I accidently deleted my ubuntu partition, and when boot I get this message:GRUB loading.error:unknown filesystemgrub rescue>I can't get into my bios options either... I just see the MSI splash screen and it cuts right to this error message.
View 4 RepliesI 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 am fresh to Ubuntu and am having trouble getting it to boot on my system. I normally run XP, but recently added a second internal hard drive and installed Ubuntu on it. The installation went fine and upon initial reboot I received -
GRUB loading. error: no such disk grub rescue>
I am wondering if there is an issue between two different operating systems upon boot. I am not familiar with GRUB commands.
Downloaded Ubuntu 10.04.1 Desktop AMD64, tried to install it to a cleand HDD using the whole HDD, i.e. gave it permission to use the whole HDD. Installation process appeared to run OK but when it came to the restart it just fired up the message
error: out of disk
grub rescue>
I've searched this forum and found numerous references to these error messages but cannot make head nor tail of the diagnostic suggestions. Apart from anything else they suggest strings of command lines which I don't understand and can't enter anyway since they don't correspond to my keyboard layout (if I hit > or ) something completely different appears on the screen). Is there someone here who can provide a step-by-step solution in lay language ? Or is there such a thing as a bootable file which can be downloaded and inserted into my CD drive to correct this problem ?
I am running a 14 disk RAID 6 on mdadm behind 2 LSI SAS2008's in JBOD mode (no HW raid) on Debian 7 in BIOS legacy mode.
Grub2 is dropping to a rescue shell complaining that "no such device" exists for "mduuid/b1c40379914e5d18dddb893b4dc5a28f".

The UUID for md0 is `2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` so I do not understand why grub insists on looking for `b1c40379914e5d18dddb893b4dc5a28f`.
**Here is the output from `bootinfoscript` 0.61. This contains alot of detailed information, and I couldn't find anything wrong with any of it: [URL] .....
During the grub rescue an `ls` shows the member disks and also shows `(md/0)` but if I try an `ls (md/0)` I get an unknown disk error. Trying an `ls` on any member device results in unknown filesystem. The filesystem on the md0 is XFS, and I assume the unknown filesystem is normal if its trying to read an individual disk instead of md0.
I have come close to losing my mind over this, I've tried uninstalling and reinstalling grub numerous times, `update-initramfs -u -k all` numerous times, `update-grub` numerous times, `grub-install` numerous times to all member disks without error, etc.
I even tried manually editing `grub.cfg` to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `(md/0)` and then re-install grub, but the exact same error of no such device mduuid/b1c40379914e5d18dddb893b4dc5a28f still happened.
[URL] ....
One thing I noticed is it is only showing half the disks. I am not sure if this matters or is important or not, but one theory would be because there are two LSI cards physically in the machine.
This last screenshot was shown after I specifically altered grub.cfg to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `mduuid/2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` and then re-ran grub-install on all member drives. Where it is getting this old b1c* address I have no clue.
I even tried installing a SATA drive on /dev/sda, outside of the array, and installing grub on it and booting from it. Still, same identical error.
I have tried to follow the different possibilites discussed here [URL]
But I am not getting anywhere.
Btw, this is not my screenshot. Mine shows GNU GRUB version 1.98-1ubuntu5.
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".
got four partitions, one for media storage, one with ubuntu 9.10 32bit, one with crunchbang lite 9.04 64bit and one swap partition. The partition with ubuntu has been formated from ext4 to fat32 (with nothing on it, obviously). Whenever I boot up the pc now, I get an "unknown filesystem" error and a grub rescue> prompt. When I try to boot up a live usb image from my usb stick I either get a "linux kernel not found" message (crunchbang lite 32bit) or "initial menu has no LABEL entries!" error (gparted live usb) which changes to "Could not find kernel image: vesamenu.c32" after a couple of seconds. save my media partition or, more importantly, my crunchbang lite partition (which has one single important file on it, I'd love to recover). If this is somehow not possible, then I'd at least like to get my system usable again by succesfully booting from usb. I'm fairly new to using linux. I tried some grub-rescue commands, but not even the "help" command worked,
View 2 Replies View RelatedRecently 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.

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.
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:

converting from ubuntuinstall went okay but upon reboot I get: grub rescue > ls => (hd0) (hd0,1) ....root (fd0) => unknown command root
View 2 Replies View RelatedDeleted 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>
View 9 Replies View RelatedI 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

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.
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.
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.
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.

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.
