So I had Ubuntu Server installed and I decided to make some new partitions using gparted via a live usb of Ubuntu desktop. And so I think messed up pretty badly. Ubuntu Server won't boot and I get the following error followed by a grub rescue promt:
Code:Diskette drive 0 seek failure
error: file not found grub rescue >
To me, it seems like some boot files may be missing if not the whole system. After I made the partitions, the live USB of Ubuntu was still working fine until I rebooted.So here is the bigger issue, I figured I would just reinstall everything all over again, but instead I can't.
I had 250gb hard disk with dual boot, xp and ubuntu 10.10.Yesterday, i tried to upgarde my ubuntu 10 to 11 from a live cd....b4 doing so, i used a win software EasyBCD to fix the mbr but it didn't work properly..and i ignored it(my biggest mistake)and deleted the ubuntu partion from the windows device manager. It just displays "Booting from Live CD" for few minutes and again displyas the same above error.What should i do now?Its ok if i m not able to recover my data back...i hv sycnd my docs on the internet.
I had Ubuntu installed, i installed Debian and there was no dual boot. So i formated all the hard disk to install only Debian. It installed but at boot i get error: no such device and the grub rescue> prompt. i googled for a solution and nothing worked:
- i tryed reinstalling grub, not worked - i did the windows cd fixmbr trick, not worked - reinstalled debian with fixmbr the first step and nothing - tryed deleting with dd the mbr, not worked - reinstalled grub from debian rescue, not worked
what should i do? i can't access my computer? please tell me how should i fix it? the google guys will kill me because i put their servers on fire
i have dual booted ubuntu with windows. but after a few days i realized that ubuntu was too slow for my system and then decided to uninstall it and planned on installing it later. So i deleted the partitions on which ubuntu was installed. I rebooted the system and the grub rescue promt appeared, i already knew the work around was to restore the windows MBR using the live cd i used to install ubuntu or the Windows installer. But the main problem is my DVD suddenly stopped working . So my question is, can i boot windows using the promt? is there any commands? or can i uninstall grub using the rescue promt?
I have a laptop with Windows 7, and about a week ago I installed Ubuntu 10.10 64-bit via LiLi USB creator. Worked beautifully, but I was having some issues with the brightness controls so I decided to get cute and upgrade to 11.04. So I downloaded the beta2 and used LiLi to make the USB (unsupported for that version of course) which used the same parameters as 10.10. I then tried to do a fresh install over the partition I had set aside for Ubuntu and had 10.10 installed on (~80 GB).
So in the installation itself, something got majorly screwed, and the entire system froze. Next thing I knew, I was rebooting and got the Grub Rescue prompt and no ability to load into either my old Ubuntu 10.10 or my new failed 11.04, or of course my Windows 7 partition either. The partition is obviously there, and as I only have one PC in my house, with no Windows 7 recovery discs, I currently cannot fix the mbr to just get my Windows back. I can of course get this in a couple days, but I'd like to be able to fix this without going to my parents.

Those are my partitions. /dev/sda3 is my Windows Partition, which I want to boot from. Only problem is, I'm not really sure where the computer is looking to find the boot record. I think it's from my fubarred /dev/sda4 partition which means it's basically looking nowhere. So I can't modify it to point to my Windows so I can just get back there.
I just installed Ubuntu 9.10 on hd1 - /dev/sdb1 at the end of the installation I chose to install grub at hd0 - /dev/sda1. The file system I chose was ext4 for ubuntu "/" - 50 GB, ext3 for "/home" - 5 GB, and 1.5 more for swap. When the installation was complete I got the following prompt:
GRUB loading error: no such disk grub rescue> >
There was nothing I could do, pressing TAB did not show me all the commands like grub is expected to. Typing 'help' did not show any commands as well, instead it showed me - "NO SUCH COMMAND" or something like that (I did not took note of what the output was). I believe the problem is in the grub loader - which was not really installed properly in hd0 - /dev/sda1 (which is FAT32 - windows)
i have a dual booting the first one being ubuntu 10.04 within which i have installed windows7.Unfortunately,i've formatted that part of my hard disk in which i've had ubuntu. Now my problem is i cant load into any of the two os and i dont want to loose my vital data in the system.I've tried booting using the live CD but in vain.i desperately need my info in my laptop.
Recently I messed up GRUB boot loader in my laptop installed with Ubuntu which resulted in grub rescue prompt. So I had to boot Ubuntu Live CD to get it fixed. Thought of blogging it, may be useful for some one.
This fix involves two steps. First one is to chroot into Ubuntu installation partition. Second one is to install the grub MBR (Master Boot Record). I am using Ubuntu Lucid 10.04 and Live CD also of same.
