Ubuntu Installation :: Grub Rescue Won't Read From USB
Mar 19, 2011
I've tried reading other threads about grub rescue but it seems like it only works if the USB stick can actually be read. Sorry if I sound dumb, I'm really new to all of this.I installed Jolicloud (it's based off Ubuntu, apparently) to dual boot with Windows 7 which I got with my netbook. When I tried to get rid of Jolicloud, I think I accidentally deleted a partition-- now whenever I boot up my netbook, I get the black "grub rescue" screen of death.
I tried getting the netbook to boot from my USB but it won't do it. The USB light flashes but nothing happens. I know there's things in there because I can boot from the USB using my desktop. Jolicloud was initially installed from the USB so I don't know why it won't read it anymore.
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:
Upgraded from Ubuntu 9.04 to 9.10 via upgrade manager System is AMD 64 Have dual boot with XP on seperate hard drive
[code]....
Then the wheelspin:
Seem to have knocked out GRUB as normal loading screen does not appear anymore. Worse, I think I accidently installed grub to something labelled SDC5.
Cannot get anything except the "grub rescue" prompt. I'm not sure if using the LiveCD (9.10) can help. Have tried a few prompts from other threads but just ended up with mud splattered all over the place. I'm gathering I need to load grub, but can I do it using any grub rescue commands?
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.
The day that the upgrade came out (not beta, the true release) I upgraded via the Update Manager. The upgrade went great until it asked me to reset to finalize. Upon doing that, I was greeted with a less than friendly grub-rescue> screen. The materials I currently have at my disposal are a 10.10 installation disc, and an 8.04 installation disc, and a rescatux disc (super grub) that seems to yield an error upon any of the four options presented... how can I use these (both have Live CD) to fix the grub...
I installed Fedora on my pc over Ubuntu and now Grub wont go any further than rescue mode. (Apparently grubs boot folder was on the Ubuntu partition. Now I see why a dedicated boot partition is handy.) I used VMware to install Fedora as im currently out of CDs. VMware is setup to use the Physical HDD for the primary HDD in the VM. (I made sure VMware disabled access to the windows partitions so the guest couldn't access them.)
I am in Windows 7 at the moment and am avoiding rebooting as that will basically lock me out of the only computer I have access to. I tried running the Ubuntu LiveCD to restore grub but dont know how to mount Fedoras LVM partitions. What can I do to repair grub or at least install an MBR that is capable of booting windows? I can boot floppies and cds using VMware but am not sure what to use to fix this.
Fedora LiveCD wont mount any of the partitions to install Grub Ubuntu LiveCD may work if I can mount the LVM partitions.
I have windows 7 64bit on an internal harddrive, a larger internal harddrive for storage and a 1tb mybook external for storage. I have an ubuntu 9.10 iso burned to a cd that i got from the ubuntu site and I had previously installed dual boot successfully on my other computer, a laptop.
I went to install it on my desktop as well and when i was selecting how much space to allocate i noticed it was using the mybook and not the internal. I couldn't see an option to change which harddrive it used so in my ignorance i allocated 50gigs to ubuntu on my 1tb external mybook. This was obviously the wrong decision as after restarting the grub bootloader would not open and grub rescue came up everytime after that.
I have tried booting from the cd, reinstalling from the cd, and using a windows 7 repair cd. I can't even get into non installed version of ubuntu to try and use terminal. I have spent the 5 hours on the internet trying to figure out what to do and i have no clue. I want to get ubuntu off the mybook and get back on windows 7 where i can then reinstall ubuntu properly on one of my internal harddrives.
I just (for the first time ever) installed a version of Ubuntu. It is 10.04. I installed off of the Live Disk. I was having a great time until the first time I went to boot into it and I got the message "Error: No such device: "long number" Grub Rescue> "
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 had windows XP and Ubuntu installed on my Asus 1000HE and the hard drive is failing so I need to RMA it. They told me to restore it to factory defaults which I just press F9 at boot 3 time and Ghost takes over and reformats, creates 2 partitions and installs XP on one of the and the other is for another OS or just storage if needed.
