My laptop was running Vista just fine. I had and wanted to install Linux and chose Ubuntu. I installed it to a USB and booted using this USB. It installed just fine and ran fine one time as well!When rebooting and wanting to run Windows, I got the diskcheck screen and let it run. Windows booted fine afterwards.On my next reboot all I got and still only get is the following
I have been using ubuntu 9.10 for a month. i have it installed on a 5GB separate partition of a 80 GB hard disk with my XP installed on a C drive(a separate partition ofcourse) then i had to remove it from my PC so i boot my PC with a partition manager cd and directly formatted that partition of 5GB from that software now i am having this error on my boot of PC....
grub rescue> error:unknown filesystem
I have tried a lot of commands here on this screen and nothing happens...i want to go to my XP .... and can't loose my XP OS and other data as well on different partitions.....
there was ubuntu on my pc operating system but it is strange for me so i wanted to instal windows 7 on my pc. I inserted Window 7 disk and started to install it and i formated Ubuntu but the disk what i was using was damaged and it could not complite the installation and now i dont have any programs in my pc. Problem is that i got another disk but i cant boot anymore my pc, i select drive and stuff and then comes error.
error: unknown filesystem grub rescue- i tryed different commands but those didnt worked.
I had dual boot with windows 7 and ubuntu 10.04 running, and working. In my grub menu on startup I could choose (among things) something called Vista loader. Dont know why, since I installed windows 7 and not vista. Could also choose windows7 and ubuntu, both worked.
Today I accidentally pressed the vista loader, and now I get the following error upon boot: Error unknown filesystem grub rescue
So the next thing I did was download the latest ubuntu and boot from live cd. I followed instructions [url] on how to purge grub2 and reinstall it, and did so with out any problems. However the same error remains when I boot.
I just recently decided to install Ubuntu alongside windows 7 64bit. I was working fine until I decided to increase the partition size of the unused space to take up some space of an unused partition I had made earlier. When I tried to reboot windows I got the error - error: unknown fileystem. grub rescue> I have tried a windows repair disc with no results, it cannot find any problem with the startup routine and I have looked at many different tutorials and information about how to restore grub using command from the grub rescue menu. Ubuntu 10.10
my ubuntu installation has stopped booting after i deleted and again created one of my partitions (not the ubuntu partition but my data partition). but now when i switch on my netbook it says: error: unknown filesystem grub rescue>
i used gparted live to resize. this is my disk partition structure:
before doing this, my ubuntu partition was /dev/sda7, the swap partition was /dev/sda 6, and the data partition was /dev/sda 7.
I have dual boot with Ubuntu 9.10 and Windows 7. Today, after using Partition Wizard on Windows to resize its partition, I got the following message when reboot:
I dont actually know what to do, I've been reading some threads on the internet but nothing equal to my case, only people who installed Windows after Linux and lost GRUB. Do I just need a live CD to reinstall GRUB? Can somebody tell what to do?
Yesterday I installed the latest version of ubuntu to my computer that was already running windows 7. I had everything working fine until in windows I deleted a partition that had nothing in it. After this I restarted but I can't get into either OS.
I get an error that says Error: unknown filesystem grub rescue>
If I could I would change the boot order but I can't do that (I have a Dell Studio 1747). I try F2 to enter the BIOS set up, but I still end up with that error and never get to the setup. F12 doesn't work either (F12 is for the boot order) so I can't boot from the DVD with the Win7 installation DVD as the computer just freezes and I can't get past the Dell splash screen.
I have tried to remove the coin battery on the motherboard in an attempt to reset the BIOS but that didn't work either.
F2 = error F12 = freeze Reset bios by removing coin size battery = no change
I assume there is no use reformatting the HD by attaching it to another computer and re-install Win7. Is it a motherboard problem?
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.
Background: My mother's HP laptop had Ubuntu and Vista on it, Ubuntu my brother's doing. He decided he wanted to take off Ubuntu yesterday (he had forgotten the password), and deleted the partition that it was contained within. The computer now boots to this error.