Installed 10.04 on my daughters laptop from within windows Vista. All went OK but I had two boot loaders, i.e. turn on laptop and I would get the Windows loader asking if I want to boot in to windows or Ubuntu. Upon selecting ubuntu I would get the standard grub loader that I have on my PC. Did an update a few mins ago and it asked me to update grub which I did and as there was only one disk showing clicked forward. Now on reboot I have grub rescue prompt, no such device. Hard drive is a single 80 gig drive with windows on one partition and ubuntu in another. Have the live cd so can boot from that I guess. What do I do next?
When I try to boot I only get to the grub rescue prompt doesn't matter if I try booting from ubuntu 11.04 cd windows 7 disc or the hard drive. At the moment ubuntu 11.04 should be installed although it gave me a ton of errors as I installed it and as soon as i restarted the computer i got this prompt.
So I wanted to get rid of ubuntu 10.10 on my HP pavilion dv6 laptop as I wanted to make some hd space. Its a dual boot with windows 7. I deleted the ubuntu partition and expanded the windows partition to fill the whole hard drive again. When I restarted my laptop I got the "error: no such partition. Grub rescue>" message.
I tried inserting my ubuntu 10.10 boot cd but whenever I boot from the cd I get the exact same grub rescue error. Is it possible to remedy this situation from the error? I am currently unable to download a windows recovery cd so I'm stuck in the grub rescue page unless its possible to fix this mess from the error prompt.
Have installed ubuntu on a separate partition on single hard disk and system initially worked on a dual boot basis with windows xp. However after installing most recent series of updates computer is failing to boot.
Error message is 'error : no such device : 6937cabe-f115-455b-a248-6f8d46f80682.' prompt showing is 'grub rescue>' am now unable to access either windows or ubuntu.
I was dual-booting Ubuntu 11.04 just fine for about the last week but then ran into some issues and decided to reinstall Ubuntu. Now after the install I get this error: error: nu such device: d38af2a9-740e-4d3c-b267-2a3848e5d319 and it goes into the grub rescue command prompt screen. I have tried to reinstall Ubuntu about 6 times now, complete installs. I have tried changing boot priority multiple times. I installed off a thumb drive and left the thumb drive in after install, took it out after install.
I'm having a issue. It first started a few nights ago, and after booting from the live cd and reading around, I saw it mentioned somewhere that it might help to update GRUB. I did this using sudo update-grub. This took care of the issue, with an unexpected, but not altogether unwanted result: instead of having to choose a temporary boot device to boot on to the external drive Ubuntu is on, I got a grub menu which showed the the OSs for both HDDS. I thought all was fine, but a few days later, same thing. Updated grub again, and all was okay. Tonight, it happened again.
When I try to update grub now it says: Code: ubuntu@ubuntu:~$ sudo update-grub /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
Here's the result of the boot info script. Code: Boot Info Script 0.55 dated February 15th, 2010 Boot Info Summary => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #1 for (,msdos1)/boot/grub. => No boot loader is installed in the MBR of /dev/sdb .....
Just did a full install of the latest version of Ubuntu. I've got a high-end alienware m17x laptop with dual SSD drives in a raid array. Ubuntu installed fine, but when I reboot, I get to a grub rescue prompt and it never gets to desktop. I'm booting from the liveCD while I try to figure out how to fix it.
I updated yesterday and now when I start my laptop it goes in to grub rescue mode. I have booted from a 'live cd' and thought I could repair grub from there. In gparted however the partition with ubuntu (sda1) is seen as unknown file system, in terminal when I list the partition table it shows up as FAT16 type. When I try a grub-install it gives this error message:
i am a newbie to linux and i am stuck at the GRUB rescue prompt at the startup.i have dual boot windows and Ubntu 10.04.I want to remove GRUB2 from Harddrive itself.can u suggest ant command on GRUUB recue prompt ?
I have two hard-drives. The first, C: (sda1) has Windows 7 x64 installed on it. The second hard-drive, D: (sdb1), was partitioned when I installed Ubuntu 10.04 into two separate partitions: NTFS and Ext3.
I wanted to remove the Ext3/Ubuntu partition and reclaim that space (i.e. completely remove Ubuntu). I did NOT install using Wubi. I booted up Win7 x64, went into Disk Management, right-clicked the D: partition corresponding to the Ext3 filesystem (shows up as unrecognized in Disk Management), and opted to delete the volume. I then right-clicked on the NTFS D: partition, and opted to Extend the Volume to reclaim the previously partitioned space.
When I rebooted, I ended up with the following error:
Code:
error: no such device: f81368be-ea53-43d2-b8de-bb52b5ac322c. grub rescue>
I cannot get beyond this screen. Rebooting always puts me at the grub rescue prompt. I have looked at the HOWTO: Purge and Grub Rescue Prompt threads, but was not able to understand the instructions and am therefore asking for your help. However, I was able to install the boot script as those threads suggest, and here is my results.txt:

Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #2 for /boot/grub.
