I'm experimenting a bit with my fedora, so I need to enter rescue mode very often. Every time I want to enter rescue mode, I need to insert fedora DVD Is there a way to install rescue mode on my hard drive so I could boot into rescue mode from GRUB?
View 4 RepliesI 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:
[Code]....
Is it still possible to use LiveCD to boot into rescue mode and run fsck?
I just want to run fsck on my hard disk and make sure all is well.
Does fsck provide and logs or records of what it found?
Is it possible to run fsck without LiveCD?
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.
Today it happened again: After an apparently trivial update Grub (Grub2) enters rescue mode the next time booting, not displaying any useful help whatsoever at that point. (Remember that at boot time no manual or help pages are available.) I don't know what went wrong, but ... The harddisk or partition in question is now no longer a bootable partition.
I don't want to use much time trying to sort out things, so unless someone may direct me to at better procedure, I am going to save whatever can be saved from the hd and then reinstall debian (in this case: Sqeeze) from scratch. Nothing else has in my experience ever worked before.
I've got CentOS 6 installed and am wondering if it's necessary to have installation media in order to run 'linux rescue'. (I have to do some LVM resizing and would rather do it from rescue mode than in a running system.)
What I've read about booting into linux rescue is that it seems to be necessary to have installation media and boot into that. But I'm wondering if it's possible to do it some other way, like from the grub menu? But it doesn't seem to be possible to enter 'linux rescue' from the grub command line (which I got to by typing 'c' in grub menu screen) - typing 'linux rescue' at grub command line says 'command not found'.
Maybe there's another way to do this? Or some fancy way to have loaded a rescue image or something onto my disk so I don't need installation media. There's 2 reasons why I'd like to enter linux rescue without installation media, both because my computer is very old. 1) My computer can't boot from USB, and 2) My CD/DVD tray is very unstable and keeps popping out intermittently, so I'd need to hold the tray in place during the whole LVM process and it's a real pain, and I wouldn't want to risk data corruption if the process is interrupted by my CD/DVD tray popping out.
I'm hoping there's some way - it'd also be nice to know how to do this if some urgent situation arose where I needed to enter linux rescue mode but didn't have installation media handy and it'd take to long to retrieve or create new installation media.
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'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 have an Ubuntu 10.4 installation (dualboot with windows XP) with grub2.After I resized some of my partitions using a gparted live cd, the system goes directly to grub rescue mode every time I boot.Then I follow the instructions which are given in grub2 wiki site to boot.The grub boot directory is now located in sda6 (hd0,6) in my system as found out using 'ls' command.
But in the grub rescue mode when I enter the 'set' command (one of the very few commands available), to display current prefix and root, it gives "(hd0,7)/boot/grub" as 'prefix' and "hd0,7" as 'root'.After entering the following commands, I'm able to boot.There are other users at my home not familiar with ubuntu. windows is their OS of choice. So I don't want to remove windows installation .One solution that I can think of is creating a grub rescue CD using grub-mkrescue, then using windows cd to fix mbr (which will overwrite grub? or the pointer to grub?) and then using the grub rescue cd to boot into Ubuntu but I'm not sure.
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 got my wife to try Linux, so we set her machine up to dual boot with Windows. After a few weeks, she decided not to use Linux, so we deleted the Linux partitions using Gparted on a USB drive and resized the NTFS partition, under the apparently mistaken impression that Grub would detect that there was now no other operating system. When we rebooted, we got error: no such partition, followed by a grub rescue prompt. I've never worked with Grub directly before, so I have no idea what to do at this point.

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.

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?
View 5 Replies View RelatedI installed debian testing from hard disk using the netinst.iso. Now how can i get the rescue mode to reinstall grub? During installation i didn't get other options like rescue mode.It guided me to install debian testing from hard disk only.
View 2 Replies View RelatedBackground for the problem:
A. I have partitioned my WinXP LTop into:
--- WinXP NTFS partition
--- a vfat partition (mounted onto /fat32)
--- Installed F10 on ext3 virtual partition
B. I do not want install grub-loader in the Master Boot Record (that would loose my WinXP boot-loader for ever)
C. I have installed grub boot loader in the First Boot Sector
D. Now I have to boot using Rescue Mode, do:
1. dd if=/dev/sda2 of=/fat32/linux.bin bs=512 count=1
2. mount -t ntfs /dev/sda1 /ntfs
3. cp /fat32/linux.bin /ntfs
4. modify /ntfs/c/boot.ini and introduce the statement 'c:linux.bin="Linux"'
Problem: Im not able to do step D.2 above.
Symptom:
** after booting linux using the Rescue Mode: sh-3.2# chroot /mnt/sysimage sh-3.2# uname -r 2.6.27.5-117.fc10.i586 sh-3.2# mount -f ntfs /dev/sda1 /ntfs FATAL: Could not load /lib/modules/2.6.27.5-117.fc10.i586/modules.dep: No such file or directory ntfs-3g-mount: fuse device is missing, try 'modprobe fuse' as root
sh-3.2#
Observations:
* The rescue mode boots into i586 based kernel (I dont know what is the actual difference between i586 and i686 - will really appreciate if anyone can educate me about it). * The installation is only a i686 image and consequently there is *only* '/lib/modules/2.6.27.5-117.fc10.i686' dir and *no* other dir. There is no dir as xxxx.fc10.i586.
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.

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 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.
I previously had a machine that dual booted Windows 7 and Ubuntu 10.10 32 bit. I recently attempted to wipe out the 32 bit Ubuntu and install 64 bit Ubuntu.
Here what I did:
- I booted from the LiveCD, and had no problems
- I formatted /sda3 using gparted. I checked that Ubuntu resided on /sda3 via the command "sudo fdisk -l". This worked fine.
- I then clicked the "install ubuntu" option on the desktop, and chose the largest chunk of free space.
- About 15% through the install, I was told the CD could not be read from due to a potential scratch or issue. I then tried to revert back to the Os running from the LiveCD, and things went crazy. I had trouble shutting down the machine and did a hard reset.
Now, whenever I boot I am greeted with the following message:
Windows Deployment Services: PXE boot aborted
error: no such partition
grub rescue>
At the grub rescue prompt when I ls, I see:
(hd0) (hd0,4) (hd0,2) (hd0,1)
I can still boot the LiveCD. I tried that again and tried to again format sda3 using gparted but had no luck fixing the issue. When booting from the LiveCD I am also told by gparted that "sda1 does not coincide with a cylinder boundary" or something of that nature.
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

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 ?
When i boot my PC, i get this in my Fedora 16 distro. I have tried as following but none allowing me to boot anymore.
