Ubuntu :: Stuck At Grub Rescue And Can't Boot Fom Cd
Nov 26, 2010
I lost power during my Ubuntu update and when I powered back up ubuntu was broken. Now the stupid bit. My hdd was partitioned into 3 bits, vista os, data, and ubuntu. In vista I deleted the ubuntu part and merged it with the data part. Now when I power up my computer it goes straight to a black screen that says...
error : no such partition.
grub rescue> I have looked through the forums for an answer to my problem but to no avail. When I put the ubuntu live cd in and turn back on itjust goes to the same screen. I'm a novice to the world of computers and need any help you can offer.

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?

Deleted the Ubuntu partition by accident. Now at a loss as how to get Windows working again. I had all my files saved, and did a full format and reinstall to Windows. Thinking that it would just overwrite grub but this thing is like a virus.. I cant do **** at the grub rescure command prompt... it just sits there with a cursor... Even stuff like reboot and quit or exit don't even work... what the hell? So I pop my Win7 install cd in and I find that for some reason I have no recovery console... just the option to install. I install but no grub, the little virus is still there and I just wasted an hour of my life while Win7 installed again because I still cant view it.
I deleted all the partitions and wiped the entire disc and grub is still there.. I was thinking that Windows would just replace grub automatically. Heh the Bootsector always seems to get owned on Windows and I expected grub to be just as useless but in it's own way, it's worse.

I recently partitioned my hard drive so that I could have Linux in addition to Windows Seven on my laptop. For some reason, at boot it it showed not only Linux, a Recovery mode for Linux, and a Windows 7 OS, but also a Windows Vista OS that I never installed. Yesterday, A friend of mine borrowed my computer and chose to open Vista. Since then my computer has been stuck at the grub rescue screen with nothing other than the message: error: no such partition grub rescue>

I thought I'd have a go at putting back sysvinit to run the start up daemons, after I discovered that upgrading to jessie removed it and slapped on systemd.
I didn't have any problems at all with systemd, infact it was pure speed at start-up, but after some reading I thought I'd like to go back to usual start-up scripts.
What I did was to boot a Live Debian and mount and chroot into my Debian system, then I ran
Code: Select allsudo apt-get remove --purge --auto-remove systemd
sudo apt-get install sysvinit-core sysvinit sysvinit-utils
On reboot, I hit a grub rescue prompt which says error: file not found.
Trying the methods to get that sorted out gets stuck with "unknown file system" after I use ls and ls(hd1,msdos2) -as well as other combinations - it only seems to work for a plugged in flash drive.
Then I chroot again and run update-grub and grub-install /dev/sdb but reboot still stops at grub rescue.
So I wonder, firstly, why replacing systemd mucked up grub. Then, besides re-install of systemd, how do I get a booting system?

Dell Inspiron E1405 - 160 GB drive with 2 partitions - I think only 1 partition was used for windows and ubuntu Used wubi to install 10.04 - both XPP and 10.04 worked fine after repairing the XP install My boyfriend used Referencer (.reflib) in Ubuntu 10.04 to organize and tag about 900 documents. He spent around 9 hours on the project and its VERY IMPORTANT. I am a dumb ***, forgot the project was on the computer and updated to 10.10 via update manager without it backing up. Now I cant boot to XPP or Ubuntu - "error: no such device:", "grub rescue" My main concern is getting the data back. I would rather uninstall WUBI and install Ubuntu on the 2nd partition (wish I would have done this in the first place but 10.04 was my first Ubuntu install and I didn't know any better). I have to get this data back! I have tried the following and cant locate the referencer (.reflib) file or the .docs and .jpgs booted to USB using my 10.10 netbook remix USB install USB stick - I can see the windows files pulled the HD out and connected it to my Ubuntu netbook, an XPH and W7 computers -cant locate data

It happened when I updated my php5.4 to 5.5 version on my small Debian 7 server. I am only getting GRUB right after BIOS boot pass, then none of the keys working even C or Shift buttons to go to command promt except CTRL+ALT+DEL.
I have tried rescue mode with live CD, selected myserver/root/ partition to install GRUB but not worked.
How to recover my server, I have some important data in it and I don`t want to destroy them.

my computer is currently stuck in "Grub Rescue mode" I don't know how to get it unlocked. I tried installing the latest ubuntu from wubi after I deleted the partition for 11.04 beta I had already had (I had some issues with 11.04 so I went to windows (it's a dual boot machine) and cleared the partition) After I got rid of ubuntu from there I don't think it automaticlly got rid of grub, which I was unaware of. So I continued to go through Wubi for to install 11.04 side by side Windows and to be used with the windows loader.
After I got thorugh all of that stuff I was instructed to restart my computer (as usual) and I did. But as soon as my computer came back on it came into "grub rescue>" with the error message at the very top of the screen "error: no such partition." I am currently using a different PC to type this. I would like to know how to get out of the rescue loader and at least back into windows (I have windows 7). I don't care to much if I can make it into Ubuntu as I have most of my more important files on Windows. I'm kinda scared atm, because I read somewhere earlier that I can't really do anything unless I have the windows boot disc, which I don't.

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'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.

