Ubuntu :: Partition Not Found Grub Rescue
Dec 3, 2010
I uninstalled ubuntu from my main HDD, and its now on a different HDD. when I turn on my computer I get:
Partition not found
Grub Rescue
I've used my windows disk and repaired my mbr and boot (bootrec /fixmbr bootrec /fix mbr) multiple times, yet I always get this problem.
Only way I can boot windows is if I leave my install disk in my drive. It will say press any key to boot from cd / dvd I just wait a couple seconds, and it boots into windows. Without the disk, I get the grub problem. I have only 1 partition on my HDD, and that is my windows 7 partition, nothing else.

A friend gave me Ubuntu 9-10 and I have been using it in my netbook for some time. Bthe other day we did an update and now a black screen is up and states: Error: no such partition Grub rescue>_ I am operating dual O'S with Windows XP and Ubuntu The only thing I have been able to do after searching hours on the Internet is the following: When I type set it gives me the following information:
Prefix=(hd0,5)/boot/grub
Root=hd0,5
Grub rescue>_
I understand that the hard drive is 0 meaning the only one I have and 5 means the location of the grub in the partition. Other than that I can get no further!

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.

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.

I have been using various versions of Ubuntu for many years. I love it and I want to stay with it. Now I need help more than ever. So basicly I've searched through forums and other sites which seem to have had the same problem I am having.
However, I've tried all the "fixes" and nothing works at all at this point.
Here is what I have tried so far: [url] and every suggestion here: [url]
When I put in "sudo fdisk -l" I get this:
So after trying the suggestions in the above links I would restart and still get: "error: file not found. Grub rescue>"
I am trying to install it from a usb to an external hd. I installed Ubuntu 8.4 on the same hd before and it worked fine however I need one of the newer versions to use the programs I need. I've been at this for hours and maybe I am just missing something simple.

I have two partitions installed on my computer, Ubuntu 10.04 (part. sda2) and Windows XP (part. sda1). When I restart my computer I get this message:
error: file not found
grub rescue>
I thought this must be a grub error, so I booteda Super Grub disk (v 0.9799). Then I tried to fix grub with the Super Grub disk, but I got this message:
Error 15: File not found
Booting 'not lucky'
pause SGD has NOT succeeded
SGD has NOT succeeded
I then booted the system using an Ubuntu live CD, version 10.04.I tried to repair the sda2 Ubuntu partition. At a terminal prompt I ran [code] sudo e2fsck -f -y -v /dev/sda2. This did not work. It ended with "e2fsck aborted". I could not repair the Ubuntu partition,
I tried to open the sda2 partition by running the terminal command [code] sudo mount /dev/sda2 /mnt. I received the following message:
mount: wrong fs type, bad option, bad superblock on /dev/sda2
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Using the ntfs-config program, I can easily mount the Windows XP partition (sda1). It mounts and I can read or write the files on the Windows XP partition. So at least Windows XP is not damaged. I downloaded and ran the boot info script, and here are the results:
Code:
Boot Info Script 0.55 dated February 15th, 2010
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #2 for /boot/grub .....

I own a Sony Vaio VPCEB3AFM. It came with pre-installed Windows 7 Home Premium 64bit, no disks or anything. The product key is on the back of the laptop. I later installed Ubuntu, as I was beginning to take an interest in the potential of computers and began to explore with different Operating Systems. I installed it along side Windows 7. THEN, me being the dumbass I am, installed BackTrack 5 also. I then called Sony in attempt to restore my computer to factory defaults and just have Windows 7 as my only operating system. I shut my computer down and then hit F10 until the Vaio Rescue shows up. It was in the process of Restoring when it restarted and an error message came up. It reads, Error: No Such Partition Grub Rescue>. I have no idea what to do none of the OS boot up when I start it. I have no disks, I have only Ubuntu on a USB drive which I boot up by changing the BIOS blah blah. But when I do not have it in, the error message occurs.

I know this is a common error, but my situation is a little different than previous threads on this issue and I just want to make sure I get the correct solution.
Basically, I had Ubuntu 10.04 and Windows 7 on my netbook and wanted to try a more lightweight version of Ubuntu. After settling on LXDE for a desktop, I decided to install Lubuntu 10.04. I chose not to install LXDE over regular Ubuntu because I wanted to eventually end up with an Ubuntu distro with either GNOME or LXDE, but not both. So rather than put myself through the hassle of uninstalling all the GNOME or LXDE packages, I decided to keep them each on separate partitions.
In the end I decided to just stick with regular Ubuntu and deleted the Lubuntu partitions. Now I get the GRUB error written in the title of this thread.

