the other way around. I think I should have reordered the partitions and not installed GRUB in MBR. EasyBCD is the preferred boot loader for User. This is a learning experience but due to time constraints and not being at my home where references are available, EasyBCD is on a USB stick -- should I boot to the Vista Recovery CD and then try to install EasyBCD to sda3 from it, uninstall antiX (but this will not fix the MBR problem, will it?), or edit fstab or what
Ubuntu :: Hangs On Boot (but Also Messed Up Different OS)?
Sep 1, 2010My old man wanted to try linux, and he got an Ubuntu install (ill check version tomorrow).Anyways, we installed it, but during boot of either it (going though a boot slector menu, hitting F it shows only two lines on the screen (something vaguely similar too):GRUB loading stage1.5GRUB error 21 (or 27 cant quite remeber)
I did, unfortunately, have to step out while it installed leaving him at the helm. now the main problem is this: Ubuntu will not boot, and neither will the previous (contained on a totally different harddrive) Windows XP. A third OS (Vista) still boots, but unfortunately my dad had all his apps on his XP drive. Now, the ubuntu we put on a third Hharddrive (Both Vista and XP boot from two IDE docks in the machine (one Primary master and one secondary master)), but the ubuntu was installed on an enclosed (In the case) SATA drive partition. it seemed to have installed but when selecting to boot form it, or the harddrive with the XP system, i get the above error. however, vista boots completely without problems. Anyone ever seen sometihng like this? the computer responds to no commands beyond ctrl-alt-delete at this lock up, and no dos/command prompt opens up. it just sits there at these two lines until either ctrl=alt=delete or a hard reset are pressed.

Dec 18, 2009My 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, 2010I 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 ?
Ubuntu Installation :: Messed Up Hard Drive In Dual Boot Attempt?
Jul 28, 2011I was attempting dual boot my computer (ubuntu 11.04 and windows 7) and when I got to the stage to allocate drive space I accidentally formatted the largest partition of my hard drive to a linux swap. My computer froze while it was formatting the drive and I was forced to power off my laptop. Windows was my original operating system and was installed on the partition that is now formatted (or maybe not because of the crash during the formatting) as a linux swap. Therefore my windows no longer works and I cannot restore my computer for a backup because it wont let me restore it to the partition that is now a linux swap. Now when I boot from the linux install cd I get an error and am not able to install ubuntu or format/allocate drive space. Is there a way I can reformat and fix my harddrive so I can them restore windows.

Nov 29, 2010i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file

Jul 2, 2010I messed up my install so now I can't boot it. I get errors. I doubt I'll be able to fix it. I messed up the upgrade of the kernel images... I'm not sure whether there's something I could do in the Grub config file... I have one other Linux OS I can use in the meantime (plus Windows OS) so I thought maybe boot that up and check the Debian partition in case there's any files I want to save/keep. If I re-install, is Debian Squeeze LXDE still a good choice? I'm going to install something different in the partition where the other Linux OS is. Right now, it's grub is handling the boot loader. The computer is an old laptop, a Thinkpad T41. The HDD is 160GB.

Ubuntu :: Get The Version Of GRUB / GRUB-legacy To Boot Any Recent Windows 64 Beyond XP (Vista Or 7)
Dec 20, 2010I've been using Linux for over a decade, so no need to worry about the obvious. I'm positive that I have my partitions/install correct. What has me baffled is that Fedora 14, which uses GRUB 0.97 (GRUB legacy) - boots Windows flawlessly every single time on the same hardware, but Ubuntu's (or the upstream Debian's) GRUB legacy do not - even though they are based on the same upstream code from the GNU Savannah servers.
No matter what I've tried I cannot get the Debian or Ubuntu version of GRUB/GRUB-legacy to boot any recent Windows 64 beyond XP (Vista or 7). All that it does is resets the computer when Windows attempts to boot, without an error. GRUB is notoriously difficult to compile, so before I try to compile code from RedHat's archives - any thoughts,experiences, similar issues - whatever?