Yesterday I made a thread about going back to Windows as I'm giving this laptop to a friend. Anyway, after I finally got Windows to re-install I'm now stuck with "grub rescue" instead of the OS booting. Is there anyone who knows a way I can get rid of grub rescue and get Windows to boot?

I installed Ubuntu server with software raid 5 and all went well. Then I figured I should test the raid by these instructions [URL] As a result mdadm would create /dev/md0 with 3 drives and 1 spare. Confused on this matter I just reinstalled Ubuntu. Now, I'm greeted with a grub rescue prompt at boot. Running set displays the correct parameters and ls (md0)/ shows the content of /. However, ls (md0)/boot/ shows no content what-so-ever. If I boot from the livecd there are all the files needed in /boot. I've tried running grub-install on all the drives without results.

Month or so ago I ran into BusyBox, so while reinstalling Ubuntu 10.04 onto to that first FreeBox HD from a live CD, while manually adding & editing a new partition with free space to put Ubuntu into, I must have accidentally edited pre-existing partitions possibly deleting everything off of that HD. After reinstalling, I went into the terminal & ended up trying to recover or restore the partitions that I thought were lost or deleted or struck sick (since it had BusyBox). But that broke it. Now, after breaking that first HD of mine, when booting, I run into the following at startup:
error: no such partition.
grub rescue>
Right now, I have that first HD as my slave HD I can no longer find this HD, I can't load into it. It might have died because it was making noises the last several weeks. But just yesterday when trying to get into this same first HD from Ubuntu, I'd receive this message:
Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

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?
My desktop has been down for more that two weeks
Ubuntu version: 10.04

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 cant boot from my External HD with ubuntu installed.
I get this message:
error: file not found. grub rescue>
In an attempt to fix this problem, I tried using the following sudo command:
sudo mount /dev/sda5 /mnt
sda5 does not exist, I tried 4, then 3, then 2, and it worked, but that was a partition of my internal HD containing windows 7.
I also typed in:
sudo grub-install --root directory=/mnt /dev/sda
not I get the following error when I try to boot from my internal HD:
error: no such device: 57288a24-5d12-4fb1-b27e-eb09a1f9b7c6. grub rescue>
Is there a way to get grub to boot into windows 7 again?
When I type:
sudo fdisk -l
I receive a list of my drives and their partitions, This is my assumption as to what drive is
Which:
/dev/sda1 = Vista loader, for Windows 7
/dev/sda2 = Windows 7 (At least I hope its still there.)
/dev/sdb1 = Bootable Flash Drive.
/dev/sdc1 = External HD.
The text from the terminal is as follows:
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x8da4c52c

/dev/sda1, 1, 1355, 10877952, 27, Unknown.
/dev/sda2 *, , 1355, 38914, 301961224, 7, HPFS/NTFS. (The commands changed this from FAT32)
Disk /dev/sda: 8054 MB, 8054636032 bytes

Device, Boot, Start, End, Blocks, Id, System.
/dev/sdc1, *, 1, 30402, 244197376, 83, Linux.
Eventually I would like to fix the error I get when I boot from the external, I would like to to boot to ubuntu, but for now I am concerned with getting my internal HD to boot windows 7. Where I originally found the terminal commands to begin with. I think sda5 is where linux was installed in the example I found, and didn't realize it.

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 grub 1.98 and it boots fine with out my usb hdd connected but brings me to grub rescue when it is.
It takes me to grub rescue and tells me that it cannot find device: "UUID"
This UUID is not even the UUID of the drive that I cannot plug in if I want my computer to boot to grub.
Here is blkid with the usd hdd plugged in after boot:
Code:
/dev/sda1: LABEL="System Reserved" UUID="BA56FD4B56FD0941" TYPE="ntfs"
/dev/sda2: UUID="E23E02D93E02A71F" TYPE="ntfs"
/dev/sda3: UUID="9579da2d-5ba0-407c-a95d-9f134a1417f3" TYPE="ext4"
/dev/sda5: UUID="caefabd7-c8f0-4fca-8005-d682ae939b91" TYPE="swap"

I installed Linux and used it for a bit, then decided it wasn't for me. I installed it alongside Windows 7. Whence I decided it wasn't for me, I decided to get clever and delete the linux partition... Four hours later and I am still stuck where the grub comes up at computer launch and says "no such disks" then, "grub rescue>". I tried everything on the Windows 7 forums, tried overwriting the grub with a windows 7 disk. This thing still comes up everytime... grub rescue. how to overwrite this grub thing?

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.
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/sdf

I have a netbook that dual-boots Win XP and Ubuntu 10.04 and accidentally hit the Win recovery mode in GRUB today, but quickly restarted without formatting or proceeding with any recovery. But upon reboot I just see: error: no such partition. grub rescue>
What I have tried so far: Boot to USB Live Disk... It won't, just goes straight to grub rescue.I do ls and it gives me (hd0) (hd0,4) (hd0,3) (hd0,2) (hd0,1) (fd0) error: fd0 cannot get C/H/S values.
set gives me
prefix=(hd0,5)/boot/grub
root=hd0,5
but if I try to boot it says unknown command so I figured I needed to find the right partition to boot from but I went through all of them with ls (hd0,4)/boot, ls (hd0,3)/boot etc. and every partition comes back "unknown filesystem".