I tried to install Ubuntu as a dual-boot on my Windows XP machine, using the USB stick trial OS and automatic installation. My screw-up came when I left my external USB hard drive plugged in during the install, and as far as I can tell, Ubuntu was installed on that as opposed to my internal HD. Now when I try to boot, I get knocked straight to the grub rescue prompt with an error message that basically shows my "no such device (my external's ID)" -- assuming that the MBR (which I know nothing about editing) is trying to boot off the external that isn't actually enabled until an OS starts it up, and dumping me at the rescue prompt when it can't find it.
I can still load up the trial Ubuntu off the original USB stick (though can't get online with it without wireless drivers), but that's as functional as the computer gets right now. And I don't have a Windows Setup CD anywhere (using a rooommate's Mac at the moment with a terrible European keyboard on it). So is there any way to edit the MBR or something to tell it to boot my regular XP off my internal HD, at which point I can re-partrition and try this whole thing again, or otherwise remove the failed install of Ubuntu through the trial-stick or... well, I'll leave the suggestions up to you all. I've been working on this since about 4am last night and my brain is kind of fried.
I dual boot Windows 7 and Ubuntu, and recently I updated from 10.04 to 11.04 via live cd. However, I now get the grub rescue prompt instead of the normal grub menu when I boot my computer.
I've got Ubuntu 10.04 installed on one partition, and Windows Vista on another. I was messing around with my partitions, and now I can't boot to either one. I just get an error when I boot up on GRUB which says "error: no such partition", and then a prompt saying 'grub rescue>'. I've read up on other people's posts, and they said that I should reinstall GRUB from a livecd, but that doesn't look like it does anything. It seems that GRUB is trying to boot from hd0,8, and that doesn't exist anymore. I can change the 'root' and 'prefix' variables to the right partitions, but the 'boot' or 'chainloader' command doesn't work. You should be able to boot from 'grub rescue>', because that's what it's for, right?
I just want to be able to boot into Ubuntu, not Windows.
PS: Sorry if I'm specifying way too much information(or not enough), I'm fairly new to forums.
So earlier today I was running out of space on my regular Windows 7 partition and I played around with extending it. I ended up somehow deleting grub and messing up my entire system. I've spent the last 2 hours looking for the answer to this and everyone has been saying to boot from a live disk and fix it that way.
Well, I've tried everything, the only way I can boot right now is via USB and it will NOT allow me to. I checked on other computers and even re-installed and formatted by external hard drive to try and get it to work and it refuses. I've changed my BIOS to boot from USB so I have no idea as to why this is happening. Also, I've tried using the "ls" command to find my partition via "ls (hdX,Y)/" and all of them come up as unknown filesystems.
I have a SONY VAIO CW26 laptop. I got a Windows-7 version prepacked with the laptop.I installed Ubuntu Karmic 9.10 over a new partition that i created using the inbuiltfacility in windows7. Both the operatings systems i.e windows7 and ubuntu karmic 9.1 were working nicely.Today i created 2 more partition within the partition inside windows.Once I rebooted after creation of the new partitions my laptop is just showing a black screen with following message.
First time poster and recent Ubuntu adopter. I recently installed 10.10 on my main HD alongside a separate windows (xp) partition (it worked perfectly). Then I decided to get fancy and installed 10.10 to a flash drive directly from a live cd. I attempted to boot from the flash drive, and got a black screen with a blinking underscore for about 10 minutes, then I forcefully rebooted. Now, whenever I attempt to boot at all from my main HD I get "error: no such device and a ton of misc numbers. And the flash drive will not allow me to boot from it. Currently, I'm working within the Live CD.
I have a few projects I need to complete with Dreamweaver inside XP, so recovering it completely would be nice.

I set up my Dell Inspiron Laptop as Dual Boot -> Xp / Ubuntu 10.04. - all worked well. I had 2 installations of XP on this machine and I removed one - all worked well. I then went into XP and deleted the partion (4) that the old XP had resided on (using Easeus Partition Master) All NOT working well !! Now when booting the machine I get grub rescue> I did ls and got ....
I was dual-booting XP and Ubuntu 10.10 for a while, but as I never used Ubuntu it was just taking up space, so I figured I'd get rid of it. I used a partitioning tool from inside XP to remove the Ubuntu partition, forgetting that I used GRUB2 every time I booted to select which OS to load. Now when I start my computer I get stuck at the "grub rescue>" screen.After searching for solutions to this problem all of them said to either use the Windows XP CD to fix the Master Boot Record or reinstall Ubuntu, but I dont have my XP CD and there isnt enough room on my hard drive anymore for a Ubuntu install. Is there anything else I can do to fix this?
I'm experimenting a bit with my fedora, so I need to enter rescue mode very often. Every time I want to enter rescue mode, I need to insert fedora DVD Is there a way to install rescue mode on my hard drive so I could boot into rescue mode from GRUB?