I did that now I get a grub rescue prompt when I boot my netbook. Is there a way that grub installed itself to my PE partition that's a hidden partition that came with the netbook? I've taken the drive out of the netbook and put it into my desktop and formatted both main partitions but not the restore one. Yet I still get the grub rescue prompt, how can that be?? I can't even boot from flash drive or get to bios it just goes straight to the rescue.I need to send the netbook back but can't unless its restored. Right now I'm on the 9.10 live flash drive I made on my desktop and my only hard drive attached it the netbooks.
I tampered with installation process while I was reinstalling ubuntu, now I have this command on my screen and I'm stuck. GRUB RESCUE>_ What do I need to type, to continue installation.
I have tried to upgrade to 10.4 LTS it crashed I use dual booting whenever I try to start the computer it goes in to grub rescue > I have used wubi to install the dul booting, now I can not get into my window nor ubuntu. what can I do ?
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 have ubuntu in sda7. sda6 had bt4, sda3 had Win7. From Win7 I removed sda6. Now when I start my computer I get grub rescue. How can I tell grub that ubuntu in sda6 and not in sda7 anymore or how can I create sda6 again so ubuntu goes sda7.
-Ran Windows XP Media Center for most of the life of this HP Pavilion notebook with 2 hard drives, C: and D:, no partitions except the default HP recovery partition
-Yesterday, installed Ubuntu 9.10 through Wubi on D: from an ISO (because the CD drive doesn't work). I assigned it 30gb on D:, which I assume created a 30gb FAT32 partition on this secondary drive.
-Dual booted successfully from Grub between XP and Ubuntu, so I thought, "Mission accomplished" and started making friends with GNOME. Got a pretty good score in Tetris.
-Was asked if I would like to update to the latest Ubuntu (10.04 I think?) which struck me as a good idea. Everything went smoothly until it asked me to reboot.
-Reboot brought me to a command-line that says "grub rescue>" and above it says "error: no such device: e76e00f3-........" (there's more, I can write it out if that helps)
-Rebooted several more times (cause that usually fixes things) but just got back to "error: no such device: ..." and "grub rescue>"
And that's where I am now. I have almost no experience with how Linux (UNIX?) works differently than Windows or how to use the command line. I know that the hard drives are (hd0), (hd1) instead of C: and D: and that everything important seems to start with "sudo" and that's about it. I was going to ease myself into the whole thing gradually, picking up little bits as I go along. But now I'm just stuck in command line limbo and none of my usual troubleshooting strategies apply here, not even yelling rude things about the computer's manufacturer.
I am reading spc456's thread with the same subject line and trying to work through the thread with suggestions by drs305.
My situation is very similar. It started with a sudden Windows boot problem (still my primary OS):
Quote:
This was only if I selected Windows from the boot menu. I thought I could cure it with the Windows-7 Repair Disk from neosmart.net. This appears to have wiped my Boot partition completely and now I can't boot anything. (I'm using the Ubuntu 10.10 live as I type this.)
I downloaded boot_info_script055.sh and here are the RESULTS but I don't know what needle to look for in that haystack.
Code:
Boot Info Summary:
Well, I see why the Windows boot didn't show up. Looks like 30-OS_prober was failing to find the Windows boot record, which makes sense if the whole blessed (ahem) boot partition has been hosed.
I tried to follow the grub-install instructions:
Code:
But since grub2 is obviously not going to find the Windows boot record, I will continue with drs305's.
Code:
No, I have not mounted /dev. Where would I do that? Against which FS?
In any case, I am now printing the article "How to restore the Ubuntu/XP/Vista/7 bootloader" to see if I can get that going.
To my dismay, I discovered that the disk supplied with my Dell machine is NOT a Windows Installation disk, so no straightforward "fixmbr" command will be possible at this time.
I'll let y'all know how I have fared with this. I am sceptical because it's not merely the master boot record that has gotten corrupted but the whole blessed (have I used that adjective already?) boot partition.