Inventory: We no longer have the install disk for Windows Vista, he cannot tell me what version he used of Ubuntu, what partition it was on, any of the specs for the machine, or generally any information about the system. All I am aware of is that error on the boot-up screen. I have nothing else to work with.
I would like to remove Grub, and Ubuntu, and leave Windows intact (the request of the owner of the computer), but I have no idea what commands I could use to get rid of either when I can't access Windows, or how to properly remove them if I did access Windows.
I had Ubuntu and Kubuntu installed to dual-boot using the GRUB loader installed by Kubuntu. I mistakenly formatted the Kununtu partition to NTFS in an attempt to install Windows XP in its place without updating grub to pull the files from my Ubuntu partition.
Now, when I go to boot the computer, I receive a the "error: unknown filesystem" and the grub rescue prompts for commands. I've attempted to boot from both a Ubuntu Live CD and a Secured Ubuntu CD with boot repair built into it, but receive the same message both times. I know this isn't an issue with my boot order (I've changed that), and my computer will boot into a Windows XP setup disc (which will not proceed for a different reason)
Yesterday I partitioned my hard drive with kubuntu netbook remix and windows 7. after a few hours and reboots i turned on my computer and it said Grub loading. unknown filesystem rescue grub> It looks like allot of people have been having similar errors recently with windows 7.
I am trying to install ubuntu 10.04 lts on three of my schools old computers, they are all old Celeron computers, all basically exactly the same, it installed flawlessly on the first one but on the second after restarting after fresh instillation it boots to an error saying "unknown filesystem, grub rescue>" I've reinstalled 3 times, I've looked for others with the same problem but they are all related to dual booting with windows, I wiped windows, there is mow windows involved
I am fairly new to linux and my laptop froze so I rebooted it and now I have this error. I have tried to load the files needed using the prompt but nothing seems to work so here is my bootinfoscript thing. Any way for me to reinstall ubuntu over the sda5 partition but keep my files?
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 #7 for /boot/grub. => Syslinux is installed in the MBR of /dev/sdb .....
I have recently updated my ubuntu 9.10 install to 10.04. And with that I've tried to install snow leopard on my computer so i can dual boot between them.the install was successful, but grub2 (that worked fine) wouldn't see the OS X install on its own partition. so i tried reinstalling it, like you do after you install windows and it would remove grub as the bootloader.That didn't work and i got a lot of messages that it wouldnt work because my partitioning (or something like that) is GPT. by the end of it i didn't have grub installed at all!so i started playing around with GParted, and while doing that i also put a bios_grub flag on my main ubuntu install partition, thinking that it would force grub to load from that partition. But that just gave me the GRUB Rescue prompt when trying to boot.
So i unchecked the bios_grub flag. and now it doesn't boot to anywhere and when inserting the ubuntu live cd i cant even see the ubuntu ext4 partition and mount it.Gparted says that its a partition that its File System is undetectable and unknown.Is there any solution that will allow me just to mount that partition and copy files from it? (unfortunatelly my backups are a little older than i would like them to be)Heres what boot info script gives me: (the partition that i need is sda1)

A few days ago I decided to try a linux OS for the first time. Following a how-to advice, I created a ~80gb partition (on a 320 gb sata disk) for Win7 and installed it. Then I installed Ubuntu 10.04, chose to make partitions manually, created a primary ext4-partition (right after the one with Win7) for / and a 1024mb swap partition. So now the disk is parted this way: 512 booter - Win7 system, ~ 80gb ntfs - Ubuntu /, 8 gb ext4 - Ubuntu 1 gb swap - file storage, ntfs ~240 gb (created using Win7 bootable disk, but the issue from below started before this).
