Debian :: System Doesn't Boot Anymore - Grub Rescue

Feb 18, 2012

My system doesn't boot anymore, when I turn on the laptop, instead of the normal grub screen, i get the following:

"error: file not found
Entering rescue mode...
grub rescue> _"

I tried also to make a bootable usb w/ unetbootin but all the distros failed to load w/ a syslinux boot error message so I really need to fix the existing debian installation to get access to my files i need for the university, it's debian stable (6.0.4) on hp mini 210 ....

Ubuntu Installation :: Initial Boot On System - GRUB Rescue - Error: No Such Disk

Feb 11, 2010

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.

Ubuntu / Apple :: �error: Unknown File System Grub Rescue>� On Boot?

Apr 15, 2011

I previously had Ubuntu installed on my MBR. I deleted that partition (32 GB), resized my Mac partition back up to (250 GB), and then reduced it to 200 GB and created a new one with 50 GB via BootCamp to install Windows 7 from a DVD that I burnt (I got a Windows executable from MSDNAA that I used with Wine to obtain the ISO image. Insert rant about having to download Windows with a Windows executable here.).

I've tried burning two different DVDs. I used Burn on my Mac to burn a data DVD+R with the HFS+ and Joliet filesystems (I think) and then tried again with the ISO9660 and UDF filesystems. The latter has not shown any signs of working besides mounting on OS X. The first DVD would not boot whenever I held 'C' down at time of boot. So I went into BootCamp and clicked "Start Installation". It restarted my computer and this is where the real confusion comes up. I think that it tried booting via the empty partition. The reason I say this is that there are remnants of GRUB and when I boot, I get a screen that says this: error: unknown filesystemrub rescue>

Debian :: System Stuck On GRUB Message And Rescue Mode Not Worked

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.

Debian Installation :: Dual-boot Grub Rescue Says No Such Device

Feb 13, 2015

I'm inexperienced in Debian. I have a dual-boot machine (64-bit, Debian 7.3, Windows 7, legacy boot) and encouter a problem at boot ever since I completed the installation of Debian 7.3 alongside the exising Windows 7. This machine has six hard drives: two are intended for ntfs storage of general data (raided together by RAID1); two more are intended for ext4 storage of general data (also raided together by RAID1); the fifth contains the Windows OS files and the sixth contains the Debian OS files. The problem is that I arrive to the grub_rescue each time at boot, seeing the message:

GRUB loading.
Welcome to GRUB!

error: no such device: e081517b-3399-4067-9294-8f0686f753ca.

Debian Installation :: Grub Rescue - Will Not Boot From Mdadm RAID - No Such Disk

Sep 19, 2014

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".

Output from mdadm:
Code: Select all    # mdadm -D /dev/md0
    /dev/md0:
            Version : 1.2
      Creation Time : Wed Nov  7 17:06:02 2012
         Raid Level : raid6
         Array Size : 35160446976 (33531.62 GiB 36004.30 GB)
      Used Dev Size : 2930037248 (2794.30 GiB 3000.36 GB)
       Raid Devices : 14

[Code] ....

Output from blkid:
Code: Select all    # blkid
    /dev/md0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
    /dev/md/0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
    /dev/sdd2: UUID="b1c40379-914e-5d18-dddb-893b4dc5a28f" UUID_SUB="09a00673-c9c1-dc15-b792-f0226016a8a6" LABEL="media:0" TYPE="linux_raid_member"

[Code] ....

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.

When I try a grub-install it gives this error message:

Ubuntu :: Grub Doesn't Work Anymore Since Update

Oct 25, 2010

I've got a double boot system (Windows XP Pro and Ubuntu Maverick). Since I updated Grub2, Grub doesn't work anymore! I'd tried this (because I HAD that error). But since than, I'd a black screen (harddisk didn't anything, and Grub too...) And now, after using a couple of these commands via the Ubuntu Lucid Lynx Live CD I get a mini bash in Grub, but no entry's to one of the two systems! What's wrong, and what do I have to do? (and what did I wrong?

Ubuntu :: Invalid File System - Grub Rescue

Jan 1, 2011

I've (attempted) to create a quad-boot on my MacBook Pro (if the specs are needed, its- 8gbs RAM, core i7, 500GB hard drive @ 7200 rpms, and its running the latest update of snow leopard). I have installed rEFIt and had installed Windows 7 as well as ubuntu 10.10. Everything was working great until I tried loading Linux Mint 10. Linux Mint got rid of Ubuntu in the rEFIt boot menu. I thought the added Linux Mint partition had just pushed out Ubuntu, so I deleted the Linux Mint partition, and re-sized the Macintosh HD. Now whenever I try to boot Windows 7 or Ubuntu, I get something along the lines of "invalid file system: Grub rescue" What do I do?

Debian :: Grub Boot Loader On A Dual Boot System?

Dec 16, 2010

This is the third time I try unsuccessfully to install Debian as a second OS on a hard drive. When it gets to the end of the installation process the installer asks whether I want to go ahead with the Grub Boot Loader, I choose yes. The end result is however that I can't boot that partition within the hard drive -- i.e., Debian. Can someone tell me what is going on? Should I not use the Grub Boot Loader when I have more than one operating system on a machine? Should I not install Grub on the Master Boot Record (MBR)?

Ubuntu :: Windows Doesn't Boot Anymore / What To Do?

May 18, 2010

I have dual boot Windows XP pro SP3 / Ubuntu 9.04 and I only use the Windows to download torrents because the download speed on Ubuntu is terrible...
But by accident I pressed the power button when I was downloading in Windows and since then Windows won't boot anymore. Is this a Windows problem or is it maybe that it srewed up my grub? Because I can still select Windows in the grub menu but it stops at "Starting up".

Ubuntu Installation :: How To Boot From 'grub Rescue'

Jun 5, 2010

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.

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...

Ubuntu :: Grub Rescue > No Content In /boot

Feb 20, 2011

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.

Hardware :: Grub Rescue - Why Can't Boot Up Into Ubuntu

Apr 21, 2011

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

Ubuntu :: Boot Screen Doesn't Appear Anymore / Show That?

May 7, 2011

I'm fairly new to Ubuntu and I like it a lot. However, there's a graphical error which started to happen after the very first bootup. The startup screen (the purple one with the 5 dots that appear) isn't showing anymore. It is replaced by some console technical guff scrolling down my screen (which isn't a problem, because Ubuntu itself works fine, but it just looks a bit rough). Again, on shutdown, it displays some amalgamated mix of more technical jargon, and a terribly lo-res version of the shutdown screen.
Is there any way I can fix this?

Ubuntu :: Boot Windows From Grub Rescue Prompt?

May 13, 2010

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