Trying to do a new install of ubuntu 10.10 to my laptop. Installation and all works fine, but upon rebooting, after the bios screen i get:
Code: error: out of disk. grub rescue> I tried using following some instructions i found after googling for the problem: Code: ls (displays the partitions and devices Grub can see) set prefix=(hdX,Y)/boot/grub
[Code]...
but after the 5th step, i get another "error: out of disk" message. The odd thing is that I had an install of 10.10 on this laptop a month ago, and it worked fine. As a side note, I installed fedora 14 after this happened, which worked fine. Reinstalled ubuntu, and it was back to the same problem. I also tried installing with a kubuntu cd I had, to make sure it wasnt the install media, and had the same problem.
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 am new to ubuntu OS, I am having quiet a hard time solving out certain problems. I have Ubuntu 10.10 and Win Xp installed on the same hard drive partition i.e. C drive. Now yesterday accidentally I deleted a folder from C while I was logged in to Windows. Now today when I restarted my pc I got this error message : error : No partition found grub rescue>
Then somehow I managed to reinstall the Grub loader. Now whenever I restart my PC I get this error message : GNU GRUB version 1.98+20100804-5ubuntu3 Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. grub>
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.
I just installed Ubuntu on a separate hard drive alongside Vista, and after restarting, my computer booted to a screen that said, "error: no such device: xxxxx-xxxx-xxxxx-xxxx (I don't remember exact number, if I need them I'll go back and write em down) grub rescue>"
After a bit of searching I found this thread: [URL].. I tried the first part twice which didn't change anything, so I tried the last part which was too fix the vista bootloader, which worked perfectly, and now I can get into at least one operating system. Would anyone please help me get a bootloader working so I can choose between Ubuntu and Vista? Also, is it worth mentioning that right before the computer shut down after installation, I had a huge list of I/O errors?
EDIT: After further searching I read that the I/O errors were commonly because of a faulty cd or it was spinning too fast. I think my problem with that was that it was spinning too fast, it was incredible loud and there was a huge amount of wind coming out of my computer XD. iirc I have to go to the BIOS to change disc speed?
EDIT2: I think all my problems stem from a faulty CD. I remember setting the burning speed too the highest setting when I burnt the live CD, I guess I thought faster was better.
i just installed ubuntu 10.10 x64 on my computer and removed the windows 7 partition and installed it on that one it installed as usual now as i booted it give me the following error
Code: error:no such partition grub rescue> i tried one or too methods given to restore grub but it isnt working wht can be done ?
I installed ubuntu 11.04 on a usb hard drive which I created a 100 gig partition however when i try to boot from the usb drive I get the message error:no such partition grub rescue> when I boot from live dvd I can see the partition I created with all the files on it.
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.
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.
I had a nicely working karmic 64bit/windows XP install, but the "upgrade" button to 10.04 has finally got the better of me. Now, when the PC boots up, the following failure occurs:Memory CheckPCI device listingVerifying DMI Pool Data ......error: no such device:e9eb88c2-67f2-47a7-bf9d-50b77b2d3480grub rescue>_Some more information.linux is on sdb1when I type "ls" I get: "(hd0) (hd1) (fd0)"however, I've not managed to get "ls (hd1,1)" or similar to do anything, the best I get is "error: no such partition".the command "find /boot/grub/grub.conf" results in the error "Unknown command 'find'"I've tried swapping the boot order in the bios from hd0 to hd1 but that has made no difference.There is no grub loader, no linux, no windows, no operating system of anykind, just the "grub rescue>" prompt.
After lots of searching last night I noticed that over the last couple of days there have been quite a few posts of people receiving the error: no such device lots of numbers grub rescue>. I have a dual boot vista/ubuntu setup with ubuntu on my d: drive and windows on my c: drive and it happened to me last night. So after my freaking out when I received the grub rescue> error after updating somethings in my ubuntu install and restarting. Once the computer rebooted bam! error. after much freaking it only fixed itself by reinstalling the windows bootloader via the vista rescue disk I was wondering if there was a way to prevent this from happening again? will ubuntu attempt to "update" itself again?