After the installation the boot loader failed to load any system, giving the error from the topic title. I tried several ways to reinstall/repair/reconfigure grub in the live-CD mode. Some of them didn't change anything, others were not completed because of an update-grub error ("cannot find a device for / (is /dev mounted?)"). Grub version is 1.98b. The disk with Win7 and Ubuntu is treated as hd0 in grub and sdd in Ubuntu ote: even though the thread is marked as SOLVED, the issue is actually not. I have managed to dual-boot Win7 and Ubuntu, but with partition configuration changes
I have a dual boot system with ubuntu 9.10 x64 and Windows 7. Everything has been working fine for a a long time but yesterday I tried to delete an unused partition through the Disk Utility in ubuntu (System->Adminstration->Disk Utility) and everything was messed up. I used to get the "Grub error: Unknown filesystem". I managed to create an ubuntu bootable usb and followed some tutorials for fixing grub but all i managed to do is to get another error: "Grub error: No such disc". After some experimentation i got "Grub stage 1.5" which gave me a grub> command prompt./dev/sda is the drive containing Windows and Ubuntu.
[ Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 0.97 is installed in the MBR of /dev/sda and looks on the same drive in partition #6 for /boot/grub/stage2 and /boot/grub/menu.lst.
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 had a problem with my grub (system displayed "unknown filesystem" and then the grub rescue prompt). I then used a livecd of ubuntu 9.04 and ran fsck for a while (closed it in the middle). Grub then worked. But when i select ubuntu 10.04 it goes to the purple screen and stops there. There's some error before loading the purple screen.
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.
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 have recently decided to try out Ubuntu(Lucid Lynx) using wubi. Everything was absolutely superb and realizing that I have a lot to learn and looking forward to it. Everything was fine until I updated and ticked 2 boxes for updating grub and restarted and couldn't boot into anything. I have xp on 80gb 2.6 celeron, and Ubuntu loaded through wubi on 320 gb external hard drive.
error: no such device?????????????????? grub rescue>
It may seem a little slow for me to put to the test your responses, because I will have to disconnect the PC that I am using and use those connections on the 2.6. This one I am using at the moment is 400hz p3.
i have an live cd and i have tried all the methods and i am just going in circles.i am not getting any proper or definite answer.i can just open my C drive from kubuntu and im getting hundreds of errors in konsole like permission denied or bad superblock etc....
I recently plugged the hard drive from my parents' old computer into my computer's motherboard to copy some files (it's an IDE drive if that makes a difference). I copied all the old family photos and whatnot into a folder on my Vista 64bit desktop which runs off of my computer's main hard drive. I shut the computer down and unplugged the old IDE drive and tried to start it up again. After going through the typical start up screens it gets stuck on a black screen that says:"error: no such device: 66727dd9 (morenumbers).e3cbf9f71233grub rescue>_"the cursor is blinking where the underscore is. Typically, it would go to the screen where I choose whether I want to run ubuntu 10.10 or vista.I went into boot preferences and everything looks okay.. I tried plugging the hard drive into different ports on the mobo and still nothing. All my useful files are in the Vista partition of my hard drive so I'm fine with wiping everything and doing a fresh install of both vista and ubuntu so long as I can keep those files. Does anyone know what could be causing this? I've never heard of "grub rescue"
So, I had Ubuntu and Mint on my second hard drive (first drive has 7), and I reinstalled Ubuntu over the entire thing (upgraded from 10.04). Ubuntu now has one drive to itself, while Windows has the other. When I did this, I booted into Grub Rescue. Restarted and switched hard drives, same thing. I loaded the LiveCD and followed this repair guide. I discovered I don't have a Boot.cfg (or .lst) or another file of the three required. I noticed my install did not have any /boot partition, so I reinstalled a few times, all with the same error. Finally, I go back to the LiveCD desktop and run the following: sudo grub-install --boot-directory=/media/[long string]/boot /dev/sda And this is the output: Code: /usr/sbin/grub-probe: error: cannot stat: /dev/sda/ This is on Ubuntu 11.04 with GRUB2 (1.99).