I running a dual boot of 10.4 and windows 7 and was trying to add a free disc space to one of the partitions using gparted and the window 7 tool. On restart I get this DOS-like message:
Code:
Error: file not found.
grub rescue>
From what I have gathered, from other posts I should
1. Go here [URL]
2. Reboot and run ubuntu from the live CD
3. Create a results.txt file
Here is the results data:
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 #5 for /boot/grub.
=> No boot loader is installed in the MBR of /dev/sdc .....

I have a new installation. I try to boot and instead of my grub menu, I get "error: file not found" and am dropped into the rescue prompt. I have just a standard "Desktop" installation. I installed from the 5.05 net install cd. I installed grub to the MBR.
partitions are:
hd0,2 is /
hd0,5 is swap
entering the "set" command results in:
prefix=(hd0,2)/boot/grub
root=hd0,2

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.

I have a major problem with Windows 7's MBR. I deleted Ubuntu's partition last night, and when I restarted, I saw:
Code:
error: no such partition
grub rescue>
I looked it up, put some code into a LiveCD terminal, and I thought it worked. But now, I says that I definitely need to put in a Windows 7 CD and do that MBR fix method. I did not own a Windows 7 CD; my laptop came with it pre-installed, and I have no recovery partition anymore.

I had 3 partitions on my hard dive, Windows 7, Ubuntu, and just junk on the other. I installed Ubuntu in a way where it went to the GRUB filesystem? first, where it ask me to start in linux kernel 2.38.6 (can't really remember the kernel exact name) which was ubuntu, some other options, recovery mode, and at the very bottom was the one to go to Windows 7. I was in Windows and I wanted to get rid of my junk partition but I formatted the Ubuntu partition by mistake.
Now when it boots up it saying:
Error: unknown filesystem. grub rescue>
I hope there is a way to save my files on Windows. I tried to reinstall Windows 7 back on my computer but it wouldn't go through since the grub startup thing is the main one, not the windows one.

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".

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>

Windows 7 x64 was the only install with a separate boot partition which was already on the Dell laptop. I then shrunk the partition to allow me to put opensuse on. Then I made the stupid mistake of deleting the opensuse and boot partitions while in Windows. I was going to do this, copy pictures of my new born baby off then reboot and delete all stuff and redo all the partitions and installs again.Now I just get grub rescue with the following when I do ls command:(hd0) (hd0,1) (hd0,2)I would like advise on how to get the data off, I cannot afford to lose my babies pics as there are no other copies. I will then do a normal install of opensuse first then Windows 7 after it.

I am to reinstall the notebook of my father, that had Windows XP and Ubuntu on it. And I dont know anything on Ubuntu. My objective was to make a fresh install with XP only.So I was checking the partitions within Windows and found 7 or 8 of them which I could not understand: I asked to remove them, one by one, and got some error mesage on Windows. Now I understand these were probably used by Ubuntu.Now, when I restarted the PC,n I got:"error no such partition grub rescue"..I tried to boot from the CD - a windows XP setup CD, but I get blocked as well, because when I try formatting the drive during the installation CD it makes an error, or otherwise without formatting I also get an error.I guess the partitionning information of the hard drive is inconsistent, making everything fail.I dont know what to do.I am thinking to use a USB disk to reformat the HD, but I am not sure it will help.

Just delete a linux partition and now when i boot a message appears and says error: unknown filesystem grub rescue >
I have search on the net for this problem and i have understand it a little. But my situation is a bit different and because i don't want to format my hard disc i wanna try to fix it. So before a couple months i download ubuntu 9.10 and i installed it a month later. But my computer used to crash all the time and i couldnt use it. So i download the latest ubuntu 10.4 and install it while having windows xp and the old ubuntu 9.10(so i had windows xp, ubuntu 9.10 and ubuntu 10.4 partitions). Now i tried to delete the partition of ubuntu 9.10 from disc utility. so i have the message i wrote above when i boot. I dont wanna delete my windows xp and ubuntu 10.4. what should i do to stop this message from appearing.

Ubuntu 9.10 was set up to handle the booting selection - previously I thought it was xp but Ubuntu 9.10 "did" it. The system started out as a xp / ubuntu 9.10 dual boot on a 400gb drive. xp has 210gb, ub has 80 and their is a 100gb shared storage. Xp was installed first and then I followed a guide over at linuxconfig.org to get ub installed so that I could select which OS was wanted at boot. Ubuntu manages the boot up menu (Went back to look at my notes from the original setup) The owner tried to update to ub 11.04 and afterall was said and done the machine now boots to the message
error file not found grub rescue I can't say if 11.04 was properly installed or not. Ask whatever you like and I'll give the best answer I can. I think the xp install is okay but I can't say for certain as I don't know how to boot it outside the bootmanager at startup. Data has been saved so if I have to blow it all away and start over I can but I'm hoping I won't have to.
